BorPipeEditor's Note

I am sure that many of you, like us, have experienced a busy final quarter to 2011 with many events taking place in different regions around the world. I hope that you will enjoy reading about some of the larger conferences and exhibitions which are highlighted in this issue of BorPipe.

In the Yibal Oil Field in Oman, we see another good example of how PE100 pipes can continue to operate after many years in severe conditions. Like the pipes in the Sim Sim Oil Field reported in the last edition, these pipes have been exposed to ambient temperatures of up to 53°C for 13 years and still continue to function without any problems, whereas steel and GRP pipes have failed in similar circumstances.

In a large water project near Auckland, New Zealand, a one kilometre length of 850mm PE100 pipe was installed under a conservation area using horizontal directional drilling. In order to provide extra security the pipes were produced using the high stress crack resistant polymer BorSafe HE3490-LS-H. This will help protect this important new feeder main if there had been any damage due to the difficult installation conditions and the pipe will continue to provide bulk water to support the water distribution network for many years to come.

In this edition there is an interesting discussion with Alexander Krah, of Krah AG in Germany, who manufactures large diameter spiral wound pipe production equipment. The company have already sold fifty production lines around the world and, as he states, many of his customers are already using PP-HM materials due to the superior stiffness of the material compared to PE. PP-HM materials make the product lighter and more competitive against traditional materials such as concrete or GRP. In a separate article, you will see several examples where spiral wound pipes have been used in

different applications in Europe and the Middle East.

Another interesting application for large diameter PP pipes is shown in a case study from Australia where 900mm diameter twin wall pipes are buried and filled with water. The 100,000 litres of water cool overnight to 16°C, enabling it to be used to cool the adjacent college buildings during the hot summer days.

A “Water for the World” project at the Thach Ha District Hospital in one of the poorest districts of Vietnam has been completed and is reported in this issue of BorPipe. The NGO Lien Aid carried out the design and construction work to replace the water supply and wastewater systems using PE100 pipes provided by Borouge and its customer Tifoplas. These new systems will provide the 124,000 patients and health care workers with clean drinking water and improved sanitation facilities, whilst also improving the environment for the 3,000 people living around the hospital.

As we have reached the end of yet another interesting and exciting year, all of us here at Borouge would like to thank all of you for your support in 2011 and wish you health and happiness as well as good business prospects for 2012.

As we have seen the trend for larger and larger diameter PE pressure pipe systems we are now witnessing tremendous growth of large diameter spiral wound non pressure pipelines for both utility and industrial applications. Many of these also use high modulus polypropylene materials (PP-HM) due to their significantly higher stiffness to weight ratio compared to HDPE.

An example of the use of gravity pipes in the petroleum sector is for the construction of sea intake and outfall lines. These can be as large as 3,500-4,000mm in diameter and can be a vital part of a refinery’s or power station’s cooling system or the intake and outlet for a new desalination plant. For example such large diameter spiral wound pipes are currently being produced for a major refinery project in Abu Dhabi in the Middle East. These PP pipes produced from BorECO BA212E will be used for the intake and outfall lines for large quantities of seawater which will cool the process water in a large heat exchanger. This allows the process water to be continuously

recycled thereby greatly reducing the “water footprint” of the plant which is essential in areas where fresh water is a scarce or expensive commodity. The PP-HM material is ideal for this application in that it is resistant to corrosion, easy to process and fabricate whilst being lightweight and easy to handle on site.

In Europe, 3,400mm PP spiral wound pipes were produced and used by pipe manufacturer Bauku for a sea outfall for a power station in Wilhemshaven, Germany. The hollow helical profile of the pipe was then filled with liquid concrete to provide the necessary negative buoyancy to install the pipes on the sea bed. The same producer had previously completed a 2,600mm diameter drainage system for a large project in the city of Schwarzenberg in Germany. The large diameter pipes and fittings were both produced using PP-HM material, following the contractors’ decision to abandon the initial plan to use concrete. The PP pipes provided significant weight savings and enabled a very quick

installation period of only 10 days. The associated manholes and fittings were fabricated to the specified design from welded sheets of PP-HM.

For each of the above examples, the pipes were produced using spiral winding technology. This technology, which involves the extrusion of a pipe around a steel mandrel, is licensed by a number of European companies such as Bauku and Krah. The manufacturing process is very flexible in that different sizes and stiffness of pipe can be produced using the same extrusion equipment in combination with different sizes of mandrel. This reduces the investment cost for the pipe producer making it a very attractive proposition for entering this exciting market.

Supporting the “Pipe Chain” in Australia and New Zealand

Mike Shepherd speaking at a PIPA organised seminar in Melbourne Following the earthquakes in Christchurch this church is temporarily supported by shipping containers

In order to support the local pipe industry Borouge arranged for Mike Shepherd to undertake a short tour of Australia and New Zealand where he spoke of his experiences in Thames Water using polyethylene pipe systems. This allowed the system operators, contractors and members of the pipe industry to learn from his experience and to raise any concerns that they had about the use of PE systems.

In Australia the Plastics Industry Pipe Association (PIPA) and local polymer supplier Qenos helped organise and sponsor the seminars in Melbourne, Sydney and Brisbane. In Melbourne and Sydney the main target audience was the water industry and there was a good response in both cities. The water engineers were particularly interested to learn what quality systems had been established in the UK to ensure that contractors could not cut corners on purchasing or in training their staff to correctly install the product. They were also very interested to learn about the recent renovation programme within London and the considerable savings made using PE pipe and different trenchless installation methods.

In Brisbane the audience was mainly from the coal seam gas

business which has recently expanded dramatically bringing many new people into contact with PE systems for the first time. They were eager to learn as much as possible about what to them is a relatively new technology, especially from someone like Mike Shepherd with almost 30 years experience of using PE systems. Many of their questions concerned butt fusion welding of polyethylene pipes and fittings particularly in the fairly harsh conditions of heat and dust that they would encounter in rural Queensland. He was able to show them how the simple, non-destructive, external weld bead “twist test” can be used to give a good indication of the quality of a butt fusion joint shortly after the joint has been made.

In New Zealand, seminars were held in Auckland, Wellington and Christchurch, again mainly aimed at the local water industry. Here, unlike Australia, there are no local polymer suppliers or plastic pipe industry association to organise regular technical seminars on these topics and therefore the events generated even more interest.

In Auckland, Watercare, which is now a much larger organisation following the formation of Auckland’s Super City, have been using polyethylene for some years and were keen to

share their experiences with Mike. A broad range of subjects were explored including the development and use of the “Framework procurement models” used by a number of the water companies in the UK so that they, as the eventual asset owners, end up with a system that meets their specific requirements. The trials and tribulations of holding sufficient repair assemblies such as clamps, couplers, flanges and gaskets was also of interest.

In Wellington a full afternoon was devoted to a diverse group from the separate councils and private engineering companies. They were particularly interested in the outcome of the latest research by the UK Pipeline Innovation Steering Group which evoked much debate and brought the focus to local experience on testing electrofusion joints.

Also in Christchurch a wide cross section of engineers, contractors and pipe manufacturers attended the seminar. Eight months ago in the city a major earthquake had caused considerable damage to the existing pipe network and repairs to both the water and sewage systems were underway, mainly using polyethylene pipes. Therefore interest in the seminar was high and for many of the city’s engineers it was the ideal opportunity

to hear more about PE systems, especially design, jointing and repair techniques. Since many of the repairs had to be carried out in situ there was considerable discussion about the correct use of electrofusion fittings and Mike was able to dispel a number of misconceptions about the process. Whilst he was in New Zealand Mike was able to visit some interesting installation sites, including the West Harbour sewer rising main and the Waitakere II project where Watercare are using directional drilling to install a large diameter PE100 water pipe underneath an environmentally protected area of forest.

On his return to Europe Mike said: “Overall my impression was that the presentations went well and certainly generated a fair amount of interest from the audience, judging by the number and nature of the questions they asked. The Brisbane and Christchurch sessions were particularly lively as PE systems had only recently been adopted in such large quantities and systems were being installed in quite arduous circumstances and locations, especially in Christchurch. I believe I was able to help them increase their understanding of the requirements of design and installation of PE systems and answer the concerns expressed.”

In 1998, Amiantit Oman supplied PE100 pipes and fittings produced from BorSafe HE3490-LS to the Yibal Oil Field in Oman. They were used to replace the original carbon steel piping system to transport the crude oil and water mixture to the separating tanks and to interconnect the different tanks at the Yibal A production station.

These PE100 SDR 11 pipe systems from 160 to 710 mm in diameter have since been in continuous operation at 4-5 bar pressure until today. Some of the components are exposed to full sunlight in Oman where ambient temperatures can reach 53°C in mid-summer.

Recently Borouge’s Mohana Murali visited the site to check on what had happened to the systems over the past 13 years. Sure enough the pipes and fittings were still operating with no reported problems. This had not been the case with the previously used piping systems made from steel and GRP materials, which had failed a number of times in the same situation. He found that the operators at the storage facility were extremely happy with the PE100 systems and would be happy to use similar systems in the future.

Some of your questions answered about PP-R pressure pipe systems

Borouge PP Product Manager, Cristian Hedesiu

In a series of short articles Cristian Hedesiu of Borouge talks about some of the special characteristics of PP-R materials that make them ideal for pressure pipe systems for plumbing and industrial applications. Here he discusses the main factors governing quality because in our markets there are many materials that falsely claim to be suitable for these applications, so it is important to obtain the full technical data and check it out carefully as failures of embedded heating and cooling systems can be very costly and can seriously damage the reputation of plastic materials.

What is the PP-R material supplied by Borouge and what are the main applications for PP-R systems?

Borouge produce a PP-R material which is called RA130E and although we have just started production in the Middle East this material has a long and successful track record in Europe. It is supplied in the form of natural granules which need to be mixed with a masterbatch ready for the extrusion of pipes or the injection moulding of fittings.

Pipes and fittings produced from RA130E together with the appropriate additive package are recommended for the following applications:

• Heating and cooling (under-floor heating pipes and wall cooling and heating systems)

• Plumbing systems

• Domestic hot and cold water

• Industrial pressure pipelines

The material is also ideal for producing multilayer pipes using aluminium or other plastic layers to provide reduced oxygen permeability or other specific properties.

Can you explain the differences between PP-R and other polypropylene materials?

Basically there are three types of polypropylene materials and it is important to distinguish between them because only one, PP-R is suitable for high temperature pressure applications. The different materials are categorised as follows:-

• Type 1 Polypropylene Homopolymer (PP-H): the first polypropylene material produced, consisting entirely of propylene molecules.

• Type 2 Polypropylene Block Copolymer (PP-B): propylene molecules mixed with ethylene molecules.

• Type 3 Polypropylene Random Copolymer (PP-R): polypropylene structure including ethylene molecules regularly sequenced among the propylene molecules

All three materials can be extruded or injection moulded but because of their intrinsic properties only Type 2 and Type 3 materials are used for pipe applications. Type 2 material is used primarily for non-pressure sewage and drainage pipelines and is not recommended for hot water applications. Type 3 is used for hot water systems and it is important to select only PP-R materials for this application. As it is not possible to differentiate between the different polypropylene materials by eye you should ask your supplier to provide the technical data and international certification for his product.

What are the important properties of a good PP-R material?

The ideal PP-R material for the above applications should provide good pressure resistance at elevated temperatures, excellent processing and welding characteristics and a high impact strength for handling and installation of systems in cold climates. We believe that RA130E offers the ideal balance in these properties and each batch of material is rigorously tested in order to ensure consistent performance.

The high temperature pressure performance meets all the requirements of the German DIN 16887 specification and each batch

7

of material is tested at 95°C for 1000 hours at a stress level of 3.5 MPa. What other particular qualities does RA130E have that make it superior to alternative PP-R materials?

Firstly because our feedstock in the Middle East is extremely pure the resulting material is very clean and meets all the stringent European requirements for taste and odour. This of course is very important for a product that is used for internal domestic hot and cold water transportation.

In addition to the quality of the feedstock, the unique molecular structure e.g. broad molecular weight distribution and unique stabilization package make this product suitable for high temperature and pressure

applications and also provide improved processability of RA130E compared to other materials. In recent customer trials the processing characteristics of Borouge RA130E were exceptionally good resulting in output rates that were 10% higher than competitors’ materials. Also metal inserts showed far better retention characteristics in pressure tests.

What are the important properties that pipe and fittings manufacturers should consider when choosing a coloured masterbatch?

The quality of the final pipe and fittings is also dependent upon both the raw material and the colour masterbatch. It is therefore important to choose a good quality masterbatch from a reliable supplier and also to follow strictly the

processing guidelines provided by the raw material suppliers.

Some simple things to remember when choosing a masterbatch are as follows: • Chose a coloured masterbatch based on a PP-R or PP-H material as the base resin. Other PP materials or PE can impair the mechanical and pressure strength of the extruded PP-R pipes

• Chose good quality pigments. It is crucial to ensure that the pigments do not reduce the performance of the polypropylene, thereby decreasing the service life of the pipe system.

• Ensure that the masterbatch complies with the drinking water and food contact regulations and that there is no negative effect on the organolyptic properties of the products.

Borouge will help you select a masterbatch and can provide you with a list of recommended masterbatch suppliers and we will talk further about this subject in future issues of BorPipe.

Have you any final comments?

Just to say that providing you choose a good quality PP-R material and follow the simple extrusion and moulding guidelines that we provide the system will meet the expected performance and provide a maintenance free service life greater than 50 years in accordance with the ISO standards.

Over 600 delegates attended the 2nd IWA Development Congress and Exhibition which took place in Kuala Lumpur during November.

During Singapore Water Week and the “Troubled Waters” exhibition a photographic competition was launched for all the staff at the Borouge Singapore office. The theme of the competition was “Water is Essential for Life” with the aim of highlighting the need to conserve water in a world which is facing increasing demand for its limited resources.

The entries were judged by a panel of colleagues against three main criteria –

The PE100+ Association Asian Group recently met with representatives from Sino French Water in Beijing and agreed on a five point action plan to raise the standards of PE water pipe quality in China. The Sino French Water Company is a partnership between the French water and wastewater services company, Suez Environment, and NWS Holdings Limited of Hong Kong. Sino French Water has been active in the Chinese water industry since 1992 and currently has 23 Joint Ventures for water and wastewater in 17 municipalities throughout China.

At the meeting Robin Bresser of Borouge introduced the PE100+ Association and described how they operated in China and the work carried out with the leading gas companies to improve PE pipe quality. Then Tunk Erk, Executive Vice President Technical of Sino French Water, reviewed the development of their business in China. He then presented the story of the Tangzhou Water Supply Company, the first Sino French JV Company in mainland China, and described how they had gradually introduced PE into the network accompanied by a strict quality plan. Over subsequent years the unaccounted for water (UFW) had dropped from over 30% to less than 6%. Also as the ductile iron and galvanised steel pipes were replaced by PE the customer complaints about water quality, pressure or flow had significantly reduced.

The agreed five point plan includes information sharing and technical support to ensure that only good quality PE100 compound is used in the manufacture of the company’s water pipes. This will greatly reduce the chance of premature failures which have been seen in some water projects in China. In addition the PE100+ Association agreed to help stage seminars for the Group’s Joint Venture companies throughout China to educate them in the need to purhase pipes from companies that use good quality raw material and production and test procedures. Ultimately the two parties would like to spread this knowledge throughout the whole of the water industry in China in a similar way to the Gas Industry.

During the course of the 3 day congress over 50 sessions took place in one of six meeting rooms used in the Malaysian National Conference Centre. Many speakers presented the ways in which they had made groundbreaking changes in different parts of the world including the opening speaker Ek Sonn Chan, the General Director of the Phonm Penh Water Authority. In his presentation he explained how he had revolutionised his organisation to renovate the ailing water distribution system to bring safe drinking water to over a million people in Cambodia’s capital city.

Borouge was amongst over 30 companies who had stands in the accompanying exhibition. Many of the delegates that visited the stand were keen to learn about both the products and the successful “Water for the World” projects featured on the stand. The local water engineers were particularly interested to discuss the use of high stress crack resistant PE100 pipes for pipeline renovation and for the poor soil conditions that exist in many parts of Malaysia.

emotional impact, creativity and the relevance to the theme. After much deliberation, IT Specialist Siew Aik Wee’s photograph was awarded first place. The photograph highlighted the importance of water to all creatures large or small – and as he reminded us in his caption to the picture: “every drop counts”. James Ong and Cecilia Ow Yong won the second and third place awards respectively for their photographs. Well done to you all.

The prizes were awarded in August by Singapore Communication Manager Katinka Brodahl who had been instrumental in organising the “Water for the World” event and the photographic competition supported by Marie Elena Olle, Peck Tze Kang and Charmaine Lee.

Earlier in the year a seminar was jointly organised by Special Technical Services (STS), United Pipeline Systems (UPS) and Borouge which was specifically designed for the Oil and Gas Industry. Under the title “Latest Developments in Polyolefin Piping for the Oil and Gas Industry” a number of industry

specialists presented some of the latest pipeline technology to over forty delegates from all the major oil and gas companies in Oman at the Intercontinental Hotel in Muscat.

Borouge Application Marketing Manager, Khalfan Al Muhairi, described the use of three layer PE external coatings for protecting oil

and gas pipelines. In particular he focussed on the latest top coat material Borcoat HE3450-H which is especially developed for the hotter climates in the Middle East and Asia. This material also provides additional protection from the handling and installation damage that can arise in these tough environments.

In September Prashant Nikhade from Borouge worked with Indranil Chakraborty and John Menezas of the Hallmark project team to organise a workshop for the engineers and technicians within Hallmark Aqua Equipment covering the welding and installation of PE systems. After working together closely on a successful campaign to increase the quality standards for sprinkler irrigation systems in many of the tea plantations of India it seemed the right time to build on the good relationship between the two companies.

The welding workshop covered both butt fusion and electrofusion jointing procedures with a very “hands on” approach. To provide the detailed knowledge and equipment Prashant called on the support of machine and fitting manufacturers ITS Technodue, Georg Fischer India and Kimplas Piping. In addition there were workshop sessions on best site installation practices, maintenance and repair of PE systems and a specialist irrigation consultant Mr. Ratin Chaterjee was invited to talk about some of the particular design and site

Mohana Murali also from Borouge then spoke about some of the internal pipe lining projects in the Middle East using the new high stress crack resistant material BorSafe HE3490-LS-H. This material has been specifically produced to handle tough installation conditions such as lining old corroded steel pipes and the installation of new PE pipes using directional drilling. In these operations the external surface of the pipe can be scored or damaged but the high stress crack material will resist the development of cracks from these surface defects.

At the seminar Special Technical Services (STS) and United Pipeline Systems (UPS) launched their joint venture operation for pipeline lining and renovation in the Middle East. This new company which will be called United Technical Services already has sixty experienced operators and a full range of equipment and is already active in a number of existing projects in the Middle East. They offer a full range of services but strongly focus on the “Tite Lining” technology successfully developed by UPS which ensures that there is a strong base of knowledge and experience to service the vibrant oil and gas industry in the region.

management challenges he had overcome in recent projects.The delegates greatly appreciated the workshop and afterwards Mr. P.K.Ghosh, Managing Director of Hallmark praised the event saying: “We are a quality irrigation system supplier, who are using the best materials and equipment for our products and it is also important to share our knowledge to provide the best possible service to our customers. I would personally like to thank all those who contributed to setting up this programme.”

Jinan, which is the capital of the Shandong Province on China’s east coast, became the focal point for water in September when the city hosted the 6th International Conference on Urban Water Development. The conference which was supported by the Ministry of Housing and Urban-Rural Development, Ministry of Environmental Protection, Government of Shandong Province and the Asian Development Bank attracted over 2,000 delegates.

There were twenty different sessions and workshops within the conference programme over two days and Borouge’s Cindy Wang presented a paper at the session: “Application and Industrialization for Municipal Water Treatment Equipment and Technology”. Her paper entitled “Polyolefin pipeline material selection for water supply and sewage pipes” covered the use of polyolefin materials for pipes for water supply and sewage systems. She described some of the differences between the traditional materials used in the Chinese water industry and polyolefin materials and the importance of specifying compounded PE materials for pressure pipe. It showed the experiences of engineers from many other parts of the world who had now changed to PE and PP pipes and fittings due to the technical and economic benefits offered by these systems. If for example, PE pipe is linked with no dig technologies to renovate old systems or install new ones the savings in project costs are very significant.

At the same time as the conference there was a large exhibition showing new technologies and equipment for water and wastewater management. Many of the exhibition stands showed traditional products such as iron pipes and fittings, which still hold a strong position in the Chinese water and wastewater market, but there were also some companies showing polyolefin pipe systems and newer installation technologies, such as close fit insertion using folded PE pipes.

Borouge, CH2MHill and the Abu Dhabi Distribution Company (ADDC) collaborated to give a special treat to the children of Glenelg School in Abu Dhabi when they organised a Water Monitoring Day at their ECO Club.

Andy Wedgner of Borouge started the proceedings by describing the importance of water and the

desperate situation that exists in many parts of the world where people do not have access to clean drinking water. He went on to explain about “Water Footprint”, i.e. the amount of water needed to make some familiar products, such as the 2,400 litres of water taken to produce a single hamburger. He also described the “Water for the World” initiative of Borouge and Borealis and

some of the projects undertaken to bring water to people in need in different parts of the world.

Salama Al Dhahri then described the water sampling and monitoring tests that ADDC carry out on the local water supply to ensure that high quality standards are maintained. Then after a short presentation by Delijeh Khosrow of CH2MHill the children were helped to carry out tests on water samples that they had collected earlier in the day.

The session was completed with the children receiving certificates and a number of small gifts to remind them of the event. The school Science Coordinator Dana Dababneh commented afterwards: “The children really appreciated the session and gained a new understanding of the importance of water to all living creatures on Earth including ourselves. I would personally like to thank all the contributors for making the event so interesting and entertaining.”

Sometimes we forget that the military also need water and sanitation services and need to install and renovate many kilometres of pipe at all their various bases. Some of the bases are in challenging locations such as the town of Leh in the Ladhakh region high in the mountains of Northern India whilst others are well established in the heart of cities like Delhi, Kolkata, Agra, etc.

During October the Indian Society of Trenchless Technology organized a seminar for the Military Engineering Services in their New Delhi offices. The seminar was well attended by nearly 40 delegates from military engineering services centres all over India and within the programme Prashant Nikhade of

Military Engineers Trenchless Technology Seminar in New Delhi

Prashant Nikhade of Borouge speaking to the Military Engineers in their New Delhi offices

Borouge presented the benefits of using the high stress crack resistant PE100 pipe compounds in trenchless and other demanding applications. Performance and reliability are high on the military engineers list of requirements because they are often working in remote locations where alternative services are not readily available, so they really appreciated the extra security provided by these materials. Also in some cases the pipelines need to be laid quickly to meet urgent needs and if they can construct reliable pipelines whilst avoiding some of the more time consuming elements of standard laying procedures this is a bonus for the engineers.

The Thach Ha District Hospital serves the local community in one of the poorest provinces in Vietnam. Located 340 kms to the south of the city of Hanoi the hospital was in very poor condition with a poor quality water supply, inadequate hand-washing facilities and untreated wastewater on the site. These conditions not only affected the wellbeing of the patients in the hospital but also threatened the health of the people living nearby. On discovering this situation Singapore based NGO Lien Aid drew up an action plan which they called “Life Line II” (following on from the very successful “Life Line I” project at the Hanoi Children’s Hospital) and came to ask Borouge for their support within their “Water for the World” programme.

The agreement between Lien Aid and Borouge was signed in November 2009 and the “Life Line II” project was commenced with the ambitious objectives of:-

i) Providing the 124,000 patients and health care workers with access to free drinking water 24 hours a day, 7 days a week.

Providing new water and wastewater systems for the Thach Ha District Hospital

ii) Providing improved water quality for medical procedures, hand- washing and personal hygiene for the 14,000 in-patients. iii) Constructing a new wastewater treatment system to reduce the health risk and improve the environment for the 3,000 people living around the hospital. iv) Improving the toilet facilities and conducting hygiene campaigns to encourage medical staff and patients to wash their hands and dispose of solid waste properly.

Borouge provided the BorSafe HE3490-LS compound for the project and with the help of their local agent Han Huy Trading ensured that only high quality pipes were available when required by the Lien Aid team. Quality pipe manufacturer Tifoplas based in Ho Chi Minh City produced all the PE100 pipes and delivered them to the hospital site in the summer of 2010.

These pipes have been used to deliver water from the nearby river to the newly constructed water treatment

plant at the hospital compound and also to drain the wastewater from the hospital building to the new wastewater treatment facility. All the construction work has now been completed and the Lien Aid team are preparing to train the hospital maintenance staff in the operation of the various elements and officially hand over the project to the hospital management. As planned the hospital’s toilet facilities have also been improved and hand-washing awareness raising campaigns carried out for both staff and patients.

All these tremendous improvements in the hospital facilities and the knowledge of the staff will undoubtedly improve the quality of the medical treatment for the patients in the hospital and the wellbeing of the community working and living close by.

Shanghai’s success as the economic heart of China is creating a huge strain on the city’s water management system. Recent information suggests that the population is growing at 5% per year and has now reached 23 million people who have a demand for 11 million cubic metres of fresh water each day. The existing water resources cannot meet this demand and a new clean water reservoir is being constructed in the middle of the Yangtze River. Leakage levels from the city’s water supply systems are also high and it is estimated that 30% of the existing network needs to be replaced to reduce the level of water loss to acceptable levels.

To address this challenge the China Urban Water Association organised a one day seminar immediately after their annual meeting in Shanghai to discuss the different technical solutions available. Overall more than 150 delegates attended the seminar from many different water companies

Seminar on “No Dig” technologies in the Chinese water industry Insertion of the new PE100 300mm water main in one of the green areas in Shanghai

Shanghai strives to reduce water leakage to help supply growing population

throughout China, together with representatives of engineering design companies and university lecturers.

In Shanghai and many other Chinese cities one of the challenges is to renovate pipelines that are installed under the many parks and green areas of the city without damaging these valuable environments. Clearly “No Dig” technology has an important role to play and many of the presentations focussed on the different techniques that are available. Borouge’s Dongyu Fang presented the new high stress crack resistant PE100 materials that are ideally suited for these operations. Pipes manufactured from these materials are far less vulnerable to failure from the surface scratches and scores that often arise in directional drilling, pipe bursting or close fit lining operations.

On the following day the delegates were invited to a project where the Shanghai Fengxian Waterworks Company were using “Swagelining” technology to renovate 270 metres of corroded cast iron water main under

a wooded area in the city. The new 300mm diameter PE100 pipe was pulled through a die which reduced the diameter by approximately 10% to enable it to enter the old main. Once in position the load was released and the pipe expanded to form a close fit with the old host main. To ensure that the durability of the system was maintained BorSafe HE3490-LS-H PE100 material was used to manufacture the pipe by Jiangyin David Plastics Co. Ltd. This company is one of the most well-known plastic pipe producers in China and has a 15 year successful track record of consistent supply of high quality PE water pipes for major projects in China.

PE pipes have a long and successful history in renovating old pipeline networks and dramatically reducing the leakage levels. Linked to “No Dig” technologies PE pipes provide a new pipeline at a lower cost without disturbing the life of the city or damaging the environment. Projects such as this will make a major contribution to solving the water needs of many of China’s large industrial cities.

During November the annual China Gas Association Exhibition took place in Chengdu, the two thousand year old capital of Sichuan Province in Southwest China. This is an important event in the calendar as it provides suppliers with the opportunity to

Annual China Gas Association Exhibition in Chengdu

Delegates listening to the speakers at the seminar organised at the China Gas Association Exhibition

showcase their new products and developments.

This year a special promotional event took place in parallel with the exhibition to mark the updating of the book “PE gas pipeline system” which will

be carried out by the China Gas Association in 2012. This will include contributions from all the members of the value chain, material suppliers, pipe and fitting producers, technical design institutes and end users.

At the seminar Hang Biao of Borouge presented a paper showing some of the many successful applications for PE pipes in gas distribution around the world. He highlighted the range of materials provided by Borouge, in particular the bimodal MDPE PE80 materials such as BorSafe ME3440, which were selected by gas engineers in Europe and in China because of their flexibility and ease of handling coupled with a much superior stress crack resistance compared to unimodal PE80 materials.

The Southern African Plastic Pipe Manufacturers Association (SAPPMA) Annual Technical Conference took place at the Bytes Conference Centre at Midrand on 6th September. Despite the relatively poor market conditions in South Africa the conference was attended by 180 delegates and international speakers from Europe, Australia and the Middle East who

spoke on a wide range of topics including a number of environmental and sustainability issues.

As in the previous year after a short opening session the main part of the conference was split into parallel sessions dealing with a wide range of subjects concerning plastic pipes. Andy Wedgner from Borouge presented his paper entitled “High Stress Crack Resistant PE100 and its use in the Mining Industry” in one of the afternoon sessions and drew a large audience.

Mining has always been an important issue in South Africa since the first discovery of diamonds in the 1860’s until today when it is the world’s largest producer of chrome, manganese and platinum and second largest producer of gold. Mining uses thousands of kilometres of pipeline to transport the ore slurries from the mines to the processing plant and the waste

materials to settling tanks or storage areas as well as providing a number of services for the safe operation of the mine. As it is light, easy to handle and tough with exceptional abrasion resistance polyethylene has proven to be a very popular pipeline material with mining engineers, both as a pipe and as a liner for high pressure steel pipes.

In his paper, Andy traced the development of polyethylene pipe grades from their early beginnings to the high performance materials of today. The high stress crack resistant materials, such as BorSafe HE3490-LS-H represent the latest development in performance improvement and the pipes can suffer significant surface damage without jeopardising their long service life – a fact not lost on the mining engineers in South Africa.

Alexander, many thanks for coming into the Borouge office, can you tell us a little about yourself and the development of your company?

As you probably already know Krah

is still a family owned company

started up by my father over 40

years ago. We started as a small

engineering company specialising

in the design of machines and tools

and over the years have developed

into a worldwide manufacturer

of large diameter plastic pipe

production equipment.

We have already supplied many

machines in the Middle East and

Asia through our worldwide sales

network and we support all our

customers to ensure that they are

able to provide high quality products

in all markets. In fact so far, there are

50 Krah pipe production machines in

operation worldwide.

In Borouge we see an increase in the large diameter pipe business in the Middle East in the industrial sector – what sort of other applications do you see for the products?

In Europe most of the early

development was in the production of

large diameter sewage and drainage

systems but just recently there have

been some large diameter industrial

The Growth of Large Diameter Spiral Wound Pipes: An Interview with Machine Supplier Alexander Krah of Krah AG, Germany

projects which have raised the profile

for spiral wound pipes in this sector.

Plastic pipes are lightweight and

corrosion resistant and therefore

ideal for large diameter sea water

intakes and outfalls and filling the

spirally wound core pipes with cement

provides a good alternative to using

heavy concrete anchorage blocks.

In recent years we are also seeing

large diameter pipes and storage

vessels being used in many rainwater

management systems, which are

becoming very popular with architects

and designers to combat the increase

in flooding occurring in many

countries.

Large diameter spiral wound pipes are already very popular in Europe and

are now being recognised in the Middle East as an ideal solution for both

municipal and industrial applications. For example, sea water intakes and

outfalls are required for many process industries and desalination plants that

are being built in the region and spiral wound PE or PP pipes provide a very

cost effective solution.

Krah AG in Germany is one of the foremost companies in this market sector

providing machines and technical support to pipe producers all over the

world. During a brief stop-over in Singapore the editor met with the CEO,

Alexander Krah and asked him some questions as to how he sees the future of

this interesting and growing business.

Can you tell us a little about how you see the development of the large diameter spiral wound pipe market?

At the moment, due to the financial

situation, the European market is fairly

quiet but we are also really excited

about recent developments in the

Middle East and Asia. We are already

well established in the Middle East

but we are currently receiving many

enquiries for new machines from Asia.

In Australia the mining and coal

seam gas businesses are developing

strongly and we have already supplied

a 4 metre diameter machine to a new

customer in Western Australia. In

recent days we have also had enquiries

for 6 metre diameter pipe production

in Asia, which we are seriously

considering. We are also looking at

how we might provide a lower cost

package for Asia, where the market is

certainly ready to start and perhaps will

accept lower specification equipment.

The introduction of our unique

electrofusion connection has also

been instrumental in increasing the

popularity of these large diameter

pipes, especially where installation

speed is critical as it enables the

pipes to be installed faster and more

efficiently. The pipes are produced

automatically with a socket and spigot

joint and the fusion wire is then directly

introduced into the pipe socket. Once

welded the joint area is homogenous

which greatly reduces the possibility of

leakage or of the joint pulling out under

axial or bending loads.

Obviously different applications require different designs and different materials – can you tell us how you see this balance?

We see opportunities for both PE and

PP materials in spiral wound pipes.

We have customers in Europe that

are regularly using PP-HM materials

to provide the most cost effective

products. Clearly where high stiffness

is important it makes no sense to use

PE as PP-HM materials can provide

50-60% higher stiffness.

We are confident that Borouge are

producing a high quality range of

materials in the Middle East and many

of our customers have already used

their PE100 materials in their projects.

Now we are pleased to include

Borouge BorECO BA212E PP-HM

on our list of recommended

materials.

Can you tell us what packages you sell in terms of machines and knowhow and how potential customers can contact you?

We sell machines that produce

spiral wound pipes, fittings and

manholes from 300 to 4,000mm in

diameter and in lengths from 1 to

12 metres. Product details and the

The second “Golden Bridge” or as it’s officially known the 2nd International Plastic Pipe Exchange Meeting was held in Beijing at the end of November. This conference, which was jointly organised by the China Plastics Piping Association (CPPA) and the Plastic Pipes Conference Association (PPCA), presented some of the best papers from the Plastic Pipes XV conference in Vancouver last year together with a number of presentations by local experts. At the first “Plastic Pipes Spin Off” conference in November 2009, Wang Zhanjie the Secretary General of the CPPA referred to it as a “Golden Bridge” of knowledge transfer linking East and West.

Over 350 delegates attended the conference to listen to a total of 23 presentations from technical and marketing experts on plastic pipe systems from around the world. The conference was opened by Qian Guijing, Vice Chairman of China National Light Industry Association (CNLIA) and Chairman of China Plastic Processing Industry Association (CPPIA) and Chen Lihui, a Director of the CPPA and Vice-President of China Plastics Processing Industry Association, who described the recent economic

developments in China and in particular the growth of the plastic pipes industry. They both welcomed the conference as it provided an opportunity for enterprises in China to raise their technical competence and creativity and to strengthen international communication and cooperation and he thanked the CPPA and the PPCA for making it possible. Responding Robin Bresser of Borouge and a Director of the PPCA described the history of the International Plastic Pipes Conferences since their inaugural conference in the UK in 1970 and the role of the PPCA today. He explained that their main mission was the creation and distribution of technical and application information on plastic pipes systems in order to educate and expand their safe, cost effective and sustainable use and this conference was organised as very much part of that philosophy.

In the first technical session of the conference Camille Rubeiz of the Plastics Pipe Institute of the USA presented a paper on the performance of water and gas piping systems during six past earthquakes in four countries: US (1906 San Francisco; 1989 Loma Prieta; 1994 Northridge), Japan (1995 Great Hanshin-Awaji (Kobe), Thailand (2005 Tsunami) and Columbia (1999). In all the analysis work carried out PE pipes

performed better than pipes made from other materials due to their flexibility and toughness. This has prompted the American Society of Civil Engineers (ASCE) to categorise PE pipes as having the lowest vulnerability to earthquakes compared to other pipe materials, such as ductile iron and steel.

After the lunch break, several interesting papers examined different aspects of the life cycle of polyethylene pipe including Zoran Davidovski of the European Pipelife Group who presented a Life Cycle Analysis on different plastic pipe systems which was commissioned by The European Plastic Pipes and Fittings Association (TEPPFA). From the results for PE water pipe, for example, it could be concluded that the environmental profile of the PE pipe system is mainly determined by the amount of raw material that is needed to produce the pipes and by the excavation processes related to digging up the soil and backfilling the trench with soil and sand. Because PE pipes are lightweight and can be produced in long lengths, the results compared to non – plastic materials were very favorable. All the results of this work can be found on the TEPPFA website (www.teppfa.org). Many other interesting subjects were addressed during the one day conference which once again proved to be very successful with the Chinese delegates and the additional information and the exchange of ideas will undoubtedly increase the knowledge and provide for the more sustainable development of the China plastics pipe industry.

The Plastic Pipes Conference Association (PPCA) is a “not for profit” organisation formed by three industry associations, PVC4Pipes, PPI and PE100+ Association. The PPCA organise the international series of Plastic Pipes Conferences and any profits from these conferences are re-invested in spin off conferences to transfer the latest knowledge on plastic pipes to other parts of the world.

At the end of September Borouge participated in Water Philippines – 2011 Conference and Exhibition in Manila. This annual event, which is hosted by the Philippines Water Works Association (PWWA), sets out to present the latest innovations and technology in the field of water and wastewater. With a growing population in excess of 90 million people the Philippine utility companies have many challenges in water and wastewater management. For example, in the capital city of Manila, home to 1.7 million people, the water distribution system loses over 60% of the treated water mainly from leaking pipes. As we have seen in other parts of the world pipeline renovation using trenchless technology and polyethylene (PE) pipes could dramatically reduce this level of leakage and lower the associated operation costs. The effectiveness of these technologies was presented to over 100 delegates at the conference by Borouge’s Peck Tze Kang. In her paper entitled “Using the latest materials and pipeline installation technology

to reduce water losses”, she also described the benefits of using one of the high stress crack resistant materials, such as BorSafe HE3490-LS-H for these relatively demanding techniques. She illustrated her talk with a number of examples from different parts of the world where the additional security offered by these materials had given the local engineers the confidence to tackle some very tough conditions. In the same session of the conference fitting supplier, Viking Johnson, showed how some of their latest couplings can be used to quickly connect or repair pipeline systems in conjunction with trenchless technology.

A further challenge that the Philippines authorities need to address is sanitation, because at the moment only 7% of the population are connected to the main sewerage system. In many similar conferences clear evidence has been presented of the linkage between sanitation, health and a country's economic growth making a strong case for investment in new sewage systems. Therefore it seems that there is plenty of scope for new pipelines using the

latest polypropylene pipe materials which were described by Youssef Taha of Borouge to an audience at the Expo-Technology Symposium, a smaller conference run in the exhibition hall.

Borouge had a very well designed and constructed exhibition stand that presented all the innovative plastics solutions for pipe systems and our “Water for the World” program. Instructive posters and sample displays demonstrated the new high stress crack resistant (HSCR) PE100 material, BorSafe™ HE3490-LS-H and the range of polypropylene BorECO materials used in gravity sewage and drainage applications. Other posters visualised some of the “Water for the World” projects in Vietnam and India and showed the visitors how we care for our society by delivering sustainable solutions for the availability of safe water and sanitation around the world. The stand was clearly a great success because the organisers presented Borouge with an award for being the most informative booth at the exhibition.

The 24th Annual Meeting of the Malaysian Water Engineers was held in the city of Kota Kinabalu on the northwest coast of Borneo. The city provided an ideal venue for the meeting as it has an international airport because it is a popular tourist destination, being the gateway to the Malaysian State of Sabah and the island of Borneo. Borouge were invited to make a presentation on PE systems for water distribution to the gathering together with their customer Timplas.

Over 130 water engineers attended the three day meeting which had a busy presentation schedule. Andy Wedgner of Borouge presented the paper that covered many of the quality

aspects of PE100 materials and pipe manufacture including the benefits of choosing material from the PE100+ Association listed materials. This list, which is regularly updated, includes all the PE100 materials that are regularly tested against the Association’s stringent test criteria by third party laboratories. He also showed the results of our work in China to help the gas industry identify poor quality pipes which resulted in a gradual increase in quality standards. He also described the different jointing procedures and stressed the importance of proper installer training and certification in order that the quality of the system is not undermined by poor installation.

At the conference there were 150 oral and poster presentations on a wide range of corrosion related topics and the sessions were well attended by some of the top decision makers from the Oil and Gas companies and the Engineering Consulting companies. The conference was therefore the ideal venue for Chanchal Dasgupta of Borouge to introduce the new Wehocoat field joint coating system to an Asian audience for the first time. In his presentation he outlined the need for a reliable pipeline field joint coating

In Eastern Australia coal seam gas gathering is gaining momentum and twin pipelines are being laid across this rural landscape. Because many of the areas are uninhabited it is possible to plough the pipes into the ground. This utilises a modified Fockersberger Spiderplough to guide and lay continuous lengths of PE pipe at the desired depth. Using this technique it is possible to lay several kilometres of pipe in a single day and significantly reduce installation costs.

Practical trials in Australia have shown that twin 315mm diameter pipes can be laid in this manner which would again speed up pipe laying and reduce overall costs. Despite considerable advances in welding technology the bottleneck remains of welding the 12 or 20 metre lengths of pipe prior to installation because whilst it is possible to coil long lengths of small diameter pipe it is not possible to do so in the larger sizes. This is because the minimum coil diameter to prevent buckling is approximately 20 to 35 times the pipe diameter depending upon wall thickness. This would mean that a 315mm pipe would require a drum with a central core of almost 6 metres in diameter whereas the largest size that can be easily transported would have a maximum diameter of 4.0 metres.

This apparent conflict has been overcome by some clever development work by the team at Iplex Pipelines by making the pipe oval to reduce its propensity to buckle. This is carried out by a series of contoured rollers immediately at the end of the production line that gradually reduce the height of the pipe by 45% of its diameter. The oval pipe is then wound onto the spool and transported to site. Once at the final location the pipe can be uncoiled, re-rounded and laid out along the proposed path of the pipeline ready for installation – this total operation should be carried out within 48 hours of production to limit the stresses.

Trials have shown that 250 metre lengths of pipe can be coiled onto a single spool using this method. The development team have carried out extensive laboratory tests to ensure that the pipe is not permanently damaged by this procedure and the coiling equipment is now on order. This simple yet innovative idea could save the coal seam gas operators millions of dollars and it recently won Iplex Pipelines an innovation award.

There was a small exhibition area adjacent to the seminar rooms where discussions continued during the breaks in the programme. Following many conversations with the water engineers Andy Wedgner concluded: “Many of the engineers have been frustrated by their own lack of knowledge on how to deal with the quality issues on PE pipe systems and were pleased to see that Borouge were prepared to help them. A number offered to facilitate further meetings with the Malaysian Water Industry in the near future to help them to better understand and address these issues.”

system as this had been the weak point in the otherwise exceptionally well performing 3 layer PE (3LPE) corrosion protection system. He then traced the development of the system and explained the step by step procedure to coat the joint using the robotic application head.

Since the coating material is a reactive PE resin it provides an excellent bond to the base Fusion Bonded Epoxy (FBE) coating and with the factory applied 3LPE coatings in the cutback area at each end. Showing actual data from a gas pipeline project in Finland he demonstrated that the Wehocoat system gave better performance than the alternative shrinkable sleeves and tapes as well as being faster and easier to apply. In fact this new system meets all the requirements of mainline coating and therefore the need for a separate lower level specification for field joints becomes redundant. His presentation was very well received and generated a number of questions and many discussions with engineers during the coffee breaks.

The Borouge organization in China has been growing very rapidly over the past two years and therefore in October the opportunity was taken to fully acquaint the many new employees in Shanghai with the global crisis in water and sanitation and the Borouge and Borealis “Water for the World” programme.

In the local Borouge office a number of presentations were organised and the “Troubled Waters” photographic exhibition was staged in the entrance to the building. The exhibition by the well known Belgian photographer Dieter Telemans highlights the global water crisis and gives an insight into its causes and consequences.

The seriousness of the water situation in China was described by

Borouge representatives and winners of Borouge Scholarship and Water Photo Exhibition from the East China University of Science and Technology

the guest speaker, Zheng Xiaoming, CEO of the Shanghai Fengxian Water Company. During his presentation he gave an overview of the water supply situation in the Shanghai region and explained the growing pressure on the network due to the rapidly increasing population of the city. His company was responding to these pressures by building additional reservoir capacity and replacing and renovating many kilometres of corroded and leaking iron pipes using welded, corrosion resistant polyethylene piping systems. Borouge has worked closely with the Shanghai Fengxian Water Company on a number of projects to assist them in gaining the maximum benefit from using welded PE systems and to minimise leakage. This has included the development of a whole life costing model and improving the design of the transition connections to other pipeline materials.

Borouge Marketing Manager, Robin Bresser, then explained the Borouge and Borealis “Water for the World” programme which was launched in 2007 to help to bring attention to the global water crisis. Since that time many initiatives have been implemented and many projects have been carried out which have helped over 250,000 people, mainly in poor countries in Asia. Within the programme Borouge and Borealis also support Water and Sanitation for the Urban Poor (WSUP) who are delivering water and sanitation services to some of the poorest communities in eight large cities in Africa.

After lunch the Borouge team moved to the East China University of Science and Technology in Shanghai, to host a special event which again highlighted these challenges and some of the sustainable solutions provided by plastic systems. The event reflects Borouge's strong commitment to work closely with some of the leading universities in China. During the proceedings the winners of the Borouge Scholarships and a water photographic competition were also awarded their prizes.

At the end of a challenging day Robin Bresser described the “Water for the World” programme to the students and stated: “There is a clear need for companies to take responsibility by assisting poorer people to have access to clean water and developing innovative products that help to protect our water resources. Today, more and more companies are placing the issue of water on their corporate business agenda. With 'Water for the World™', Borouge and Borealis have underlined their leadership role and are going a step further.”

The AquaPro system was developed by Vinidex Australia as a storm-water retention and management system. The large diameter polypropylene (PP) twin walled pipes are currently produced using BorECO BA212E at the company’s production facility in Wagga Wagga, Australia. Aquapro can be installed under or adjacent to buildings to act as a temporary reservoir for storm-water. This water can then be released or used in a controlled manner, making valuable use of an otherwise quickly exhausted resource.

In response to the recent extreme variability of the Australian climate these systems are becoming extremely popular and architects are starting to include them as a standard feature of new developments. Polypropylene pipes are ideal for this application since they are completely resistant to corrosion and are lightweight and easy to install.

However at the Heatherhill Secondary College in the Melbourne suburb of Springvale the system is not used for storm-water but it has been put to work as part of the air conditioning system. For although

The large diameter PP reservoirs that store 100,000 litres of water used to cool the Heatherhill Secondary College

ambient temperatures in this part of Australia can reach 40°C in mid-summer the 100,000 litres of water which is contained in the 165 metres of 900mm diameter pipe cools to around 16°C overnight. This large reservoir can then be used to cool the air that is circulated around the college buildings in the air conditioning system.

Rob Feola, of Professional Plumbing Solutions, which is the company that installed the system, is extremely

enthusiastic about the way it works. As he says: “It really seems like we are getting something for nothing as the water cools naturally overnight ready to be used again the next day. In fact this is the second cooling system we have installed on this site but it is the first time we have used the AquaPro PP pipes and we believe we have saved around 10% on the total installed costs – which is great for everyone.”

The PE100+ Association Asia Group recently organised a workshop on the PE gas piping system standards at the Beijing Gas Research Institute.

At the seminar over 30 delegates heard Steve Beech, who is the chairman of the CEN and ISO PE Gas System Committees, outline the structure of these organisations and describe some of the essential properties of PE gas pipes. He went on to describe the critical tests for PE pipelines and explain the need for good quality

compounds to meet these stringent requirements.

After his presentation there were many questions on a wide range of subjects relating to the design, manufacture and installation of PE systems. One of their main concerns was that the Chinese views on proposed changes to the specification were transferred to the committee and the agreed changes were then introduced into the Chinese specifications.

Following on from the work that NGO HEED did to construct new water supply systems for four villages in the Neelum Valley, Northern Pakistan, they have now undertaken further projects in the region. In this new phase, they are constructing new water supply systems for three communities in Jagran Nullah, whose existing schemes were severely damaged during the 2010 monsoon floods.

As before the projects are being funded by Borouge and pipes will be supplied by their local customer Sun International. In order to attain the best possible result in these extremely challenging conditions, the pipes were produced from high stress crack resistant BorSafe HE3490-LS-H PE100 material. This material is extremely tough with a high resistance to external damage and point loads. Thus it is the best material for ensuring the long life of

networks laid in rocky conditions such as in the mountainous project area.

Mubashir Niaz, President of HEED, reports that all the projects are progressing well and provided the good weather holds they should be completed by the end of the year.

In Batagran and Nattan Pattian villages, the water transmission pipeline from the source, high up in the hills, to the storage tank has been completed and they are now digging the trenches for the distribution system to the individual houses in the villages.

At the Rayan Seri and Jandar Seri villages, about 80% of the water transmission pipeline has been completed, but a cable pipe bridge with a 750 ft long span is required to complete the construction. It is planned to erect the bridge in mid December and in parallel the trenches are being dug for the distribution network.

Mubashir Niaz also reports that during his recent visit a public gathering was organised which was attended by the Minister of Education, Mian Abdul Waheed, who was there to inaugurate two schools which had also been destroyed in the 2010 floods and which had been reconstructed by HEED. He says: “The Minister highly commended the support that Borouge had extended to fund the water supply schemes in the region and this was echoed by the Community Leaders in all the villages where the water projects are being delivered.”

These projects are being funded under the “Water for the World” initiative which was launched by Borealis and Borouge in October 2007. If progress continues as planned, we will be able to bring you a further report covering the completion and inauguration of the schemes early next year.

In November the GPPA cooperated with the Plastic Pipes Conference Association (PPCA) to organise an International “Spin-off” Conference in Dubai, which combined some of the best papers of Plastic Pipes XV in Vancouver with papers from local experts. The conference attracted over 70 delegates from just about every part of the plastic pipes industry.

The conference was opened and the delegates welcomed by Hussain Lootah of Borouge, who will also be taking over the Chairmanship of the GPPA later this year. Rob Lawrence completed the formal introduction by giving a brief overview of the GPPA activities during the year and reminding delegates that in 2012 the GPPA Competence Centre in Abu Dhabi will be opened for members to use.

The first guest speaker, Camille Rubeiz, Director of Engineering for the US Plastic Pipe Institute (PPI), gave a fascinating insight into the performance of PE pipes in recent earthquakes in the USA, Japan,

Thailand and Columbia. In all these cases the results showed that PE pipes outperformed pipes made from other materials, which led the American Society of Civil Engineers (ASCE) to categorise PE pipes as having the lowest vulnerability to earthquakes. This was followed by a presentation from Khalfan Al Muhairi of Borouge who described how PE pipes were being used successfully in many new applications within the Oil and Gas Industry in the Middle East, where they were reducing corrosion and extending the life of the assets.

Environmental issues are becoming very important in everything that we do and in the next session two papers examined the impact of plastic pipe systems on the environment. In the first Mark van den Bosch of Georg Fischer reported on the work carried out by TEPPFA to analyse the carbon footprint of PE pipes and he was followed by Christophe Salles of Borealis, who described the water footprint of PE pipe systems. Both these issues are growing in importance and in the USA

and Europe they are starting to influence the decision on which pipe material will be used in some large projects.

The final session focussed on a number of technical issues. In one paper Dr Jurgen Wust gave an insight into the work that SKZ are doing on estimating the residual life of PE pipes that have already been in service for up to 40 years. The results are far better than expected and with the new tougher materials that are now available we can expect even more impressive performance in the future.

At the end of the day there was a general consensus amongst the delegates that this was the most successful GPPA event yet and Rob Lawrence closed the conference by thanking all the speakers for their contributions, the delegates for their attendance and especially his colleagues within the GPPA for all their hard work in making the event such a success.

Iplex Pipelines won the order for the 3km of 600mm diameter pipeline to transport the treated wastewater to the river with their “SewerMAX” polypropylene twin walled pipes. These pipes were deemed to be the best choice after taking into consideration all the other options such as concrete, ductile iron and GRP because they are easy to install, relatively low cost, and completely corrosion resistant. The “SewerMAX” range has also earned a good reputation

For the past few years the Saline Water Conversion Company (SWCC) have been building a number of large diameter steel pipelines across the Kingdom of Saudi Arabia for transporting water from the large desalination plants at the coast to major cities throughout the country. The biggest of them, which is under construction at the present time, will carry water from Ras Al Khair (previously known as Ras Al Zour) to Saudi Arabia’s capital city of Riyadh. The population of Riyadh was estimated to be 5 million in 2010 but this is expected to rise to 8 million by 2020 and the current water supplied from Al Jubail cannot meet the needs of this rapidly growing city.

The new twin steel water pipeline will be used to transfer desalinated water from the Ras Al Khair Integrated Water and Power Plant, 70 km northeast of Jubail, to Riyadh city. The plant will produce 1,050 MW of power for the Saudi Electricity Company (SEC) and 1,000,000 cubic metres of water per day for SWCC to distribute. The total length of the pipeline is more than 910 km and it ranges in diameter from 48 inches (1.2m) to 72 inches (1.8 m). The pipelines will start at sea level and finish in the city of Riyadh, which is at 700 metres above sea level and to raise the water to this height two pumping stations have had to be built along the pipeline.

The Three Layer Polyethylene (3LPE) coating system from Borouge was selected by the project consultants, ILF Consulting Engineers, in order to protect these critical SWCC assets. These coating systems have a very successful track record with SWCC in protecting many of their other steel pipelines from external corrosion and mechanical impact damage during storage, handling, transport and operation. The Borcoat Bimodal High Density 3LPE system also provides complete protection against other factors such as corrosive soil, high water table and severe weather in Saudi Arabia all of which had to be carefully considered to ensure these critical water pipelines would have a long and trouble free lifetime.

The Iplex “SewerMAX” range of sewer and drainage pipes are manufactured from Borouge BorECO BA212E high modulus polypropylene material at their plant in Brendale, Queensland. Due to the high stiffness of the material they produce the pipes at the lowest weight per metre compared to other plastic solutions, which further eases on site handling and installation and minimises the production costs. This material, which was developed by Borealis in Europe, is now produced by Borouge in their plant in Ruwais, Abu Dhabi and distributed to pipe producers throughout the Middle East and Asia.

Services Ltd., required from this new water main which was to be installed in this environmentally sensitive area. The knowledge that the stress crack resistance of the pipe was at least twenty times the minimum value specified in ISO4427 gave them the necessary confidence to specify PE100 pipes for this HDD installation in very difficult terrain.

The one kilometre length of 850x70.8mm PE100 pipe was manufactured by Tyco in their plant at Hamilton in 6 metre lengths using BorSafe HE3490-LS-H. The pipe was delivered to site where it was butt welded to form two 500 metre pipe strings and externally de-beaded ready for installation. The specialist drilling contractors of Central Drilling Ltd. were presented with a number of challenges by the difficult soil conditions beneath the forest but finally in late October 2011 all was ready to pull through the polyethylene main. This final stage went without a hitch and the new main will soon provide bulk water to the distribution companies who supply customers living in Greater Auckland. The use of a HSCR PE100 pipe should ensure that the main will operate without any problems for many years to come.

the bonds between the company and local academia and raise awareness on some of the global challenges that we all face. The day’s events included a workshop on the company’s scholarship programme, an award ceremony for a photographic competition and an update on the company’s “Water for the World” programme.

The “Water is Precious” photographic competition was open to students from several leading universities in China including the Eastern China University of Technology and the Beijing University of Chemicals Technology. The aim was to test the students’ creativity in highlighting the increasing demand from the world’s growing population for this increasingly limited resource.

The Saudi Arabian Oil Company is one of the largest companies in the world with thousands of engineers, designers and technicians working at the many different sites throughout the country. In order to keep these engineers up to date with the latest developments in non-metallic materials ARAMCO organise regular technical exchange meetings. Borouge were recently invited to participate in ARAMCO’s 3rd non-metallic products technical exchange meeting at Al-Ahssa in the east of the country.

More than 300 participants from ARAMCO’s operations attended the two day event, which explored the many benefits of using non-metallic solutions. Polyolefin materials such as PE and PP are extremely resistant to corrosion, tough and lightweight

During September the Kenya Standards Bureau (KEBS) held their annual Conference in the capital Nairobi under the theme “Plastics Piping for a Sustainable Future”. The Conference, which was sponsored by Borouge and major European pipe manufacturer, Wavin, attracted nearly 200 delegates to two full days of presentations covering plastic systems for a wide range of applications.

The presentations covered both water distribution and sanitation systems and there was considerable focus on the importance of product and installation quality in this developing plastic pipe market. The interim Chairman of the Kenya Plastic Pipes Association (KEPPA), Satish Shah, gave an update on the establishment of the association and explained that their constitution was substantially complete and that they were looking forward to commencing their registration process with the government.

Engineer Mucheri from Nyewasco, which is a water distribution company serving 100,000 customers in and around the town of Nyeri spoke about his experience of using PE100 systems in the Kenyan environment. In his region he had found that long coils of PE pipe provided the best solution as they reduced the number of joints and fittings that were needed and were less prone to theft or illegal connections than galvanised iron or PVC pipes. Once he had established the optimum transport, storage and handling systems for the coils he found them to be the ideal solution and had completely switched over to them for new water distribution systems. Whilst today he recognised that there were only a limited number of suppliers of high quality coiled PE100 pipes in Kenya he was confident that availability would improve as the plastics industry developed.

Borouge’s Cindy Wang then presented a progress report on the “Water for the World” programme that the company initiated in 2007 together with Borealis. She focussed mainly on the projects that Borouge had undertaken in China and South East Asia to improve clean water supplies to local communities together with local partners.

The final act in a very full day was the signing of the Responsible Care Global Charter with the Association of International Chemical Manufacturers (AICM) which commits the parties to work together with the Chinese chemical industry to share best practices. The charter was signed by Andy Liu, Regional General Manager Asia North for Borouge and the Responsible Care Senior Consultant of AICM, Ken Tsang.

The event was very successful and a similar event is planned together with the Shanghai Huadond University in October following the “Water for the World” event in the Borouge Shanghai office.

and easy to install. Borouge presented a technical paper at the workshop entitled “Polyolefin materials for larger diameter sea water and cooling systems for industrial projects”, which was an opportunity to share with the ARAMCO engineers the experience of using PE100 pipes and fittings for the Borouge 2 industrial expansion at Ruwais.

In the exhibition area Borouge had a small stand where they presented many polyolefin success stories from the Oil & Gas business. This included the use of PE100 pipes for oil flow lines and cooling water pipelines, structured wall PP pipes for sea water intake and outfall systems, the use of PE as a liner to protect water injection and oil flow lines from internal corrosion and advanced steel pipe coating systems to protect major oil and gas pipelines from external handling damage and corrosion. The engineers were very pleased to be able to discuss these alternative solutions to the problems they face daily in their operating plants and pipelines.

The Water Expo China and Water Membrane China exhibitions were held concurrently in Beijing in mid October. Borouge had a small stand at the show together with some 350 other exhibitors from 20 different countries. Whilst Borouge was the only polyolefin raw material supplier present there were several plastic pipe and fitting manufacturers present, including Georg Fischer.

On the Borouge exhibition stand there were examples of both PE and PP pipes produced from the latest Borouge materials. A featured case study demonstrated how the new high stress crack resistant PE100

material was successfully used to provide a new water supply pipeline to the joint China – Singapore Eco City in Tianjin. During the construction of the city additional water was required but the new source that the Tianjin TEDA Water Company had identified lay on the far side of the Ji Canal. They wanted to use a PE100 pipeline for speed but they were concerned about any surface damage to the pipe that could be caused by the horizontal directional drilling installation process under the canal. Ultimately they used pipe manufactured from BorSafe HE3490-LS-H high stress crack resistant material by Cangzho Mingzhu for the river crossing section to ensure that any damage incurred would not reduce the lifetime of the pipeline.

The stand also featured the new range of BorECO PP materials supplied by Borouge for the manufacture of sewage and drainage pipe together with a sample of 800 mm twin walled corrugated sewage pipe produced by Shanghai ERA. These tough lightweight systems could make a major contribution to speeding up the development of China’s sanitation infrastructure which is lagging behind the construction of water treatment plants. These products were of great

This biannual conference and exhibition was held at the Jumeriah Beach Hotel in Dubai on 10th and 11th October under the auspices of the International Society for Trenchless Technology. Trenchless Middle East is the premier regional showcase for trenchless technology which draws exhibitors, speakers and attendees from many countries, including Europe and North America. The exhibition, which featured stands from over 70 companies from 11 different countries, was well attended

with visitors from a wide range of backgrounds including engineering consultants, general and specialist contractors, utility organizations, government departments and academic institutions. The Borouge stand was a major attraction, featuring information on the latest pipe materials and case stories on many local pipe related projects.

The conference, which was attended by 180 delegates opened with a

interest to visitors from the water treatment industry who did not know that there were any alternatives to using concrete systems, which are difficult to handle and slow to install.

In addition, the stand also featured a sample of the 1,200 mm diameter PE100 pipe produced by Chinaust, which was used in the “LiangMaiQiao” water recycling project in Beijing. The pipe produced from BorSafeHE3490-LS forms part of the 7.5 km ring which will help the city meet its target for recycled water use of over 20% of the city's total water consumption by 2015.

In parallel with the exhibition the “6th China International Water Business Summit” conference was held and Borouge’s Cindy Wang presented her paper “Using the latest material & pipeline installation technology to reduce water losses” in one of the sessions. After the presentations an open panel session was held, chaired by You Jinde, General Secretary of the Membrane Industry Association of China. The main topic for discussion concerned producing drinking water using desalination, but the delegates also recognised that the integrity and quality of the water distribution system was equally important in maintaining water quality and the continuity of water supply.

presentation from ADSSC’s Managing Director Alan Thompson who gave an update on the construction of Abu Dhabi’s new sewage system. Later in the day Andy Wedgner of Borouge gave a paper entitled “The Development of HSCR Polyethylene for use in Trenchless Technology”. The paper discussed the importance of specifying and employing High Stress Crack Resistant PE100 when installing new pipelines using horizontal directional drilling and when replacing or relining existing pipelines through the use of methods such as pipe bursting, “Swagelining” and the use of folded liners. It was well received by the attendees with several questions being raised by end users such as Dubai’s RTA and specialist contractors.

Wishing all a fresh green and healthy start to 2012!
