Overview of WSAA The Water Services Association of Australia (WSAA) is the peak industry body that supports the Australian Urban Water Industry. Its members and associate members provide water and sewerage services to approximately 20 million Australians and many of Australia's largest industrial and commercial enterprises.

The Association facilitates collaboration, knowledge sharing, networking and cooperation within the urban water industry. It is proud of the collegiate attitude of its members which has led to industry-wide approaches to national water issues.

WSAA can demonstrate success in the standardisation of industry performance monitoring and benchmarking, as well as many research outcomes of national significance. The WSAA Executive retains strong links with policy makers and legislative bodies and their influencers, to monitor emerging issues of importance to the urban water industry. WSAA is regularly consulted and its advice sought by decision makers when developing strategic directions for the water industry.

WSAA was formed in 1995 as a non-profit organisation to foster the exchange of information relating to the provision of urban water services between industry, government and the community, and to promote sustainable water resource management.

The Association’s main activities focus on four areas:

1 .influencing national and state policies on the provision of urban water services and sustainable water resource management

2. promoting debate on environmentally sustainable development and management of water resources and the community health requirements of public water supplies

3. improving industry performance and establishing benchmarks and industry leading practices for water service processes; and

4. fostering the exchange of information on education, training, research, water and wastewater management and treatment and other matters of common interest.

5.5 Compliance with Material Requirements Refer Clause 1.13 & 1.14, AS/NZS 4129

5.5.1 Body NUPIGECO SpA states that they only use PE 100 resins approved to PIPA and Australian standards sourced from consistent proven suppliers.

NUPIGECO has submitted an Inspection Certificates 3.1 according to EN 10204:2004 listing PE compound HE3490-LS-H which is listed in PIPA Industry Guideline POP004 – Polyethylene pipe compounds. The Certificate 3.1 (10AO-03098 dated 10.05.2010) has been issued by Borealis AG, Vienna Austria to NUPIGECO SpA.

EloPRESS fitting is manufactured from compounds that meet the material requirements listed in Table 1.1 in AS/NZS 4129-2008.

NUPIGECO uses black copolymer polypropylene PP-B (Type 2) for the EloPRESS body and locking nut.

5.5.2 Split ring The split ring is a material component of the EloPRESS compression fittings as shown in Figure 6. The split ring is moulded from Polyacetal (POM) listed in Table 1.1 in AS/NZS 4129.

5.5.3 Thrust ring The Thrust ring is a material component of the EloPRESS compression fittings as shown in Figure 6.

NUPIGECO uses copolymer polypropylene PP-B for the EloPRESS thrust ring.


5.5.4 Gasket O-ring made of NBR The Gasket O-ring is a material component of the EloPRESS compression fittings. The Gasket O-ring is made of 75 Shore nitrile rubber (NBR).

EloPRESS compression fittings including Mechanical Clamp Saddle as shown in Figures 6 & 7. This NBR O- O-ring is manufactured by LAVEL GOMMA Rubber Specialist using compound code 01/AA70NBR in compliance with AS 1646.1, DVGW E70NBR in compliance with AS 1646.1, DVGW EN 681-1 and DVGW DIN EN 682 Type GBL and certified for use in contact with potable water according to DVGW-Arbeitsblatt W 270 - Testing and assessment of enhancement of microbial growth on non-metallic materials in contact with drinking water. Refer to Appendix D.

5.5.5 Stainless steel inserts The EloFIT transition fittings are made of Galvanised Iron, Stainless Steel or Copper and are assembled through threaded or push-fit joints. EloFIT transition fittings are excluded from the scope of appraisal. So none of the EloFIT electrofusion fittings included in the appraisal contains Stainless Steel inserts.

The EloPRESS Poly to Copper transition fittings as shown in figure 10 has a Stainless Steel 304 Grip Ring (Jaw) which provides the required axial restraint for the PE-Copper pipe joint.

Grade 304 Stainless Steel is normal for these fittings and not recommended for water industry buried applications. Refer to Clause 11.

The water tight seal is created by the 'top hat' seals on the pipe (black and brown colour) and the captive O-ring inside the fitting body.

See Figure 9 for the assembly of EloPRESS Poly to Copper connector.

5.5.6 Zinc plated steel inserts EloFIT transition fittings are excluded from the scope of approval. So none of the EloFIT electrofusion fittings included in the appraisal contains Zinc plated Steel inserts.

5.5.7 Brass inserts EloFIT transition fittings are excluded from the scope of approval. So none of the EloFIT electrofusion fittings included in the appraisal contains Brass inserts.

5.5.8 Screw Threads NUPIGECO’s EloPRESS compression fittings with screw threads (male or female) such as adaptors have pipe threads in compliance with EN 10226-1 which is compatible with the WSAA requirement of ISO 7.1. TTR Institute Srl, Italy Test Report No. 1103417-001 dated 26/08/2014 conforms that male thread is in line with ISO 7.1 and EN 10226.

The ISO 7.1 specification for sealing pipe threads requires male threads to be tapered and female threads to be parallel and EN 10226-1 carries the same specification.

5.5.9 Reinforcement ring (for female thread) The reinforcement ring for the female threaded fittings is Grade 316 stainless steel.

The purpose of the SS reinforcement ring is to increase hydraulic and mechanical strength of the thread, particularly in presence of high pressure and mechanical stress of the outlet, for example continuous vibration to the threaded connection or an oversized male thread connection. SS reinforcement rings are not required for compression fittings for female threads ½”-1¼” because the plastic thickness of the outlet has the hydraulic and mechanical strength to resist the pressure and mechanical stress. For thread sizes 1 ½”-4” a SS reinforcement ring is important as the plastic thickness is proportionally smaller while the integral pressure stress applied to the thread is greater than the smaller sizes (½”-1 ¼”).


6 FITTING INSTRUCTIONS, TRAINING AND INSTALLATION For product information, PE pipeline design and other welding installation instructions, refer to Appendix A for list of NUPIGECO Technical Manual and how to access them.

WSAA has published the Polyethylene Pipeline Code - WSA 01 with significant input and peer review of the Plastics Industry Pipe Association of Australia (PIPA).

10 WATER AGENCY EXPERIENCE WITH THE PRODUCT OR FIELD TESTING REPORT

A field testing report of the NUPIGECO EloFIT electrofusion and butt welding fittings and EloPRESS compression fittings has not been submitted at this time.

While electrofusion, butt welding and compression fittings are a mature and widely installed product, the Australian water industry has had varied experience with the performance of these fittings. They are approved by many Water Agencies simply based on product certification and the knowledge that they are capable of performing well provided the installation is carried out correctly by competent well-trained installers.

Many Water Agencies are cautious particularly about the use of electrofusion fittings due to the lack of confidence in the installers. Because of the history of erratic installation quality, it is imperative that satisfactory completion of a recognised PE pipeline installation training program be a minimum pre-requisite for all PE pipeline installers. In addition it is recommended that for PE pipelines where electrofusion fittings are being used, an


attentive site supervision regime be adopted using qualified, experienced supervisors until the individual installer or contractor can demonstrate competence in all aspects of installation.

11 DISCUSSION Where stainless steel is to be buried, 316 as a minimum is recommended. Performance of 316 can still vary greatly depending on the soil conditions. Well-drained soils with high resistivity (some sands) give far better results than waterlogged soil of low resistivity (such as wet clay or estuarine swamps where 316 is not recommended). Stainless steel should be buried in a drained trench that has been backfilled with sand or crushed aggregate. Additional corrosion protection is not normally recommended for buried stainless steel as a product such as petrolatum tape can induce crevice corrosion unless it is applied with great care.

Compression fittings rely on interface pressure being maintained between the elastomeric seal and the PE pipe surface to maintain a sealed connection. Mechanical fittings, including compression fittings are normally used on PE pipe ≤ DN 90. Mechanical fittings are also normally used for repairs or changes to the pipeline as the pipe surface preparation requirements are less stringent than electrofusion.

Some water agencies consider the smaller PE pipe and compression fittings used for main to meter property services as plumbing products and they are not included in Water Agency infrastructure. Many agencies use minor size PE mains in ‘Cul-De-Sac’ installations and find PP compression fittings adequate and ‘fit for purpose’.

For information on quality polyethylene pipeline design, installation and testing processes refer to the WSAA Polyethylene Pipeline Code - WSA 01.

For pipe sizes up to and including DN 90, joints shall be the compression or electrofusion type complying with AS/NZS 4129. For new installations of pipe in diameters greater than DN 90, butt welding or electrofusion coupling jointing shall be used. Only trained and certified welders shall perform weld jointing of pipelines. Spigot and socket fusion welding shall not be permitted. Electrofusion systems shall permit manual operation and be limited to the long bodied, 4.0/4.7 mm diameter single pin connections conforming to the requirements of AS/NZS 4129.

The use of mechanically bolted jointing systems with elastomeric seals to joint PE pressure pipelines exceeding DN 63 in diameter has generally been limited to applications where pipeline fusion jointing proves impracticable and shall be subject to acceptance by the Water Agency.

Mechanical jointing systems for PE pressure pipe shall be configured to incorporate elastomeric seals and pipe gripping joint components that are specifically designed to restrain PE pipe ends from axial movement relative to the joint and to retain joint seal notwithstanding internal positive and negative service pressure fluctuations. Mechanical jointing systems to be installed on PE pressure pipelines shall, for acceptance, incorporate a 316 stainless steel ring stiffening insert that is designed to provide internal support for and tightly fit the nominated PE pipe internal bore.

Mechanical compression and thread jointed pipe fittings not exceeding DN 63 in diameter (usually in property service and cul-de-sac applications) and fusion jointed fittings in pressure applications shall comply with the requirements of AS/NZS 4129. Mechanical tapping bands for reticulation (diameter < DN 315) PE pipelines shall comply with AS/NZS 4129 Section 4.

The jointing and seal configuration systems of AS/NZS 5065 PE and PP pipes and fittings for non-pressure applications shall be designed to provide pipeline joint structural and dimensional integrity and stability during handling, installation, hydrostatic testing, burial and subsequent long term service.


Electrofusion jointing of PE pipelines offers a permanently sealed and jointed system provided the electrofusion process is carried out correctly. The electrofusion jointed PE pipeline has the potential to have life expectancy equal to and in some cases well beyond other pipeline materials and jointing systems. The PE material is corrosion resistant and correctly made joints are permanently fused to provide a high level of joint integrity against leakage and/or infiltration over the long-term. Similar to other plastic pipe systems, PE is susceptible to fatigue from cyclic pressure changes and additional design considerations must be made if used in a pumped pipeline. Refer to WSAA Technical Note TN4, plus design material information available from Nupigeco Australia.

PE pipelines are susceptible to permeation of specific organic chemicals (as are other pipeline systems) and care must be exercised if designing for installation in contaminated ground and/or brownfield sites. Seek further advice from Nupigeco Australia regarding such installations.

The appraisal concludes that:

• The NUPIGECO EloFIT electrofusion and butt welding fittings and EloPRESS compression fittings are ‘fit for purpose’ and suitable for use in water supply and sewer pressure and vacuum systems.

• The NUPIGECO EloFIT electrofusion and butt welding fittings and EloPRESS compression fittings are suitable for use with PE pipe conforming to AS/NZS 4130.

• The ISO Type 5 WaterMark Licence for the NUPIGECO range of fittings (i.e. EloFIT electrofusion and butt welding fittings and EloPRESS compression fittings) has been addressed to the satisfaction of WSAA Appraisal Network

12 LIFE EXPECTANCY Based on product certification to the nominated standard the NUPIGECO SpA EloFIT electrofusion and butt welding fittings and EloPRESS compression fittings have been rated ‘B’ – Life expectancy in excess of 50 years before replacement. This rating is only a general guide to life expectancy and may increase or decrease as a result of the quality of installation, system operating conditions, operating environment and other geographical and site specific factors.
