Compressed airtechnology (PN16)Compressed air has become indispensablefor the manufacturing sector and is usedfor the following tasks:● Driving medium for tools● Pneumatic control systems● Driving medium for regulator fittings● Air purification at the workplace

Advantages● Range of sizes: d20 – 110● High chemical resistance to

compressor oils● No corrosion and therefore no

variation in the quality of the compressed air

The alternative pipesystem

The polymerKEtrix® is made of CRYOLEN®,a PP-based polyolefine blend.

Impermeabilityto oxygenThe molecular structure of the polymersmeans that small amounts gases diffusethrough the material at different rates.

The problem is well-known:● Carbonated drinks should not lose

any CO2

● Many foods need to be protectedfrom the effects of O2

(fats, oils, milk cheese, meat…)

● On the other hand aromas shouldnot escape(coffee, jam, vegetables….)

● Sheets act as water vapour barriersin buildings Pipes in water circulationsystems must not allow oxygen to diffuse through the pipe as this will attack the metal components and cause the following problems:– Corrosion (Iron, steel)– Incrustation– Blockages– Malfunctioning– Expensive repairs

In general these problems are solvedby using composite materials:

A combination of plastic material withother materials which provide strength ora barrier to oxygen diffusion E.g.– EVOH to prevent O2 diffusion– Fluorine polymers to prevent

H2O vapour– PA to prevent diffusion of oils

and fuels– Metal to prevent the loss of aroma

The NONOX® processKE KELIT has developed a newpatented process:

The structure of the polymer alloy makesit possible to close the ”molecular pores”by means of a ”redox” treatment.O2 molecules can no longer diffusethrough the material.

The resultKEtrix® pipes, which are madecompletely of plastic areimpermeable to oxygen when thewall thickness is a minimumof 3,7 mm.

The material was tested to ÖNORM B5157according to the zinc absorption method.

Test reports by the TGM institute in Viennashowed the following results:

Max. diffusiondefined by standard: 0,1 mg O2/d .m3

Result for Ketrix: < 0,005 mg O2/d .m3

Chilled water/airconditioning (PN10)Pipe systems for chilled water coolingsystems (down to +2°C)Pipe systems for brine refrigerationsystems (down to –30°C)

Advantages● Range of sizes: d20 - 160● Resistant to impact at –30°C● Resistant to any concentration of

glycol brines● Oxygen barrier

(NONOX® process)● Resistant to corrosion even when

the temperature unintentionally dropsbelow the dew point and at the aggressive temperature of 0°C.

The solutionKELENdrinking waterpipe system

Plastics are not”replacementmaterials”.When chosen andapplied correctly theyoften providethe better solutionfor a defined problem.

Sometimes eventhe only one!

Operating conditionsDrinking waterproblems

Corrosion● The concentration of ions in drinking

water is increasing and consequentlythe risk of using metal pipes:Chlorides: attack stainless steelSulphates: attack galvanised steelNitrates: attack copper

● Ever more problematic sourcesof water reserves have to be tappedfor the supply of drinking water

● Acid rain reduces the pH value of surface and spring water to critical levels below 7 (=neutral).External corrosion occurs as a result of new building and insulation materials and new installationmethods.

● Disinfectants (chlorine, ozone)attack copper in particular.Poisonous Cu ions are releasedinto the water!

Incrustation● Hard water causes incrustation on

the inside walls of metal materials.

The consequences:

● Higher pressure losses● Reduced flow● Blockages● Expensive repair work● Time-consuming renovation● Disruptions in the water supply

A secure supply ofdrinking wateris an essential factor fora high quality of life

Internal corrosion - Cu

External corrosion - Steel

Metal adaptorfittingsSpecial care has been taken over thechoice and quality control of the metalthreads.

The insulation (LX)Foam:

● Cross-linked PE● 100% closed pore● Density: 30 kg/m3

● Heat conductivity (λ) at:40°: 0.038 W/m°C60°: 0.039 W/m°C

● Water vapour permeabilityμ = 10,000(an effective vapour barrier)

● Environment-friendly (CFC- free foam)● Bubble structure to insulate against

noise transmission● Strong enough to withstand site

conditions● Concealed pipe can be located

electronically● Insulation can be pushed back to

allow room for the welding

Protective coating:High quality 5-layer composite made ofpolyolefines and aluminium

● Dezincification resistant brass(MS 63, CZ 132) for all parts transporting water ensures high resistance against aggressive water.

● A pore-free, chemically appliedmetal plating prevents stress corrosioncracking.

● Metal parts which are not in contact with the media are generally made of metal-plated MS 58 brass.

● Exceptional resistance to torsion forceand suitable for on-site conditions

● Depth of the thread conforms toDIN 1692 for normal faucets

● KELIT technology has made KELEN pipes particularly resistant to impact at –5°C.

● Pipes and fittings are madeof the same raw material.

The long-life plasticThe raw material is a polypropylenecopolymer (PP.R) with its typical qualitycharacteristics (DIN 8077, DIN 8078).

Every material is subject to ageing.PP-R is no exception to this rule of nature.The ”long-term creep curves”, which aredetermined by temperature and stress,are proof of the long service life(see page 13 for operating conditions).

The effectDrinking water pipes made of PP-R arewinning an ever bigger share of the worldmarket as the best possible alternative tometal pipes which are subject to corrosion.The appropriate institutions (DIN,CEN,ISO) lay down the minimum standards.

KE KELIT does more than merely meetthe minimum standards. KE KELIT providessolutions to specific economic and technicalproblems such as the heat loss in pipingsystems.

The following formula is used to calculate the heat loss:

There is a much lower heat loss throughKELEN hot water pipes than through metalpipes as a result of the vastly differentheat conductivity of the materials(PP-R λ = 0.24 W/m°C; Copper λ= 320W/m°C; Steel λ= 42 W/m°C ).This fact alone is not sufficient forKE KELIT who have gone a step further.

The d20, d25 and d32 pipes are pre-insulated at the factory with either 4 mmor 9 mm of a special insulation (LEXEL=LX)against heat loss.The results are remarkable:

The potential savingsThe difference between the heat lossthrough non-insulated and insulatedKELEN pipes over the period of a yearshows that there is a remarkable potentialfor savings.

ExampleComparison of a hotel room installationwith and without LX 4 insulation:2.7 m Riser d32 (installed in shaft)6.0 m Distributor pipe (embedded inconcrete)8.0 m Circulation pipe (embedded inmortar)Operating conditions:Hot water temperature: 60°CAverage room temperature: 25°CSystem in constant operation 365 daysper year: t 2Hot water requirement: 2 hours/day: t 1Source of energy: Electricity

Amortisation calculation

The heat loss calculated above must becompensated by the permanent supplyof extra energy. Depending on the sourceof energy (electricity, oil, gas or geothermicenergy) the costs will increaseconsiderably.

Example1KWh of electricity: 0.06 – 0.151KWh of oil/gas: 0.04 – 0.08

If we assume that the average energycost is 0.075/KWh then the reductionin heat loss of 297 KWh by installing theinsulated LX4 pipe will provide savingsamounting to: 22.28 /year.

By comparing the costsyou can make the followingconclusions:

● The extra costs of the insulationis re-paid within WEEKS.

● The total cost of the piping andthe insulation is re-paid withina few MONTHS

● This represents a rate of returnwhich cannot be matched byany other form of investmentor shares.

KELEN® polyfusionweldingwith the handwelding machine

1. The pipes and fittings are joined bypolyfusion welding at 260 C. The weldingmachines and tools are self-regulating.Just connect to the electricity supply (230V)and wait:The red light indicates that the machineis connected to the electricity supply.When the green light goes out the weldingtemperature has been reached.Work can begin.

Measure the length of piperequired and cut the pipe with theappropriate pipe cutter (up to d40 withthe pipe shears;up to d110 with the wheel pipe cutter).

1.1 Before welding the KELIT ALUcomposite pipe sufficient aluminiummust be removed by the peeler to allowthe pipe to be welded to the full depth ofthe socket. The colourless medium pipe isclearly distinctive from the protectivecovering.

Important: There should be no aluminiumin the welding area. Make a visual checkbefore welding!

The pipe can then be welded to the fittingsin the same way as the standard KELENpipe.

The welding procedure

2. Ensure that the surface of the pipesare clean and free of grease

2.1 Measure the depth of the socket andmark the insertion depth on the pipeaccordingly.

2.2 The heating time (see table) beginswhen the full insertion depth of the pipeand the whole of the socket in the fittinghave been pushed on to the welding tools.

2.3 The heating time varies according tothe pipe size (see table).Once the heating time has elapsed pushthe pipe and fitting together smoothlyand evenly without delay. The result is ahomogeneous and strong joint.

2.4 Three lines on the pipe (90 apart)act as a guide for making a straight joint.

2.5 The position of the fitting can beadjusted for a few seconds immediatelyafter the pipe and fitting have been joined.A short time later (see table) the joint iscapable of withstanding operatingconditions.

3. The low weight and high flexibilityof the material makes it possible to weldwhole sections of the piping at the workbench. Take advantage of this and savea lot of time.

4. Make sure that any joints which stillneed to made in the wall are positionedso that they are accessible with the weldingmachine.

5. The distance between the draw-offpoints at the wall can be set (for allcommon installations) both horizontallyand vertically using a template equippedwith a spirit level.

6. The pipes should be insulatedaccording to the relevant nationalstandards.

Pipe OD sec sec min

Point 1. is identical to the instructionsfor non-insulated pipes on pages20 and 21

2. Exposing the ends of the pipes

2.1 For short lengths of pipes the weldingarea can be exposed by simultaneouslysupporting the pipe on a bench andpushing back the insulation.

2.2 For longer lengths of pipes one handholds the pipe while the other hand pushesback the insulation

2.3 For especially long lengths of pipe itmay be easier if the hands are crossedover.

2.4 It is NOT necessary to cut theinsulation.

3. The welding procedure and weldingtimes are identical to point 2. of theinstructions for the standard KELEN pipe.

The following guidelines apply forall pre-insulated KELEN-LX pipes.

Polyfusion weldingof KELEN®-LX pipeswith the handwelding machine

4. SENSO pipe detection

SENSO properties LXinsulation allows the system to be locatedup to a maximum depth of 80 mm in thewall.

4.1 Follow the instructions for thedetector.

4.2 Locate where the pipe is runningboth horizontally and vertically within aradius of 50 cm from the place where thehole is going to be drilled.

Important!

The bubble structure and the goodgrip make it easy to pull back theinsulation.

Pressing the insulation to the pipecan prevent the insulation fromslipping back

4. Once the heating time is over thesaddle fitting is pushed into the pipe wallimmediately (do not twist!) and pressedfor approx. 30 sec. The melting of boththe pipe wall and the pipe surface ensuresa strong homogenous joint. After approx.10 minutes the joint can be subjected tooperating conditions.

1.1 Put the pipe in the pipe clamp.Do not tighten the clamp.

1.2 Hold down the spacing buttonand move the sliding blocks togetherusing the hand wheel until the pipe istouching the fitting or the sliding blockscan no longer move

1.3 Release the spacing button.Only now fix the pipe in the clamp.

2. Move the sliding blocks apart andpull down the welding plate.

2.1 Move the sliding blocks togetheruntil they are stopped by the lock

2.2 When the heating time has elapsedmove the sliding blocks apart briskly andquickly remove the welding plate.

3. Push the sliding blocks togetherbriskly until the pipe diameter switchcatches.

3.1 Never cool the welded joint abruptly.After a while loosen the clamp and thefinished joint can be removed from themachine.

3.2 Once the cooling time has elapsedthe joint can be subjected to operatingconditions.

Butt welding machinefor KELEN® PN10pipes

IMPORTANT:The pipes ends cannot be touched andmust be welded immediately.If this is impossible and the welding hasto be done later then the welding surfacehas to be cleaned and any greaseremoved.

1. Loosen the screws and fit the requiredreducers in the clamps

1.1 The end of the pipes should protrudefrom the clamps by no more than 30 mm.

2. Put the surface cutter between thepipe ends. Move the pipes together andremove the oxide layer on the weldingsurface by cutting away 0.2mm of thesurface. Ensure that the ends of the pipesare vertically parallel to each other(maximum deviation: 0.3 mm). Themaximum deviation horizontally is 0.5mm.

3. The welding procedure(see table on the left for welding criteria)

3.1 Before welding begins read off themanometer the pressure required to bringthe pipes together. This pressure must beadded to the joining pressure given inthe table.

3.2 Insert the heating element (temp:approx. 210 C). Press the pipe ends onthe heating element and apply the pressureas defined in 3.1 until a bead forms aroundthe complete circumference of the pipe.During the heating time the pressuremust be reduced to the heatingpressure. Once the heating time is overmove the sliding blocks apart rapidly andremove the heating element.

3.3 The change-over time (timebetween removing the heating elementand welding the pipes) should be as shortas possible.

3.4 The welding pressure should be builtup as smoothly as possible during the timegiven in the table (minimum: 0.15N/mm2)

3.5 The welding pressure must bemaintained during the cooling time.

Never cool the joint abruptly.If the weld has been done correctly adouble bead should be visible around thewhole circumference of the pipe.

1. Fix the pipe clamps to a pipe thathas already been installed. The machinewill hang at the end of the pipe.

1.1 To provide extra support the pipeshould be clamped close to a pipe bracket

1.2 A pole can be placed under the centreof gravity to support the machine ifnecessary.

1.3 The pipe should protrude far enoughout of the pipe clamp to ensure that thepipe can be fully welded into the socketof the fitting but also allow enough spacefor the welding plate.

The space between the pipe and thefitting when the sliding block hasbeen completely rolled back shouldbe approx. 100 to 150 mm.

2. Put the fitting in the clamp andsupport the fitting with the fixing elbow.The fitting must have sufficient room tomove sideways so that the whole of thesocket can be welded.

3. Put the welding plate between thepipe and fitting. Turn the hand wheel tomove the pipe and fitting on to the weldingtools. Heat the pipe and fitting.

3.1 When the heating time is overremove the welding plate and push thepipe and fitting together briskly to weldthe joint.

3.2 When the cooling time is over thejoint can be subjected to operatingconditions.

Pipe sizingPressure losses inKELEN®pipesThe total pressure loss (Δp) in theKELEN®pipe system is calculated bymultiplying the friction loss (R) by thelength of the piping (l) plus the sum (∑)of the friction losses for the individualfittings (Z).

The choice of pipe size for the watersupply is dependent on the followingfactors:● The available water pressure● Geodetic difference in height● Pressure losses through system

components● Minimum flow pressure through

faucets● Pressure losses in the pipes● The individual pressure losses of the

fittings● Type, number and simultaneous use

of the draw-off points● Flow velocityNote:For the purpose of pipe sizing it is assumedthat that there will be no reduction in theinternal diameter caused by incrustationsince the surface structure of the pipe isamorphous and the surface roughness ofthe pipe is minimal (0,007).

Guidelines for pipesizing (DIN 1988/3)1. Determine the design flow rateand minimum flow pressure for allthe draw-off fittings

The design flow rate VR is derived fromthe draw-off fitting flow rate. The tablebelow gives guideline values for the designflow rate of common types of fittings andappliances. The design flow rate VR maybe determined as a mean value using thefollowing equation.

2. Determine total flow rates andassign to pipe runs

The design flow rates for all draw-offpoints shall be added, starting at the draw-off point furthest from the water mainand ending at the water main, and thetotal flow rates so obtained assigned tothe pipe runs considered, each runextending from the fitting where the totalflow rate or pipe diameter changes untilthe next fitting.

At the junction of the cold waterpipe feeding the water heater withthe pipe that branches off, the totalflow rate comprises that of the coldand hot water side.

3. Use of total flow rate / peakflow rate

The design flow rate of all draw-off pointsshall be included in the design of watersupply system, adding the flow rate ofthe draw-off points for which continuoususe is to be assumed to the peak flow rateof the other draw-off points(continuous use being defined as uselasting more than 15 minutes).Assumptions regarding simultaneousdemand are to be based on the type ofbuilding or its occupation (e.g. residentialbuilding or communal facility).Normally it may be assumed that not alldraw-off fittings are fully open at thesame time.The conversion curves for the differentapplications are shown on pages40 and 41.

4. Determination of pipe diameter

Determine the pipe size, pressure loss andflow velocity (see tables on pages37 to 39).

5. Evaluation of head loss in termsof available pressure

The head loss shall be almost equal tobut not greater than the available totalhead loss.Maximum flow velocity

Excerpt fromDIN 1988/3

Hotels, department stores andhospitalsIf the system is equipped with draw-offfittings with a design flow rate of morethan V̇R ≥ 0,5 l/s then, where the totalflow rate is ≤ 1,0 l/s the peak flow rateshall be deemed to be equal to the totalflow rate. If the total flow rate is>1,0 l/s and ≤ 20 l/s curve K(equation: V̇S =(∑V̇R)0,366 in l/s) is usedfor calculating the peak flow rate.

Other special buildings, commercialand industrial premisesParticular considerations must be givento the extent to which simultaneousdemand is to be assumed for water supplysystems on commercial and tradepremises. The total flow rate is determinedin consultation with the operator of thesystem.

Comparison of the materials:If unhindered KELEN® pipes willexpand more than metal materialsunder the influence of heat. Theforce of heat expansion, however,is much smaller!

The force of heat expansion isdependant on the dimension of thepipe and the change in temperaturebut not on the length of piping.An important factor is the rigidity of thematerial (E-module)

The E-module of PP-R (like any otherplastic) is dependant on the temperature(see graph below)

As the temperature increases the E-moduledecreases.

1. Installing the pipes in the shaftIn practise the main risers can expand and contractlaterally in the shaft between two floors if a fixed pointis located next to the pipe that branches off from themain pipe. The distance between two fixed points shouldnot exceed 3 m. Other methods can be used toaccommodate expansion such as an expansion arm inthe pipe branching off from the riser.

2. Embedding the pipePiping that is embedded in the wall, floor screed etc….is prevented from linear expansion. The material canabsorb the pressure and tensile stress without causingany damage. If the pipes are insulated then theinsulation material provides further room for expansion.

3. Exposed piping3.1 Preventing expansion bymechanical restraint d20–d50

For aesthetic reasons KELEN ALU pipesare often preferred for exposed pipesbelow d63. Greater stability can beobtained by installing the pipes in steelchannels.

In order to achieve this stability all of thepipes must be supported by pipe channelsand all of the brackets must be fastenedtightly to the pipe to make them fixedpoints. In addition the channels are fixedto the pipe (e.g. using cable ties) exceptfor the sizes d20, d25 and d32 as thechannels for these sizes are self-locking.This method reduces the linear expansionto the same amount as steel.

3.2 Expansion loops d 63 – 110All changes in the direction of the pipecan be used to accommodate the linearexpansion. In some cases an expansionloop will be necessary.

The fixed points are arranged so that thepiping is divided into sections and theexpansion force can be guided in thedesired direction. See pages 42 –45 forthe calculations of the length of theexpansion arm.

Practical solutionsfor compensatingexpansionThe following methods can be used tocontrol the linear expansion and the forceof expansion:

● Piping that is embedded in the wall or the floor is prevented from expansion by frictional force. No extra measures are required.

● Compensation must be madefor expansion of exposed piping

● Even if the rise in temperature is onlyfor a short time sufficient compensation must be made for thistemperature difference(see pages 42, 43, 46 and 47)

● Every change in temperature will exerta force.> An expansion force will occur whenthe temperature rises.< A shrinking force will occur when the temperature falls.

The force of expansion can be calculated for every installation.However, in general the force isjust a fraction of the force whichoccurs with metal materials.

Suppliers of pipe clamps and bracketsknow the properties of the materialsand offer a range of solutions.

● Pipe channels may be used to increasethe stability of the pipe.The expansion is reduced to the samevalue as steel pipes.

● The strength of the fixed points shouldbe sufficient to compensate the expansion force.

● The specific expansion can be minimised by installing the KELIT ALUcomposite pipe (d20 – d90), especially on long pipelines.This pipe reduces the expansion by approx. 75%.

Sound controlDIN 4109 recommends the followingmeasures:

● Use low-sound faucets

● Avoid direct contact between pipesand other sound transmitting bodies when fixing the pipe.

● Avoid high pressures and highflow velocities

● Special measures should be takenfor sound sensitive areas

● Cover with sound reducing insulation

● KELEN LX pipes(4 mm or 9 mm insulation)The bubble structure of the insulationprovides excellent protectionagainst sound transmission.The high strength of the insulation cover provides a long termbarrier between the pipe and other sound transmitters.

10.• A temperature of90°C for short periodsof time is NO problemfor KELEN. Highertemperatures over

longer periods of time should be avoided.The pipe system is suited for thermaldisinfection.• The gradual or continual (max. 6months) disinfection of the pipe systemwith chlorine dioxide, chlorine or ozoneis only permitted for the cold water systemand after consultation with KE KELIT.• Excessive concentrations are not onlythreatening to health they can also causepremature ageing of pipe systems.• Copper und copper ions have adestabilising effect and their presence inthe system should be avoided.

Summary of theinstruction guidelines

KE KELIT recommends pressure testing toDIN 1988/2 for plastic pipes as statedbelow.

As a result of the material properties ofplastic pipes the pipe will expand duringthe pressure testing. The pressure testingis split into a preliminary test and a maintest. The preliminary test is sufficient forsmall sections of the piping such asconnecting pipes and distributing pipesin the wet rooms.

a) Preparation

1. After the pipes have been installed and before they are concealed the piping is filled with water and any airremoved.

2. If possible the pump should be placedat the lowest point in the system

3. The manometer should be capableof reading changes in pressure of0,1 bar and should be placed at the lowest point of the section of piping being tested.

Pressure testingfor drinking watersystems

b) Preliminary testingThe test pressure is equal to the maximumoperating pressure of the system plus 5bar (minimum: 15 bar). The test pressuremust be built up over a period of 30minutes. Within the 30 minutes thepressure should be re-adjusted 2 times(each time 10 minutes apart). After afurther period of 30 minutes underpressure testing there should be no leaksand the drop in pressure should notexceed 0,6 bar.

c) Main testingThe main testing should be carried outimmediately after the preliminary testing.The duration of the test is 2 hours. Thedrop in pressure between the end of thepreliminary testing and the end of the 2hour main test must not exceed 0,2 bar.

After the pressure testing has beencompleted we recommend issuing aconfirmed report.

Please note:● Fluctuations in the temperature

may alter the test pressure● Every pressure test is an

assessment of the current stateof the system and is no guarantee against any mistakesmade during installation.

Technical rulesfor drinking waterAssuming that the design and installationhas been done professionally werecommend that the following guidelinesare followed.

RinsingAfter pressure testing the drinking waterpipes must be rinsed.Depending on the size of the installationand how the piping is run the systemshould be rinsed in sections from thebottom to the top.Each riser is rinsed in turn and the lengthof piping should not exceed 100 m.DIN 1988/2, table 10, specifies theminimum number of draw-off points thathave to be opened. Under normalcircumstances all draw-off points shouldbe opened. The rinsing time depends onthe length of piping and should not beless than 15 seconds for each metre ofpipe. The rinsing time at each draw-offpoint should be at least 2 minutes. Afterthe pipe has been rinsed for approx. 2minutes at the last draw-off point all thedraw-off points are closed in the reverseorder to which they were opened.

7.Avoid using heat to bend the pipes(it is possible to bendthe cold pipe to a

radius of 8 x d). If the pipe has to beheated then only use hot air. Never heatthe pipe with a naked flame!Maximum temperature for bendingthe pipe: 140 C

8.Try to make the jointsfor standard sectionsof piping at the workbench before they are

installed. This saves time and increasesthe security of the system.

1.The KELEN® pipesystem is made ofplastic and needs to betreated carefully to

prevent shocks and impact on the pipeduring transportation, storage andinstallation.

2.Protect the pipes,fittings andcomponents fromlengthy exposure to

direct UV radiation from the sun.

The usual time required for storage andinstallation will have no effect on thematerial as it is stabilised against UV raysbut the material is not resistant to long-term UV exposure.

3.The welding machinesare regulated tooperate at 260 C.Welding times

are based on an ambient temperatureof 20 C.

If the ambient temperature changes thetime required to push the pipe and fittingon to the heating elements (before theheating time begins) may alter slightly.

6.The expansion ofKELEN® pipes isclearly defined andmust be accounted for

in the design and installation of the system.

Please refer to pages 42-47 regardingthe methods of accommodating theexpansion of exposed piping• KELIT Alu composite pipe (page 14)• Pipe channels (page 47)• Expansion loops (pages 42 and 43)

For longer sections of piping the fixedpoints can be located in such a way thatthe system is split into expansion zones.

Suppliers of pipe clamps and bracketsoffer a wide range of solutions.

5.Do NOT screw anythreaded pipes or anycast iron fittings intothe female threads of

the metal moulded fittings.Only join to faucets and components withstraight threads. The threaded joint canbe sealed by the usual methods (hemp,paste, tape …).Do not over twist the threads.

4.Any corrections to thealignment of pipe andfitting up to amaximum of 5 must

be made during the welding procedure(see pages 18 – 25 for the permissibletime for adjustments). Any later correctionswill damage the joint.

Project references and satisfiedcustomers are the primarybenchmark for real quality.

It is imprudent to pay too much but it isworse to pay too little. When you pay toolittle, sometimes you lose everything sincethe object you have bought cannot fulfilthe task it has been set. According to thelaw of the economy it is not possible toacquire high value with little money.

Accept the lowest offer and you take therisk that you may need to incur extracosts. If this is the case then you also haveenough money to pay for somethingbetter.”

(K. Ruskin English social reformer 1819-1900)

”There is hardly anything in this world thatsomebody cannot do a little bit worse andsell at a lower price. People who are onlydictated by price are easy prey for suchmachinations.
