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.There is a much lower heat loss throughKELEN hot water pipes than through metalpipes as a result of the vastly different heatconductivity 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 for KE KELITwho have gone a step further.The d20, d25 and d32 pipes are pre-insulatedat the factory with either 4 mm or 9 mmof a special insulation (LEXEL=LX) againstheat 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: ElectricityHeat loss Q R (W/m)Annual heat loss (W)The following formula is used to calculate the heat loss:Amortisation calculationThe heat loss calculated above must be compensatedby the permanent supply of extraenergy. Depending on the source of energy(electricity, oil, gas or geothermic energy)the costs will increase considerably.Example1KWh of electricity: e 0.06 – 0.151KWh of oil/gas: e 0.04 – 0.08If we assume that the average energycost is e 0.075/KWh then the reductionin heat loss of 297 KWh by installing theinsulated LX4 pipe will provide savingsamounting to: e 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.Blue line = blue chip = secure tip16 17

The six ways ofjoining the pipesA wide range of safe and secure methodsfor joining the pipes is essential for a pipesystem.KE KELIT has a comprehensive range offittings for each method of joining.1. Polyfusion weldingPrinciple:Fusion welding occurs when alarge area of the outside ofthe pipe and the inside of thesocket are welded togetherA wide range of weldingfittings is availableSizes: d20 – d110All KELEN polyfusion fittings fromd20 to d110 are rated PN20.They can be used for welding topipes of all pressure ratings.Advantages● Pipe and fitting are madeof the same material.No additional materialsare required.● Welded joints are not aweak point in the system● Pipe can only enter thefitting after they havebeen heated on thewelding machine(important safety feature)● The weld does not causea reduction in the flow atthe joint.3. Threaded adaptor fittingsSizes:d20 x 1/2”– d75 x 2 1/2”The threads conform toDIN 2999 and are made ofdezincification resistant brass(MS63-CZ 132). They are metalplatedto protect against stresscorrosion cracking. Male andfemale threads are available asboth straight and elbow fittings.4. Flange connectionSizes: d20–d160The solution for flangedfittingsBacking ring conforms topipe sizesFusion welding: d20 – d125Butt welding: d1605. Detachable union fittingsSizes: d20 x 1/2”– d90 x 3”3 types:Advantages● Wide range of fittingsFemale thread is astraight thread● Male thread is taperedand roughened● Thread is firmly anchoredin the fittingHigh resistance to twistingstrainAdvantages● Can be detached atany time● Elastic EPDM seal● Dimensions conformto DIN 2501-PN16Advantages● Detachable fittings● Elastic EPDM fittings● KE57 fitting forconnecting to appliances2. Butt weldingPrinciple:After the end of the pipe has been cutflat the face of the pipe and fitting aresimultaneously heated to meltingtemperature. They are then pressedtogether under pressure until thematerial has cooled.Advantages● Pipe and fitting are madeof the same material. Noadditional materials arerequired.● Welded joints are not aweak point in the system.● The weld does not causea reduction in the flow atthe jointSizes: d125–d160KE55-PPR-male thread KE56-PPR-PPR KE57-PPR-male thread6. Electrofusion weldingSizes: d20–d160KELIT E-welding sockets maybe considered for welding inconfined areas.Advantages● Repair socket forconfined areas● Welding machineavailable at KE KELIT● Each fitting is packagedindividuallyInstruction sheet andcleaning tissue areenclosed18 19

KELEN ® polyfusionwelding with thehand welding machine1.11. 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 machine isconnected 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 the appropriatepipe cutter (up to d40 with the pipeshears;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.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 smoothly andevenly without delay. The result is a homogeneousand 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 jointis capable 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 positioned sothat they are accessible with the weldingmachine.Welding times4.2.1d160:The welding procedure2. Ensure that the surface of the pipesare clean and free of grease2.1 Measure the depth of the socketand mark the insertion depth on the pipeaccordingly.5. The distance between the draw-offpoints at the wall can be set (for all commoninstallations) both horizontally andvertically using a template equipped witha spirit level.6. The pipes should be insulated accordingto the relevant national standards.5.20 21

Polyfusion weldingof KELEN ® -LX pipeswith the handwelding machineImportant!The bubble structure and the goodgrip make it easy to pull back theinsulation.Pressing the insulation to the pipecan prevent the insulation fromslipping backThe following guidelines apply forall pre-insulated KELEN-LX pipes.Point 1. is identical to the instructionsfor non-insulated pipes on pages 20 and 212. Exposing the ends of the pipes2.1 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 insulation2.3 For especially long lengths of pipe itmay be easier if the hands are crossed over.2.4 It is NOT necessary to cut the insulation.3. The welding procedure and weldingtimes are identical to point 2. of theinstructions for the standard KELEN pipe.4. SENSO pipe detectionThe SENSO properties of the LXinsulation allows the system to be locatedup to a maximum depth of 80 mm in thewall.4.1 Follow the instructions for the detector.4.2 Locate where the pipe is running bothhorizontally and vertically within a radiusof 50 cm from the place where the hole isgoing to be drilled.Welding KELEN ®saddle fittings1. The surface of the pipes and saddlefittings should be free of grease, cleanand dry.2. A hole is drilled in the pipe usinga 24 mm saddle drill.3. The pipe wall and the saddle fittingare heated simultaneously with the speciallydesigned welding tools for approx. 30 sec.4. Once the heating time is over the saddlefitting is pushed into the pipe wall immediately(do not twist!) and pressed for approx.30 sec. The melting of both the pipe walland the pipe surface ensures a stronghomogenous joint. After approx. 10 minutesthe joint can be subjected to operatingconditions.22 23

Table weldingmachine1. Screw the required heatingelements to the welding plate.The length of the heating element variesaccording to the size of the pipe and thesection of pipe to be welded.2. One side of the pipe clamps canbe used for small pipe sizes (d20 – d40).For larger sizes (d50 – d90) the clampsshould be turned around.3. The same principle applies for thefittings clamps.See pages 20 and 21 for instructionson preparing pipes and fittings forwelding.4. Set the pipe diameter switch tothe required size. This switch regulatesthe length of the pipe that will be weldedinto the socket5. Spacing button.Press the button to fix the distancebetween the two sliding blocks which willenable the appropriate section of pipeand the complete socket of the fitting tobe heated on the welding elements.Note: The machine is available intwo sizes:Type 1: d20–90 mmType 2: d25–125 mmThe welding procedure:1. Fix the fitting in the clamp and thefitting holder. Ensure that the face of thefitting is flat against the clamp.1.1 Put the pipe in the pipe clamp.Do not tighten the clamp.1.2 Hold down the spacing button and movethe sliding blocks together using the handwheel until the pipe is touching the fitting orthe sliding blocks can no longer move1.3 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 lock2.2 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 switch catches.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.24 25

Overhead weldingmachineIt is recommended to use theoverhead welding machine forexposed piping in confined areas(d50–d110).1. Fix the pipe clamps to a pipe thathas already been installed. The machine willhang at the end of the pipe.1.1 To provide extra support the pipe shouldbe clamped close to a pipe bracket1.2 A pole can be placed under the centreof gravity to support the machine if necessary.1.3 The pipe should protrude far enoughout of the pipe clamp to ensure that the pipecan be fully welded into the socket of thefitting but also allow enough space for thewelding plate.The space between the pipe and thefitting when the sliding block has beencompletely rolled back should beapprox. 100 to 150 mm.2. Put the fitting in the clamp and supportthe fitting with the fixing elbow. The fittingmust have sufficient room to move sidewaysso that the whole of the socket can be welded.3. Put the welding plate between the pipeand fitting. Turn the hand wheel to move thepipe and fitting on to the welding tools. Heatthe pipe and fitting.3.1 When the heating time is over removethe welding plate and push the pipe and fittingtogether briskly to weld the joint.3.2 When the cooling time is over the jointcan be subjected to operating conditions.28 29

Pipe sizingPressure losses inKELEN ® pipesThe total pressure loss (∆p) in the KELEN ® pipesystem is calculated by multiplying the frictionloss (R) by the length of the piping (l) plus thesum (∑) of the friction losses for the individualfittings (Z).Total pressure loss ∆p∆p = (I · R + ∑Z) in PaThe choice of pipe size for the watersupply is dependent on the followingfactors:● The available water pressure● Geodetic difference in height● Pressure losses through systemcomponents● Minimum flow pressure through faucets● Pressure losses in the pipes● The individual pressure losses of thefittings● Type, number and simultaneous useof 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).Maximum flow velocityaccording to DIN 1988Maximum design flowvelocity for a given pipe run ≤ 15 minm/s>15 minm/sService pipes 2 2Supply mains:pipe runs with low head lossin-line valves(ζ < 2.5) 5 2In-line valveswith greaterloss factor 2,5 2Fitting Symbol CoefficientζGSGuidelines for pipesizing (DIN 1988/3)1. Determine the design flow rateand minimum flow pressure for allthe draw-off fittingsThe design flow rate V R 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 V R may bedetermined as a mean value using thefollowing equation.V˙R = V˙min + V˙max22. Determine total flow rates andassign to pipe runsThe design flow rates for all draw-off pointsshall be added, starting at the draw-offpoint furthest from the water main and endingat the water main, and the total flowrates so obtained assigned to the pipe runsconsidered, each run extending from thefitting where the total flow rate or pipe diameterchanges until the next fitting.At the junction of the cold water pipefeeding the water heater with thepipe that branches off, the total flowrate comprises that of the cold andhot water side.3. Use of total flow rate/peakflow rateThe design flow rate of all draw-off pointsshall be included in the design of watersupply system, adding the flow rate of thedraw-off points for which continuous use isto be assumed to the peak flow rate of theother draw-off points(continuous use being defined as use lastingmore than 15 minutes).Assumptions regarding simultaneous demandare to be based on the type of buildingor its occupation (e.g. residential buildingor 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 diameterDetermine the pipe size, pressure loss andflow velocity (see tables on pages37 to 39).5.

Force of heatexpansionThe force of linear expansion is differentfor each material. The specific force of heatexpansion is calculated according to thefollowing formula:F t = E · A · α · Δ t1000The 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)Comparison of the materials:If unhindered KELEN ® pipes willexpand more than metal materialsunder the influence of heat.

Installing KELEN ®1. Installing the pipes in the shaftIn practise the main risers can expand and contract laterallyin the shaft between two floors if a fixed point is located nextto the pipe that branches off from the main pipe. The distancebetween two fixed points should not exceed 3 m. Other methodscan be used to accommodate expansion such as an expansionarm in the 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 can absorbthe pressure and tensile stress without causing any damage.If the pipes are insulated then the insulation material providesfurther room for expansion.3. Exposed piping3.1 Preventing expansion bymechanical restraint d20–d50For 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.Guidelines for distance between pipesupport pointsThe distances between the support points given below (in cm)prevent KELEN ® pipes from sagging when they are filled withwater and there are NO pipe channels.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.

Pressure testingfor drinking watersystemsKE 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) Preparation1. After the pipes have been installedand before they are concealed thepiping is filled with water and any airremoved.2. If possible the pump should be placedat the lowest point in the system3. The manometer should be capableof reading changes in pressure of0,1 bar and should be placed at thelowest point of the section of pipingbeing tested.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:l Fluctuations in the temperaturemay alter the test pressurel Every pressure test is anassessment of the current stateof the system and is noguarantee against any mistakesmade during installation.Drinking water – Pressure test reportLocation: –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––Project: –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––Length of piping:Length of piping:Length of piping:Length of piping:Length of piping:Length of piping:Test: Yes NoVisual check:Test pressure:Preliminary test:Testing time = 60 min.Pressure after 1 hour:Main test:Testing time = 120 min.Pressure after 2 hoursLocation of highest outlet:Ambient temperature:The piping is free of leaks:d 16 _ _________ md 20 _ _________ md 25 _ _________ md 32 _ _________ md 40 _ _________ md 50 _ _________ mLength of piping:Length of piping:Length of piping:Length of piping:Length of piping:Length of piping:❏❏___________ bar (minimum: 15 bar)___________ bar (max. pressure drop: ≤ 0,6 bar)___________ bar (max. pressure drop: ≤ 0,2 bar)___________ m above the manometer___________ ° CComplaints: – ––––––––––––––––––––––––––––––––––––––––––––––––❏d 63 _ _________ md 75 _ _________ md 90 _ _________ md 110 _________ md 125 _________ md 160 _________ m– ––––––––––––––––––––––––––––––––––––––––––––––––ConfirmationPerson in charge: _ _______________________________________________Date: ______________________ Time: from ____________ to _ ____________Client: _ ______________________________________________________signature/stamp48 49

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.DIN 1988/2Sound controlDIN 4109 recommends the followingmeasures:l Use low-sound faucetsl Avoid direct contact between pipesand other sound transmittingbodies when fixing the pipe.l Avoid high pressures and highflow velocitiesl Special measures should be takenfor sound sensitive areasl Cover with sound reducing insulationl KELEN LX pipes(4 mm or 9 mm insulation)The bubble structure of the insulationprovides excellent protection againstsound transmission.The high strength of the insulationcover provides a long termbarrier between the pipe and othersound transmitters.Largest nominal diameterof the distributing pipe DN 25 32 40 50 65 80 100Minimum flow through thecompletely full distributing pipe I/min 15 25 38 59 100 151 236Minimum number of draw-offpoints to be opened DN15 1 2 3 4 6 9 14Minimum flow and minimum number of draw-off points to be opened for rinsing ata minimum velocity of 0,5 m/soHeat insulation forpotable water pipesDrinking water pipes (cold)Cold water pipes need to be insulatedagainst warming and condensation.It must be ensured that the water qualityis not reduced as a result of the waterwarming.DIN 1988/2 specifies the minimuminsulation thickness for potable waterpipes when the medium temperature isassumed to be 10°C.Type of InstallationExposed pipework in an unheated room (e.g. cellar)Exposed pipework in an heated roomPipework underground with no adjacent hot water pipesPipework underground next to hot water pipesPipework in wall, riserPipework on concrete ceilingDrinking water pipes (hot)We recommend that hot water pipes areinsulated in accordance with DIN 1988/2.If there is no requirement for hot waterin circulation it is usually possible to dowithout insulation for pipes up to 25 mm.Even thin insulation reduces theheat loss considerably!See pages 16 and 17.Thickness of insulationmm4 KELEN LX-49 KELEN LX-94 KELEN LX-413 KELEN+Insulation4 KELEN LX-44 KELEN LX-450 51

Summary of theinstruction guidelines1.The KELEN ® pipesystem is made ofplastic and needs to betreated carefully toprevent shocks and impact on the pipeduring transportation, storage andinstallation.2.Protect the pipes,fittings andcomponents fromlengthy exposure todirect 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 termUV exposure.3.The welding machinesare regulated tooperate at 260° C.Welding timesare 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.4.Any corrections to thealignment of pipe andfitting up to amaximum of 5 mustbe made during the welding procedure(see pages 18 – 25 for the permissibletime for adjustments). Any later correctionswill damage the joint.5.Do NOT screw anythreaded pipes or anycast iron fittings intothe female threads ofthe 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.6.The expansion ofKELEN ® pipes isclearly defined andmust be accounted forin 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.7.Avoid using heat tobend the pipes(it is possible to bendthe cold pipe to aradius of 8 x d). If the pipe has to be heatedthen only use hot air. Never heatthe pipe with a naked flame!Maximum temperature for bendingthe pipe: 140°C8.Try to make the jointsfor standard sectionsof piping at the workbench before they areinstalled. This saves timeand increases the security of the system.9.Once the system hasbeen installed itshould be subjected topressure testing.You can copy pages 48 and 49 of thecatalogue to make a test report.10.• A temperature of90°C for short periodsof time is NO problemfor KELEN. Highertemperatures over longerperiods of time should be avoided. Thepipe system is suited for thermal disinfection.• The gradual or continual (max. 6 months)disinfection of the pipe system with chlorinedioxide, chlorine or ozone is only permittedfor the cold water system and after consultationwith KE KELIT.• Excessive concentrations are not onlythreatening to health they can also causepremature ageing of pipe systems.• Copper und copper ions have a destabilisingeffect and their presence in the systemshould be avoided.11.The followingprecautions can bemade to ensure thatthe maximumoperating temperature is not exceeded:• Monitor and regulate solar energystorage.• Check the electric connections to the hotwater storage before the system isoperated.• We recommend installing in the hotwater piping a mixer valve which isregulated by the boiler.12.In order to qualify forguarantee cover eachinstallation must useKELEN ® system partsonly.13.In order to install theKELEN® systemcorrectly a minimalamount ofexpenditure is required for tools For yourown security we recommend that you useand maintain the tried and trusted tools.14.If you are in doubt donot hesitate to consultour technicians.There is not always aperfect solution but we can always help.52 53
