Trenchlessinstallation:Veryhighdemandsonpipelines

Open-trench pipe installation notonly represents a hazard to trafcand causes annoyance to local resi-dentsbutalsopermanentlydamagestheroadsurface.Thishasresultedina growing acceptance of trenchlesspipeinstallationmethods,whichcan

alsobeusedtolaypipesunderrivers,lakesortrafcroutes.

Various options are available fortrenchless pipe installation. With all

thesemethods,thereisanincreasedrisk of pipe damage. The extent ofthis damage cannot be determinedoncethepipeislaid(blackboxinstal-lation!). For this reason, pipes withaprotectiveouterlayerarerequiredand are therefore recommended bythe DVGW (German Association ofGasandWaterEngineering)fordirec-tionaldrilling(CodeofPracticeGW

321)andforpipebursting(CodeofPracticeGW323).

Trenchlessinstallationmethodsimposehigherdemandsonthepipematerial.Thepressure-bearingpipewalloftheSLM2.0 is produced from modernPE100RCplus pipe materials (Resist-

ancetoCrack),andthepipealsohasan extremely abrasion-resistant outerlayertoprotectitfromscratchesandscoring. This hard outer layer is es-sentialforblackboxinstallationandtherefore recommended by the Ger-manDVGWfortrenchlessinstallationtechniques.

Protectivefunction1Inordertopreventpipefailure,theEN

standardsandDVGWWorksheetsG472andW400-2permitabrasionsonlyto10%oftheminimumwallthick -ness.Furthermore,thedamagemustrun out smoothly so as to preventcrackinitiation.To reliably protect HDPE pipes fromscoring during trenchless installation,egeplasthas,therefore,addedtheex-traprotectivecoatingoftheSLM2.0pipe.Thesecureprotectionfromscor-ingandnotchingreliesonanaddition-

allayermadeofamineral-reinforcedpolypropylene.Thispreventsdamagefrom reaching the pressure bearingpipecore.

Protectivefunction2Thedoublelayerconstructioninhibitsfastcrackgrowth.

Protectivefunction3In operation, the protective coatingpreventsdirectcontactbetweenstonesoroldpipeshardsandthepressurebearingHDPEpipe.Thepointloadswhich arise are distributed by theprotective coating, thereby distinctlyreducingthestresspeaks.

Protectivefunction4The modern, crack resistant sub-

stance of the core pipe, made ofPE100RCplus, provides the protec-tion against crack propagation. ThetearstrengthofthismaterialhasbeendemonstratedbyitshighvaluesintheFNCTtest.

Moderninstallationproceduresmakespecial demands of pipe material.Thematerialsusedmustsatisfyaddi-tional requirements, over and abovethematerialpropertiesmonitoredac-cording to the applicable standardsandDVGWWorksheetGW335PartA2. The resistance ofthepipemate-rial to slow crack growth is critical

forthelifespanofthepipeunderex-tremeoperatingconditions,ifthepipeistoachievethestandardservicelifeof100yearsinspiteoftheincreaseddemands. In particular, resistance tostress-induced cracking can be im-provedenormouslythroughoptimisedpolymerisation. The qualities of to-daysPE100RCplusallowittoalmost

So as to be ableto make estimatesof the service lifeof pipes underadditional pointloading, Dr. Hes-

sel Ingenieurtech-nik compared tests

of pipes under internalpressure, and with additional pointloading,totheresultsfromtheFNCTtest (3R international 4/2001 and
