Kev tsim kho thiab kev teeb tsa ntawm PE-RT II cov kav dej kub lub caij nplooj ntoos hlav rwb thaiv tsev yuav tsum muaj kev tswj xyuas zoo thoob plaws hauv tag nrho cov txheej txheem, nrog rau cov tub ntxhais yog kub-kua sib txuas thiab kev sib koom ua ke. Ua ntej kev tsim kho, npaj tag nrho cov ntaub ntawv thev naus laus zis kom paub meej tias qhov kub thiab txias yog qhov tsim nyog, thiab tshuaj xyuas cov kav dej thiab fittings kom zoo. Kev sib txuas ntawm cov yeeb nkab yuav tsum siv cov cuab yeej kub kub-kua tshuab, ua haujlwm los ntawm cov khoom siv tau ntawv pov thawj, muaj lub ntsej muag kawg milled kom tshem tawm cov txheej txheem oxide, muaj cov cua kub tswj ntawm 225-}230 degree, thiab xyuas kom sov thiab txias lub sij hawm yog nruj me ntsis xam raws li phab ntsa thickness. Kev ua kom txias txias tom qab sib koom thiab dej los yog cua txias yog txwv tsis pub. Thaum lub sij hawm installation, xyuam xim rau trench tiv thaiv kom tsis txhob ua puas lub anti{10}}corrosion txheej, thiab teeb tsa cov hlua ruaj khov thiab cov txheej txheem them nyiaj raws li tus qauv tsim. Kev sib koom ua ke yog qhov tseem ceeb rau kev ua haujlwm ntev -. Tom qab dhau kev soj ntsuam kev sib txuas, cov pob qij txha yuav tsum tau kho kom sai; Cov ntaub ntawv tsim nyog yuav tsum raug xaiv los xyuas kom meej tias cov txheej txheem tiv thaiv -corrosion yog qhov sib txawv -dawb thiab tsis muaj kev puas tsuaj-dawb, tsim cov qauv kev sib xyaw nrog cov yeeb nkab tiv thaiv sab nraud. Tom qab kev teeb tsa, ua qhov kev ntsuas siab: qhov ntsuas lub zog nce mus rau 1.5 npaug ntawm kev ua haujlwm siab thiab ruaj khov rau 10 feeb; qhov kev ntsuas nruj yuav tsum tsis txhob xau thiab tsis muaj qhov poob siab tom qab 30 feeb kom tsim nyog raws li kev ua haujlwm siab poob. Tsis tas li ntawd, kev thauj mus los thiab kev khaws cia yuav tsum tau tiv thaiv los ntawm lub teeb thiab noo noo kom tsis txhob muaj tshuaj lom neeg. Thaum hla-kev ua haujlwm, kev tiv thaiv cov khoom yuav tsum tau ua kom ntseeg tau, thiab ua raws li "Technical Code for Heat-Resistant Polyethylene (PE-RT II) Direct-Buried Hot Water Insulated Pipelines" thiab lwm yam qauv yuav tsum tau ua raws li kev ruaj ntseg thiab kav ntev ntawm qhov project.
