PE-RT Hom II prefabricated ncaj qha- faus insulated piping yog lub siab - cov kav dej ua tau zoo tsim tshwj xeeb rau cov kev sib txuas hauv nruab nrab hauv nroog cov cua sov. Nws cov qauv yog tus yam ntxwv los ntawm kev sib xyaw "peb-hauv-ib" configuration: ib tug cab kuj yeeb nkab, ib txheej rwb thaiv tsev, thiab ib tug txheej tiv thaiv casing. Cov txheej sab hauv yog cov yeeb nkab nqa, ua los ntawm hom II tshav kub-resistant polyethylene (PE-RT II); Nws muaj peev xwm ua tau ntev - lub sij hawm thauj cov dej kub ntawm qhov kub txog li 85℃(nrog lub siab siab siab siab ntawm 95 degree) thiab nthuav tawm zoo heev qis- qhov kub thiab txias tsis kam mus rau -40 degree, nrog rau qhov zoo xws li cov phab ntsa du, tsis muaj dej tsis kam, corrosion resistance, thiab scaling resistance. Cov txheej txheem nruab nrab muaj cov txheej txheem nruj polyurethane (PU) rwb thaiv tsev, sib txuas kom nruj rau cov txheej txheem sab hauv thiab sab nrauv los ntawm cov txheej txheem tshuaj foaming, nrog rau qhov ceev ntawm kwv yees li 60-80 kg / m³, siab kaw - cell ratio, thiab tsis tshua muaj thermal conductivity; nws ua tau zoo txo qhov kub poob thiab ua kom lub zog ua haujlwm siab. Cov txheej txheej sab nrauv yog cov khoom siv high-density polyethylene (HDPE) casing uas muaj cov dej tsis zoo, kev tiv thaiv corrosion, thiab kev cuam tshuam, tiv thaiv cov qauv sab hauv tiv thaiv cov tshuaj lom neeg hauv av thiab kev puas tsuaj. Qee cov khoom lag luam kuj tseem muaj cov yas spacers nruab nrab ntawm cov yeeb nkab nqa khoom thiab cov txheej txheem sab nrauv kom muaj kev sib koom ua ke.
Ua tsaug rau qhov kev tsim no, PE-RT Type II insulated piping muaj qhov ua tau zoo ntawm kev ua tau zoo: cov rwb thaiv tsev thermal zoo heev nrog cov cua sov tsawg, uas ua rau muaj kev txuag hluav taws xob tseem ceeb thaum lub sijhawm ua haujlwm ntev -; ib tug tsim kev pab cuam lub neej txog li 50 xyoo, deb tshaj ntawm cov tsoos steel kav; tshwj xeeb corrosion kuj yuav tsum tsis muaj ntxiv los tiv thaiv- kev kho corrosion, ua rau nws haum rau ntau hom av ib puag ncig; thiab yooj yim ntawm installation-siv cua sov- fusion lossis electro- fusion kev sib txuas thiab tso cai rau serpentine nteg yam tsis tas yuav tsum tau trenches lossis tsau thauj tog rau nkoj, tag nrho ntawm tus nqi qis. Tsis tas li ntawd, cov khoom siv kav dej tsis yog - lom thiab ib puag ncig tus phooj ywg, tsis muaj kev pheej hmoo ntawm dej paug, thiab lub kaw lus muaj cov yam ntxwv zoo heev. Ua raws li CJ / T 480-2015 tus qauv, cov khoom no tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov tshuab cua sov niaj hnub.
