PPR cov kav dej insulated muaj peb txheej txheej: cov yeeb nkab ua haujlwm sab hauv, txheej rwb thaiv tsev, thiab cov txheej tiv thaiv sab nrauv; xaiv cov ntaub ntawv nyob ntawm tej yam kev khiav hauj lwm. Cov yeeb nkab ua haujlwm sab hauv feem ntau yog ua los ntawm random copolymer polypropylene (PPR), txawm tias lwm txoj hauv kev xws li PP-B (kev cuam tshuam- tiv taus, haum rau dej txias), PP-H (siab zog tab sis nkig ntawm qhov kub tsawg), los yog FRPP (iav fiber ntau reinforced, corrosion- resistant.) kuj tseem siv tau. Rigid polyurethane ua npuas ncauj feem ntau yog siv rau txheej rwb thaiv tsev; ib hom - txheej txheej txaus rau tus qauv thauj dej kub, qhov siab - cov ntawv thov dej kub yuav tsum muaj txheej txheej rwb thaiv tsev (piv txwv li, polyurethane ua ke nrog silicate fibers) los txhim kho cov cua sov.
Lub casing sab nrauv muab kev tiv thaiv cov qauv thiab los ntawm peb hom: High-Density Polyethylene (HDPE), uas muaj kev ua tau zoo tag nrho thiab siv dav; PVC, uas muab cov neeg kho tshuab siab zog ntawm tus nqi qis thiab tsim nyog rau qhov chaw ib puag ncig; thiab steel casing, uas muaj kev tiv thaiv qib siab thiab yog siv rau cov kev xav tau xws li faus ncaj qha los yog complex geological ib puag ncig. Rau cov txheej txheem dej kub cua sov, qhov kev pom zoo yog PPR cov yeeb nkab sab hauv, ib qho - txheej polyurethane rwb thaiv tsev, thiab HDPE lossis PVC txheej txheej. High-tej dej kub daim ntawv thov kev tswj hwm kev siv cov rwb thaiv tsev sib xyaw. HDPE lossis steel txheej casings raug pom zoo rau ncaj qha - faus kev teeb tsa lossis thaj chaw uas muaj cov khoom hnyav. Rau cov cua txias hauv nruab nrab lossis cov kav dej tshuaj, cov xaim hluav taws xob tuaj yeem raug teeb tsa los pab txhawb kev saib xyuas yav tom ntej. Los ntawm kev sib xyaw ua ke ntawm peb txheej txheej, PPR cov kav dej insulated ua tiav qhov sib npaug ntawm kev pabcuam lub neej, thermal rwb thaiv tsev efficiency, thiab kev tiv thaiv txhua yam, ua tau raws li cov kev xav tau ntawm ntau yam kev siv xws li lub tsev cua sov, thauj dej kub, thiab cov kav dej.
