PB xa fittings yog dav siv nyob rau hauv lub tshav pob ntawm cov dej kub coj los siv rau hauv vaj tse, thiab nws yog ib hom khoom siv ntsuab hauv cov txheej txheem tsim, siv thiab siv.
Hauv thawj qhov chaw, pb yog hom polymer, uas muaj qhov zoo ntawm kev tiv thaiv ntsuab. Yog li ntawd, nws tsis yooj yim rau cov leeg pb los tsim cov nplai, qhov hauv sab hauv, thiab yuav tsis pollute qhov nruab nrab uas yog thauj. Qhov thib ob, vim yog lub hauv paus ntawm lub cev thiab lub zog thermodynamic, cov khoom siv ntawm pb yeeb nkab haum yog khov kho, muaj kev sib zog ua haujlwm zoo heev, me me coefficient ntawm thermal conductivity, siab hydrostatic zog, thiab zoo yooj. Ib zaug dua, PB xa khoom fittings muaj cov yam ntxwv ntawm kev sib txuam thiab kev pom zoo, yooj yim rau nruab thiab thauj, thiab kev sib txuas thiab txhim khu kev qha.
Dhau li ntawm, PB yeeb fittings yog lub cev nyhav, zoo yooj yim, yooj yim siv, 1/20 ntawm galvanized steel yeeb nkab, yoojyim kov, cov khoom muag, thiab yam tsawg kawg ntawm txoj hlua khi ntawm 6D.
