Scope ntawm daim ntawv thov ntawm PPR pipelines
Nov 30, 2023
PPR cov kav dej yog tsim rau cov kav dej uas muaj qhov kub thiab txias ntawm -10 degree thiab 95 degree, thaum lawv tuaj yeem tiv taus kub txog 120 degree rau lub sijhawm luv luv. Qhov no ua rau nws tsim nyog rau kev siv sib txawv hauv ntau yam ntawm ib puag ncig thiab kev nyab xeeb. Tsis tas li ntawd, PPR cov kav dej kuj tuaj yeem siv rau kev faus av hauv av, thiab ntau yam kev teeb tsa hauv cov kav dej tuaj yeem pom tau los ntawm cov pob qij txha tshwj xeeb thiab flange kev sib txuas.

PPR kav, raws li cov khoom siv yeeb nkab niaj hnub, sawv tawm rau lawv cov khoom ruaj khov, kev ua tau zoo thiab ntau yam. Txawm hais tias hauv kev siv hauv tsev, kev lag luam, kev lag luam lossis kev ua liaj ua teb, PPR kav dej muab cov kev daws teeb meem kom tau raws li cov kev xav tau ntawm ntau qhov chaw. Nws cov khoom tu cev, kev tiv thaiv corrosion thiab lub zog siab ua rau nws yog ib qho ntawm cov khoom siv zoo tshaj plaws rau cov kav dej, qhia tias nws yuav ua lub luag haujlwm tseem ceeb hauv kev tsim kho thiab engineering yav tom ntej.
