Lub ntsiab txhais ntawm polyethylene pipeline

Cov kav dej polyethylene muaj ntau yam kev siv, los ntawm cov kav me me daj siv rau cov pa roj carbon monoxide mus rau cov kav dej tuab tuab nrog txoj kab uas hla ntawm 48 ntiv tes siv rau cov kav dej hauv nroog thiab hauv nroog. Kev siv cov kav dej loj-ntev hollow phab ntsa los hloov cov kav dej los nag thiab lwm cov kav dej phwj tuaj loj hlob sai. Nws muaj kev tiv thaiv zoo rau feem ntau ntawm cov khoom siv hauv tsev thiab kev lag luam. Qee hom tshuaj muaj peev xwm ua rau cov tshuaj corrosion, xws li corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), thiab halogenated hydrocarbons; (Carbon tetrachloride)&# 160; Nws muaj cov hluav taws xob zoo heev, tshwj xeeb tshaj yog cov rwb thaiv tsev dielectric zog, ua rau nws zoo heev rau cov xov hlau thiab cables. Cov qib nruab nrab mus rau qib siab molecular hnyav muaj qhov cuam tshuam zoo heev, txawm tias nyob hauv chav tsev kub thiab qis qis ntawm -40F.
