PE cev

PE polyethylene PE yog polyethylene yas, uas yog ib tug series ntawm ntau yam ntawm resins tsim los ntawm ntau yam txheej txheem, nrog rau ntau yam qauv, khoom thiab siv. PE cov kav dej muaj xws li cov kav dej polyethylene nruab nrab thiab cov kav dej polyethylene siab, uas tau muab faib ua SDR11 thiab SDR17.6 series raws li phab ntsa tuab. Lub qub yog tsim rau conveying gaseous artificial gas, natural gas thiab liquefied petroleum gas, thaum lub tom kawg yog tsuas yog siv rau conveying natural gas. Piv nrog rau cov kav hlau steel, cov txheej txheem kev tsim kho yog yooj yim, thiab nws muaj qee qhov yooj. Qhov tseem ceeb tshaj, nws tsis yog siv los tiv thaiv - kev kho corrosion, uas yuav txuag tau ntau txheej txheem. Qhov tsis zoo yog tias cov khoom siv tsis zoo li cov yeeb nkab steel. Hauv kev tsim kho, kev saib xyuas tshwj xeeb yog them rau qhov kev nyab xeeb ntawm cov cua kub cua sov, thiab nws tsis tuaj yeem raug tshav ntuj hauv huab cua, thiab nws yog rhiab heev rau cov tshuaj los tiv thaiv cov dej xau ntawm cov kav dej phwj los ntawm kev puas tsuaj.
