Tam sim no, hauv cov kav dej thiab cov kav dej, cov kav dej yas tau maj mam hloov cov kav dej ib txwm muaj xws li cov kav hlau cam khwb cia thiab cov kav dej galvanized thiab ua cov kav dej loj.Piv nrog rau cov kav dej ib txwm muaj, cov kav dej yas muaj qhov zoo zoo xws li lub teeb yuag, kev tiv thaiv corrosion, tsis tshua muaj dej ntws tsis kam, txuag hluav taws xob, yooj yim thiab ceev installation, thiab tus nqi qis, thiab nyiam los ntawm cov kav dej engineering hauv zej zog.Nyob rau tib lub sijhawm, nrog kev txhim kho sai ntawm kev lag luam petrochemical thiab kev nce qib ntawm kev tsim cov tshuab yas, cov khoom siv ntawm cov kav dej yas tau nce sai heev, thiab cov khoom lag luam tau dhau los ua ntau haiv neeg.Tsis tas li ntawd, cov kav dej yas tau ua tiav txoj kev loj hlob zoo thiab kev txhim kho hauv kev tsim txoj kev xav thiab kev siv thev naus laus zis hauv kev tsim kho, thiab tau txais cov kev paub zoo tshaj plaws, uas tau txhawb nqa cov kav dej yas los tuav txoj haujlwm tseem ceeb hauv kev tsim cov dej thiab cov kav dej engineering, thiab tsim kom muaj kev txhim kho tsis tu ncua. sib.
Hauv Suav teb, feem ntau ntawm cov kav dej yas siv hauv cov kav dej feem ntau suav nrog PVC-U cov kav dej, PP-R kav, aluminium-yas composite kav (PAP), steel-yas composite kav (SP), HDPE kav, thiab lwm yam. HDPE yeeb nkab tsuas yog tshwm sim hauv khw hauv ob xyoo dhau los.Nws txais cov cuab yeej tsim khoom siab heev thiab cov cuab yeej technology thiab yog tsim los ntawm kub extrusion.Nws muaj cov yam ntxwv ntawm corrosion kuj, du sab hauv phab ntsa, tsis tshua muaj dej tsis kam, siab zog, zoo toughness thiab lub teeb yuag.
Tom qab cov kav dej PVC-U, HDPE yeeb nkab tau dhau los ua qhov thib ob feem ntau siv cov yeeb nkab yas hauv ntiaj teb.Tam sim no, nruab nrab lossis siab ceev polyethylene kav ntawm PE80 thiab PE100 qib yuav tsum tau siv rau kev xa roj;Cov kav dej nruab nrab lossis siab ntom ntom polyethylene ntawm qib PE80 thiab PE100 feem ntau yog siv rau cov kav dej, thiab PE63 tau maj mam tshem tawm.Hais txog kev xa dej, kev loj hlob sai tshaj plaws yog PE100 pipeline system, uas xav tias yuav loj hlob ntau dua 10% hauv tsib xyoos tom ntej.
