Petroleum asphalt, raw khoom dav, tus nqi qis. Txawm li cas los xij, kev ua haujlwm tsis zoo, tsis yooj yim rau kev lees paub zoo, muaj kuab paug ib puag ncig loj.

Coal tar epoxy, yooj yim rau kev khiav lag luam, tab sis lub sij hawm ntev npog txheej yog kho los ntawm ib puag ncig kev cuam tshuam, haum rau kev ua hauj lwm teb, cov nram qab no 10 ℃ nyuaj kev tsim kho.

Anticorrosive txias tapes, yooj yim rau kev khiav lag luam, tab sis me ntsis zuj zus adhesion, tsis tshua muaj dej tsis kam, tsis muaj zog, qhov loj ib puag ncig.

Epoxy hmoov corrosion, electrostatic spraying, anti-corrosion khoom nrog tib hom raj frit zoo, muaj zog sib txuas, epoxy hmoov tab sis dej tsis zoo (siab dej nqus, ncav cuag 0.83%), rau cathodic tiv thaiv tsim coj ib co teeb meem. Cov khoom siv hauv tsev yuav tsum tau ua, kev ua haujlwm nyuaj, nyuaj rau kev tswj kom zoo.

3PE shrink cov ntaub ntawv, sealing muaj zog pipeline corrosion, siab mechanical zog, dej kuj muaj zog, ruaj khov zoo, yooj yim siv, siv tau, thiab tsis txhob ua phem rau ib puag ncig. PE tsis tshua muaj dej nqus (tsawg dua 0.01%), nrog rau lub zog siab epoxy, kub yaj nplaum nplaum PE tsis muaj dej nqus thiab yoog raws, kev ntseeg siab corrosion siab, qhov tsis zoo yog: Piv nrog rau lwm cov khoom siv kho cov nqi siab.

Features txias tapes thiab 3PE shrink bands yog: rau txhua yam ntawm cov yeeb nkab txheej khoom ntawm lub cev, thaum lwm txoj kev yog siv rau tib yam los yog ze rau cov yeeb nkab txheej khoom lub cev.
