Txhua qhov chaw ntawm lub neej yuav ntsib kev mob taub hau. Nrog kev poob qis ntawm kev ua lag luam, ntau lub tuam txhab tsim khoom hauv tsev hauv kev lag luam steel tau ntsib kev lag luam poob. Kev nyuaj siab ntawm kev lag luam steel tau cuam tshuam rau kev siv cov khoom steel. Muaj ntau manufacturers tsis kam kaw. Lawv ntseeg ruaj khov tias kev lag luam steel yuav rov qab los rau ib hnub, yog li kev cia khoom thiab kev tiv thaiv corrosion ntawm steel khoom tau dhau los ua cov teeb meem tseem ceeb.
Hlau tsis zoo li lwm yam khoom. Nws yog ib qho nyuaj los lav tias nws yuav tsis corrode thiab xeb thaum lub sij hawm. Cov tub lag luam txhawj xeeb heev tias ib zaug corrosion tshwm sim, lawv yuav tsis tsuas yog tos rau hnub thaum lub lag luam rov qab los, tab sis kuj muag tsis tau ntawm tus nqi qis. Kuj tseem muaj ntau txoj hauv kev los tiv thaiv corrosion ntawm cov hlau, xws li cov khoom siv sacrificial anode anti-corrosion, sacrificial cathode tiv thaiv hlau los tiv thaiv corrosion, thiab lwm yam. Nws kuj tseem muaj cov txheej txheem tiv thaiv corrosion rau kev sib cais, kev sib cais ntawm huab cua los tiv thaiv oxidation. cov tshuaj tiv thaiv, uas belongs rau lub cev theem ntawm anti-corrosion. Lwm txoj kev yog los ntawm kev tiv thaiv cathodic. Txoj kev no yuav tsum muaj kev tiv thaiv corrosion hauv hluav taws xob. Cathodic tiv thaiv yog ib hom kev tiv thaiv electrochemical technology. Nyob rau hauv xyoo tas los no, nws tau txais kev pom zoo los ntawm ntau cov tub lag luam rau kev saib xyuas thiab kev tiv thaiv corrosion ntawm hlau thiab tau txuas ntxiv mus rau kev lag luam.
