Cov qauv hlau tau siv dav hauv cov tuam tsev, txuas hniav, thiab kev lag luam vim lawv lub zog siab, kav ntev, thiab lub teeb yuag. Txawm li cas los xij, ntev -}}}}} Kev siv tsis raug cai tuaj yeem ua rau corrosion, deformation, thiab txawm txheej txheem kev ua tsis tiav. Yog li ntawd, kev saib xyuas kev tshawb fawb yog qhov tseem ceeb heev kom ncua lub neej ntawm cov qauv steel.
Kev tu thiab tshuaj xyuas yog cov kev ua haujlwm ntawm kev kho vaj tse. Hmoov av, roj, thiab corrosive cov tshuaj tau yooj yim ntxiv rau saum npoo ntawm cov qauv hlau. Nws raug nquahu kom ntxuav cov qauv hlau nrog ib daim ntaub mos muag txhua rau lub hlis, kom tsis txhob nyob ntawm ntug hiav txwv uas muaj qhov sib zog ua kom zoo nrog cov khoom tawv. Welds, pob qij txha, thiab bolts yuav tsum tau kuaj xyuas kom xoob lossis xeb, thiab cov khoom siv puas yuav tsum tau ua kom nruj lossis hloov pauv sai.
Anti - kev kho corrosion yog qhov tseem ceeb. Cov qauv tshiab steel yog feem ntau coated nrog ib tug primer thiab topcoat, tab sis cov txheej txheej no tuaj yeem ua rau lub sijhawm. Yog pom tias xeb, xuab zeb thiab ntxuav lawv ua ntej rov ua dua tshiab - corrosion xim. Rau cov cheeb tsam corroded hnyav, ib nrab ntawm cov anti- corrosion cov khoom siv lossis kev sab laj nrog tus kws tshaj lij kws tshaj lij yog pom zoo. Tsis tas li ntawd, nquag muab tshuaj tiv thaiv anti {{{}} xeb siv quav ciab lossis tshuaj tiv thaiv tuaj yeem txhim kho cov hlau tiv thaiv ib puag ncig.
Ib puag ncig tswj kuj tseem ceeb heev. Zam kev ntev ntev ntawm cov qauv steel rau acidic lossis alkaline kua, seawater, dej hiav txwv. Nyob rau hauv ib puag ncig vaum, cov khoom siv dehumidification lossis kev ua pa tshuab tuaj yeem ntsia tau. Cov txheej txheem sab nraum zoov yuav tsum tau nruab nrog kev tawm tsam lossis los nag thaiv kom txo cov dej nag ncaj los nag.
Thaum kawg, kev txij nkawm yog qhov tseem ceeb. Nws raug nquahu tias ib qho kev ua yeeb yam ua ib qho kev tshuaj ntsuam xyuas txhua xyoo, tsom mus rau cov kev tiv thaiv tseem ceeb rau kev nyab xeeb thiab kev ua tau zoo. Los ntawm kev saib xyuas kev tshawb fawb, cov qauv steel tsis yog tswj lawv tus tab sis kuj muaj zog thiab ruaj khov, ua haujlwm ntev}} 60 thib muaj zog ua haujlwm.
