Kev tiv thaiv corrosion ntawm lub cev, feem ntau yog qhov kev xaiv ntawm cov khoom siv. Txawm hais tias kev tiv thaiv corrosion ntawm cov ntaub ntawv yog nplua nuj, tab sis tuaj yeem xaiv qhov tsim nyog, kuj tsis yog ib qho yooj yim ntawm cov khoom, vim hais tias corrosion ntawm cov teeb meem yog complex, piv txwv li sulfuric acid nyob rau hauv concentration tsawg Shi on steel muaj loj ntawm corrosion poj niam txiv neej, concentration siab Shi yog. ua rau cov hlau ua cov zaj duab xis passivation, tuaj yeem tiv thaiv corrosion; hydrogen tsuas yog nyob rau hauv kub kub siab siab Xia tsuas yog tso tawm nyob rau hauv steel ntawm corrosion kev sib deev muaj zog, chlorine nyob rau hauv qhuav lub xeev Shi corrosion kev ua tau zoo thiab yog tsis zoo li, thiab yuav tsum humidity Shi corrosion kev ua tau zoo muaj zog, ntau yam khoom tsis tuaj yeem nrog. Xaiv lub valve lub cev cov khoom teeb meem, kuj yog nyob rau hauv tsis tsuas yog cov teeb meem corrosion, thiab muaj peev xwm ua siab ntev thiab kub yuav tsum tau txiav txim siab, rational, economical, thiab yooj yim nws yog mus yuav, thiab lwm yam. Yog li koj yuav tsum ua tib zoo.
Qhov thib ob, kev ntsuas hauv ob sab phlu, xws li cov hlau lead-lined, lined nrog aluminium, lined yas, xws li cov roj hmab ntuj thiab hluavtaws roj hmab hauv ob sab phlu. Media daim ntawv tso cai, nws' yog txoj kev txuag.
Ntxiv dua thiab, nyob rau hauv cov ntaub ntawv ntawm tsis tshua muaj siab, kub, non-metallic valve lub cev cov ntaub ntawv, feem ntau yuav ua tau zoo heev tiv thaiv corrosion.
Tsis tas li ntawd, kuj los ntawm atmospheric corrosion nyob rau sab nrauv ntawm lub valve lub cev, General steel cov ntaub ntawv rau xim tiv thaiv.
Corrosion ntawm li qub, feem ntau yog to taub raws li cov ntaub ntawv valve hauv tshuaj los yog electrochemical nyob rau hauv kev puas tsuaj ntawm ib puag ncig. Vim" corrosion" phenomenon tshwm nyob rau hauv cov hlau spontaneous kev sib cuam tshuam nrog ib puag ncig, yuav ua li cas cov hlau thiab ib puag ncig ib puag ncig yog cais los yog ntau dua siv cov khoom uas tsis yog-metallic composite, yog lub hom phiaj ntawm corrosion.
Valve lub cev (suav nrog npog), tuav feem ntau ntawm qhov hnyav ntawm lub valve, thiab nyob rau hauv kev sib cuag nrog cov xov xwm, yog li siv li qub, feem ntau pib los ntawm lub valve lub cev khoom.
