Khoom siv homlub cev muaj zog

Ntau qhov sib txawv ntawm cov yam ntxwv ntawm qhov nruab nrab erosion yam ntxwv, uas yog cov khoom siv tshuaj thiab lawv cov concentration, atmospheric tej yam kev mob, kub, lub sij hawm, yog li yog hais tias tsis to taub qhov tseeb ntawm qhov nruab nrab, kom siv cov ntaub ntawv, xaiv cov ntaub ntawv yog nyuaj.Txawm li cas los xij, cov txheej txheem hauv qab no tuaj yeem siv los ua kev xaiv:

304 thoob plaws hauv kev siv cov khoom siv.Nyob rau hauv cov tsev muaj peev xwm tiv taus corrosion, tuaj yeem tiv taus cov khoom noj khoom noj khoom noj khoom haus nruab nrab (muaj cov kua qaub tab sis siab kub thiab cov ntsiab lus chloride tuaj yeem tshwm erosion), cov organic compounds, dyes, thiab hla ntau yam inorganic tebchaw tuaj yeem tiv taus.

304L (tsawg carbon) nrog zoo tsis kam mus rau nitric acid, thiab ruaj khov nruab nrab kub thiab concentration ntawm sulfuric acid, siv raws li ib tug ua kua thoob plaws hauv lub tank gas, siv rau cryogenic khoom (304N), tus so ntawm cov neeg siv khoom, khoom siv hauv chav ua noj, cov khoom siv hauv tsev kho mob, cov cuab yeej thauj khoom, cov khoom siv dej.

316 muaj nickel me ntsis ntau dua 304, thiab muaj 2%─3% molybdenum, corrosion tsis kam tshaj hom 304, yog kev pom zoo ntawm cov ntsiab lus tshwj xeeb ntawm kev yaig los ntawm chloride media.316 tau siv los ua kev txhim kho sulphite pulp tshuab, vim nws yog cov khoom siv sulfate ruaj khov.Tsis tas li ntawd, nws siv tau nthuav dav los tswj cov khoom siv tshuaj lom neeg ntau hauv kev lag luam kev lag luam.

317 muaj 3% -4% molybdenum (cov qib siab hauv cov koob no kuj tau txais), thiab muaj ntau dua 316 hom chromium, muaj kev ua haujlwm siab dua rau pitting corrosion thiab crevice corrosion kev ua tau zoo.

430 qis dua cov ntsiab lus ntawm 304 alloy, yog siv nyob rau hauv ib qho chaw sov so dai kom zoo nkauj nrog polished siv heev, kuj tuaj yeem siv nitric acid thiab khoom noj khoom haus.

410 muaj peb qhov kev siv dav dav ntawm cov hlau tsis muaj hlau hauv cov ntsiab lus qis tshaj plaws, koj xav tau lub zog thiab corrosion kuj nrog cov khoom siv siab load-cov kabmob siv, xws li cov khoom siv.410 nyob rau hauv ib qho chaw sov so, dej, roj thiab tshuaj lom neeg cov khoom nyob rau hauv cov xov xwm muaj ntau nruab nrab corrosion kuj.

2205 dua li 304 thiab 316 superior, vim hais tias cov qauv ntawm nws cov yeeb nkab chloride kev nyuaj siab corrosion cracking muaj lub zog siab los tiv thaiv.
