inless steel valve yog ib hom valve ua los ntawm stainless hlau khoom, vim nws zoo heev corrosion kuj, siab kub zog thiab oxidation kuj, lug siv nyob rau hauv roj av, tshuaj, metallurgy, kev tsim kho thiab lwm yam lag luam. Daim ntawv no yuav txheeb xyuas cov khoom xaiv thiab kev ua tau zoo ntawm stainless hlau li qub.
Ua ntej, xaiv cov khoom siv
Cov ntaub ntawv ntawm stainless hlau li qub feem ntau yog austenitic stainless hlau, ferritic stainless hlau thiab austenitic ferritic duplex stainless hlau.
1. Austenitic stainless hlau: Austenitic stainless hlau tsuas yog muaj chromium, npib tsib xee thiab lwm yam khoom, nrog corrosion kuj zoo thiab kub kub lub zog, haum rau kub kub, siab siab thiab corrosive xov xwm tej yam kev mob. Hom austenitic stainless hlau 304, 316 thiab lwm yam.
2. Ferritic stainless hlau: ferritic stainless hlau tsuas yog muaj chromium, npib tsib xee, molybdenum thiab lwm yam ntsiab lus, nrog lub zog siab, oxidation tsis kam thiab hnav tsis kam, haum rau kub kub, siab siab thiab oxidizing nruab nrab tej yam kev mob. Hom ferritic stainless hlau 410, 420 thiab lwm yam.
3. Austenitic ferritic duplex stainless hlau: Austenitic ferritic duplex stainless hlau muaj ob theem ntawm austenitic thiab ferritic, uas integrates corrosion kuj ntawm austenitic stainless hlau thiab lub siab zog ntawm ferritic stainless hlau, thiab yog haum rau complex ua hauj lwm tej yam kev mob. Common duplex stainless hlau 2205, 2507 thiab lwm yam.
Thib ob, kev ua haujlwm zoo
Cov yam ntxwv ntawm kev ua haujlwm ntawm stainless hlau li qub yog feem ntau cuam tshuam hauv cov hauv qab no:
1. Kev tiv thaiv corrosion zoo heev: stainless hlau li qub muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv thaiv corrosion ntawm ntau yam xov xwm, txo cov nqi ntawm cov khoom siv tu thiab hloov.
2. Kev kub siab lub zog: stainless hlau valve muaj qhov kub thiab txias, tuaj yeem tswj cov khoom zoo hauv qhov kub thiab txias, haum rau qhov kub thiab txias, ua haujlwm siab.
3. Oxidation kuj: stainless hlau valve muaj oxidation zoo, uas tuaj yeem tiv thaiv corrosion ntawm oxidizing media thiab txhim kho lub neej kev pab cuam ntawm lub valve.
4. Hnav tsis kam: Stainless hlau valve muaj qhov hnav zoo, uas tuaj yeem txo qhov hnav ntawm lub valve thaum siv thiab txo cov nqi ntawm cov khoom siv tu thiab hloov.
5. Kev ua haujlwm zoo sealing: stainless hlau valve txais cov qauv sealing siab heev, muaj kev sib khi zoo, txo qhov kev pheej hmoo ntawm kev xau, thiab ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv ua haujlwm.
Nyob rau hauv cov ntsiab lus, stainless hlau valve nyob rau hauv cov khoom xaiv, feem ntau raws li kev ua hauj lwm tej yam kev mob los xaiv qhov tsim nyog austenitic stainless hlau, ferritic stainless hlau los yog austenitic ferritic duplex stainless hlau. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo yam ntxwv ntawm stainless hlau li qub, lawv muaj zoo heev corrosion kuj, siab kub zog, oxidation kuj, hnav tsis kam thiab zoo sealing kev ua tau zoo, thiab yog dav siv nyob rau hauv ntau yam kev lag luam teb.
