Stainless hlau li qub yog zoo heev rau siv nyob rau hauv corrosive pipelines thiab chav pipelines. Lawv muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, kub tsis kam thiab siab ua haujlwm siab. Lawv feem ntau yog siv rau hauv cov kav dej corrosive hauv cov nroj tsuag tshuaj, thiab cov kav dej hauv cov kais dej lossis cov nroj tsuag zaub mov. Cov pa roj carbon steel li qub tsis muaj kev tiv thaiv corrosion thiab tsuas yog siv tau hauv cov kav dej nruab nrab uas tsis muaj corrosive xws li chav, roj, dej, thiab lwm yam. Tus nqi ntawm cov pa roj carbon steel li qub yog qis dua li cov hlau tsis muaj steel, yog li feem ntau tsis muaj corrosive chav thiab lwm yam. cov kav dej yog siv. Carbon steel yog siv, thiab stainless hlau li qub thiab lwm yam ntaub ntawv yog siv rau corrosion. Cov hauv qab no yog cov lus piav qhia luv luv ntawm daim ntawv thov xaiv ntawm stainless hlau inter-valve thiab carbon steel rooj vag valve los ntawm NSW Valve:
1 Dab tsi yog vim li cas rau cov pa roj carbon steel valve
Carbon steel rooj vag valve yog ib qho kev lag luam valve, uas yog siv dav hauv roj av, tshuaj lom neeg, chaw nres tsheb fais fab thiab lwm yam lag luam. Nws muaj qhov zoo ntawm automation, kev ua haujlwm yooj yim, thiab lub neej ua haujlwm ntev, tab sis thaum siv
Thaum lub sij hawm tus txheej txheem, vim muaj kev cuam tshuam ntawm nws tus kheej los yog lwm yam tseem ceeb, carbon steel rooj vag valve yuav xau. Yog li, dab tsi yog vim li cas rau cov pa roj carbon steel rooj vag valve? Cov ntsiab lus tseem ceeb yog raws li nram no
vim li cas.
1. Qhov kev ua haujlwm qis qis ntawm lub nplhaib zoo li lub nplhaib sib khi ua rau lub tog hauv ncoo ntawm cov pa roj carbon steel rooj vag valve. Ntev npaum li lub rooj vag valve ntawm lub hom loj yog xaiv, qhov zoo ntawm cov khoom seem feem ntau zoo dua, yog li kev ua tiav ntawm lub nplhaib sealing yuav tsis qis.
1. Kev tsim khoom tsis ruaj khov thiab kev ua haujlwm tsis zoo ua rau muaj kev nkag mus rau sab hauv ntawm lub qhov rooj valve. Lub rooj vag valve muaj qhov xav tau siab ntawm qhov chaw ua haujlwm. Yog tias qhov kub thiab txias ib puag ncig tsis ruaj khov thiab qhov kev hloov pauv loj dhau lawm, qhov cuam tshuam ntawm lub nplhaib sealing yuav loj, uas yooj yim heev. Deformation tshwm sim, uas thaum kawg ua rau valve to.
3. Kev saib xyuas tsis zoo ntawm lub valve ua rau lub tog hauv ncoo ntawm lub rooj vag valve. Qee tus neeg ua haujlwm tsis ntxuav lub sealing nto ntawm lub nplhaib sealing thaum overhauling lub valve. Lub hav zoov ntawm impurities yuav cuam tshuam rau kev ua haujlwm ntawm lub valve. Nyob rau hauv lub sij hawm ntev, lub sealing nto yuav raug khawb, uas yuav ua rau valve to.
4. Lub nplhaib sib khi zoo li lub nplhaib ntawm cov ntaub thaiv npog ua rau lub rooj vag valve los rau lub sijhawm ntev. Nyob rau hauv kev cuam tshuam ntawm nruab nrab, lub nplhaib sealing yog yooj yim corroded. Yog tias qhov corrosion mus txog ib theem, lub nplhaib sealing yuav raug tshaj tawm, kom lub valve xau.
5. Lub valve lub cev tsis zoo. Yog hais tias lub valve lub cev muaj teeb meem xws li pores, slag inclusions, tawg, xuab zeb qhov, thiab lwm yam, ces lub rooj vag valve yog feem ntau mus rau sab nraud to thaum siv.
Nyob rau hauv luv luv, qhov to ntawm carbon steel rooj vag valve yog ib qho teeb meem tshwm sim. Yog tias muaj cov dej xau, nws yuav ua rau muaj kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm, yog li nws yog qhov yuav tsum tau nrhiav qhov laj thawj thiab daws qhov teeb meem raws sijhawm.
4 Yuav ua li cas xaiv ib tug txhim khu kev qha stainless hlau valve
Qhov sib txawv ntawm cov pneumatic pob valve zoo tib yam, hluav taws xob npauj npaim valve thiab lwm yam khoom siv valve, lub rooj vag tiam tsis tas yuav kho qhov ntws ntawm cov kua nruab nrab qhuav, tab sis ua raws li qhov qhib tag nrho thiab tag nrho txiav tawm hauv cov kav dej.
Lub rooj vag hloov tau siv. Yog li ntawd muaj ntau ntau stainless hlau rooj vag li qub nyob rau hauv kev ua lag luam, yam khoom twg yog txhim khu kev qha? Cov yam ntxwv ntawm stainless hlau rooj vag li qub
Stainless hlau yog ua los ntawm stainless hlau. Qhov zoo ntawm stainless hlau thiab kev kho deg thiab quenching thiab tempering hloov ua rau cov hlau tsis muaj steel zoo los tiv thaiv corrosion thiab zoo zoo.
Abrasion, ruaj heev. Yog li ntawd, stainless hlau rooj vag valve feem ntau yog siv los tswj cov ndlwg ntawm cov tshuaj, thiab nws zoo sealing thiab corrosion kuj ua rau nws tsis yooj yim rau eroded thiab ntxuav los ntawm nruab nrab.
Tus txiv neej kub thiab siab siab kuj tuaj yeem ua kom muaj kev sib khi zoo. Qhov twg stainless hlau rooj vag valve zoo dua
Nws tau hais tias stainless hlau rooj vag valve yog tsuas yog ib qho khoom siv valve, tab sis nws yog qhov ua tau zoo heev. Piv txwv li, yog tias qhov kev xaiv ntawm lub rooj vag valve yog qhov tsis ncaj ncees lawm, tej zaum yuav muaj teeb meem tshwm sim, yog li tsis txhob ua
Stainless hlau rooj vag valve yuav tsum raug kuaj xyuas ua ntej tawm hauv lub hoobkas. Thaum yuav lub valve, tus neeg siv khoom yuav tsum tau txiav txim siab ntau yam uas lub valve yuav tsum tau tiv thaiv ua ntej los xaiv cov qauv tsim nyog thiab cov lus qhia tshwj xeeb.
Cov tuam txhab lag luam tsis tu ncua yog nruj dua thiab muaj tseeb hauv kev ntsuas siab, yog li txawm tias nws yog qhov zoo ntawm lub valve, kev pabcuam lub neej, kev ua haujlwm zoo, lossis kev nyab xeeb kev ua haujlwm.
Nws yog qhov tseem ceeb tshaj plaws los xaiv cov chaw tsim khoom tsis tu ncua thiab txhim khu kev qha, thiab cov khoom lag luam ntawm cov tuam txhab tsis tu ncua (NSW Valve) muaj kev nyab xeeb dua.
Txhua tus neeg siv khoom muaj cov kev xav tau sib txawv rau cov rooj vag stainless hlau qhuav. Hais txog tus nqi, qhov zoo thiab kev tiv thaiv hom, cov tuam txhab sib txawv qee zaum muaj qhov sib txawv pom tseeb. Yog li ntawd, kev xaiv ntawm manufacturers yuav tsum xav txog ntau yam.
