Cov khoom siv ua ntej kev xaiv rau ntsug multistage nqus yog nyob ntawm lub twj tso kua mis txoj kev ua haujlwm thiab cov khoom ntawm cov kua dej tau tso tawm. Hauv qab no yog qee cov neeg Multistage cov multistage twj tso kua mis cov khoom siv khoom, nrog rau lawv cov yam ntxwv thiab muaj feem xyuam nrog cov xwm txheej:
1. Stainless hlau:
Khoom siv:Austenitic stainless hlau xws li 304 (0cr18ni9) thiab 316 (0cr18ni) yog siv ntau.
Nta:Zoo tshaj plaws corrosion, tshwj xeeb haum rau cov kua dej muaj cov khoom siv cov khoom siv me me.
Cov Ntawv Thov:Siv dav hauv cov dej mov, kev txhawb nqa kev lag luam, kev thauj khoom ua kua tsheb thauj khoom, kev kho kom dej, thiab lwm daim teb.
2. Nrha Hlau:
Khoom siv:Grey cam khwb cia hlau (HT) thiab cov hlau ductab (Qt) yog ob hom sib txawv.
Nta:Cam khwb cia hlau muaj cov khoom zoo heev thiab hnav tsis kam, tab sis kuj tsis zoo corrosion tsis kam.
Cov Ntawv Thov:Feem ntau siv rau kev nqus dej kom huv lossis cov medosive corrosive.
3. Nrab Steel:
Khoom siv:Thaum siab tshaj li 1.6 MPa, siab - Cov kabmob seem yog feem ntau ua los ntawm cam khwb cia steel, xws li ZG230-450.
Nta:Cam khwb cia steel muaj lub zog siab thiab hnav tsis kam, ua rau nws haum rau high {} {1} {{free {{} Cov ntawv thov.
Daim Ntawv Thov:Feem ntau siv nyob rau hauv kev lag luam tshuab uas yuav tsum tau qhib siab.
4. Cov Hlau Txheej Txheem Hlau:
Khoom siv:Cov Qauv Txheej Txheem Carbon Txheej Txheem Hlau (xws li Q235) thiab siab- Zoo carbon qauv hlau (xws li 45 hlau).
