Nws qhov sib npaug profile ua rau nws haum rau ntau yam kev lag luam tseem ceeb:
Cov Khoom Siv Hluav Taws Xob & Boilers:Siv rau lub plhaub, lub taub hau, thiab lwm yam siab - khaws cov khoom hauv cov boilers, chav generators, thiab cov txheej txheem cov hlab ntsha.
Roj & Roj Kev Lag Luam:Tsim cov fractionation towers, separators, scrubbers, thiab cia tso tsheb hlau luam (xws li LPG) qhov twg cov khoom yuav tsum tau tiv thaiv sab hauv siab thiab thermal cycling.
Chemical & Petrochemical Nroj Tsuag:Siv nyob rau hauv reactors, tshav kub exchangers, thiab kab uas lis ntau yam tshuaj nyob rau hauv nruab nrab siab thiab qis rau ambient kub.
Kev tsim hluav taws xob:Siv nyob rau hauv boiler nruas, chav generators, thiab siab - cov kav dej siab nyob rau hauv ob qho tib si thermal thiab nuclear fais fab nroj tsuag.
SA-612 vs SA-516 Qib 70
SA-516 Qib 70 yog lub hom phiaj dav dav dav dav dav hlau hlau, thaum SA-612 yog siv qhov twg muaj zog dua lossis qis dua qhov xav tau.
| Feature | SIB-612 | SA-516 Gr . 70 |
|---|---|---|
| Qib Siab | Siab (YS Ntau dua lossis sib npaug rau 345 MPa) | Nruab nrab (YS Ntau dua lossis sib npaug rau 260 MPa) |
| Tsim Advantage | Tso cai rau thinner, sib zog hlab ntsha phab ntsa hais | Feem ntau siv nyob rau hauv thicker -walled, dav- lub hom phiaj nkoj |
| Qhov kub thiab txias | Tshwj xeeb tsim los rau nruab nrab thiab qis kub, nrog guaranteed toughness ntawm -40 degree | Haum rau qhov nruab nrab thiab qis qis, tab sis kev ntsuam xyuas cuam tshuam yuav tsum tau txiav txim tshwj xeeb |
| Weldability | Zoo heev, tab sis yuav tsum nruj dua tswj thiab tsim nyog WPS vim muaj zog dua; preheating tej zaum yuav xav tau rau cov seem tuab | Zoo heev thiab ntau zam txim rau weld; preheating feem ntau tsis tas yuav tsum tau |
| Qhov siab tshaj plaws Thickness | Txwv rau 25 hli (1 nyob rau hauv.) los ntawm tus qauv, tab sis qee tus neeg muag khoom muab cov tuab dua | Muaj nyob rau hauv ntau yam, yooj yim mus txog 200 mm |
| Tej kev siv | Lub teeb yuag lossis txias - cov hlab ntsha siab, LPG tanks, cov khoom siv tshuaj | Cov hlab ntsha dav dav, cov tso tsheb hlau luam loj, tuab- cov phab ntsa boilers thiab cov cua kub exchangers |
