SB450 siab steel phaj kev ua tau zoo
SB450 boiler phaj yog carbon steel phaj rau Japanese txheem siab hlab ntsha, nrog lub zog siab, zoo toughness thiab zoo heev vuam kev ua tau zoo.
SB450 boiler phaj muaj qhov zoo tshaj plaws weldability, yooj yim rau vuam, thiab muaj kev ruaj khov welded sib koom ua haujlwm. Nyob rau tib lub sijhawm, SB450 siab hlab ntsha hlau tuaj yeem tswj kev ua haujlwm ruaj khov hauv ntau yam kev tshaj tawm corrosive.
SB450 nkoj phaj yog dav siv hauv roj av, tshuaj, chaw nres tsheb fais fab, boiler thiab lwm yam kev lag luam, tshwj xeeb yog siv los tsim cov reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks thiab lwm yam khoom siv.
