Kev ua tau zoo ntawm SPV490 boiler zoo steel phaj
SPV490 boiler phaj yog ib qho kev ua tau zoo ntawm cov qauv hlau phaj nrog zoo cuam tshuam toughness thiab tuaj yeem tswj kev ua haujlwm ruaj khov ntawm qhov kub thiab txias. SPV490 nkoj phaj muaj qhov zoo tshaj plaws weldability thiab corrosion kuj, uas yog yooj yim rau ntau yam vuam txheej txheem.
SPV490 siab lub nkoj phaj yog dav siv nyob rau hauv cov roj av, tshuaj, chaw nres tsheb fais fab, boiler thiab lwm yam lag luam los ua reactors, tshav kub exchangers, roj thiab roj tso tsheb hlau luam, liquefied roj tso tsheb hlau luam thiab lwm yam khoom thiab cov khoom. Nyob rau tib lub sijhawm, SPV490 boiler phaj kuj tsim nyog rau cov txuas hniav, cov tsev, nkoj thiab lwm qhov chaw, uas tuaj yeem ua tau raws li koj xav tau rau ntau qhov chaw ua haujlwm nyuaj thiab hnyav.
