ASTM A234 WPB Eccentric Reducer Nto Kho Kho
Txhawm rau tiv thaiv xeb thaum thauj thiab khaws cia, carbon steel reducers feem ntau raug kho nrog cov hauv qab no:
Dub Painting / Varnish:Txoj kev siv feem ntau siv los tiv thaiv xeb ib ntus.
Anti- xeb Roj:Kev tiv thaiv lub teeb uas yooj yim los ntxuav ua ntej kev teeb tsa.
Kub Dip Galvanized:Siv rau qhov chaw ntub dej heev lossis siab -corrosion ib puag ncig.
3LPE / FBE Txheej:Cov txheej txheem tshwj xeeb rau cov kav dej hauv av.
Txhaj tshuaj Blasting:Tshem tawm cov nplai zeb los tsim ib qho chaw du, zoo tagnrho rau cov txheej tom ntej lossis pleev xim.
ASTM A234 WPB Eccentric Reducer Kev Ntsuas Kub
ASTM A234 WPB tshwj xeeb tsim raunruab nrab thiab siab -kev pabcuam kub.
Pom zoo Temperature Range:
−29∘C(−20∘F) rau 425∘C(800∘F).
Cov ntsiab lus tseem ceeb:
Thaum siv rau lub sijhawm ntev ntawm qhov kub thiab txias saum toj no425 degree, cov carbides hauv carbon steel yuav hloov mus rau graphite, uas tuaj yeem ua rau txo qis zog.
