SA213 T91 Kub Tiav Tube
GNEE tshwj xeeb hauv kev tsim khoom ntawmASTM A213 T91 seamless steel kavuas ua tau raws li thoob ntiaj teb specifications. Nws muaj cov khoom siv kho tshuab zoo heev thiab ntau yam kev siv. Ua ke nrog cov txiaj ntsig saum toj no, peb tuaj yeem muab cov khoom lag luam zoo tshaj plaws raws li cov neeg siv khoom xav tau
ASTM A213 T91 alloy steel yeeb nkab cov ntaub ntawv muaj cov pa roj carbon, manganese, phosphorus, sulfur, silicon, molybdenum thiab chromium. Cov muaj pes tsawg leeg ntawm ASTM A213 T91 seamless alloy yeeb nkab ua rau nws muaj peev xwm tiv taus thermal qaug zog, thiab muaj cua sov hloov mus thiab tsis tshua muaj thermal expansion ntawm qhov kub thiab txias, thiab tau dav siv los tsim cov kav dej uas xav tau los ntawm kev lag luam.
SA213 T91 Kub Tiav Hlau Tube yog tsim los ntawm seamless kub dov txheej txheem, uas muaj qhov zoo ntawm cov txheej txheem vuam zoo, kev ua haujlwm siab zog thiab oxidation tsis kam. SA213 T91 cov yeeb nkab kub tiav yuav tsum tau txias hauv qhov chaw hydrogen kom ntseeg tau tias qhov ci ntsa iab yuav tsis hloov vim qhov kub oxidation.
