ASTM A213 T91 Tubes Sawv Cev Ib Tug Tseem Ceeb Tshaj Plaws hauv Alloy Steel Technology, cais tawm ua lub zog ua kom zoo dua qub (CSEF) hlau.
Tsim raws li UNSICT K90901 tubes, qib qib no yog qhov yooj yim thiab hloov pauv ntawm vanadium, niobium, thiab nitrogen. Feem ntau hu ua chrome - moly t91}} kev ua kom muaj zog thiab txhim kho kev ua kom muaj zog thiab txhim kho kev ua kom muaj zog piv rau cov pa hluav taws xob
Thawj qhov txiaj ntsig ntawm ASTM A213 T91 Alloy Steel Seamless Tubes lus dag thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob ntau dua thiab kev ua haujlwm ntawm ultra- supcritical (USC) BOADRITICAL.
Cov hlab no yog tsim kom nruj raws li cov astm A213 txuj ci, nrog ASME SA213 T91 ua kev sib npaug rau boiler thiab siab lub siab cov ntawv thov. Kev siv seamless uas ua kom muaj feem ntau kev ncaj ncees hauv kev ua haujlwm dhau.
