FAQ
Puas yog A335 P9 welded lossis seamless yeeb nkab?
Seamless.ASTM A335 npog seamless ferritic alloy - steel yeeb nkab nkaus xwb - kub tiav lossis txias kos. Kauv-welded los yog lwm yam welded tsim tsis tso cai raws li A335. Yog tias koj xav tau welded 9Cr-1Mo yeeb nkab, qhov tseeb specification yog ASTM A691 Qib 9, ua los ntawm A387 Qib 9 phaj.
Qhov txawv ntawm A335 P9 thiab A213 T9 yog dab tsi?
Tib chemistry (9Cr-1Mo), cov khoom sib txawv thiab phab ntsa hauv paus. A335 P9 yog cov yeeb nkab nrognpephab ntsa thickness rau siab piping systems; A213 T9 yog raj nrogyam tsawg kawg nkausphab ntsa thickness, feem ntau txiav txim rau boiler thiab rhaub tsim. Qee qhov ntsuas cua sov xav tau qhov tsawg kawg nkaus - phab ntsa hauv qab - xyuas seb qhov twg koj tus qauv hu rau.
A335 P9 siv rau dab tsi?
Nws cov kev siv tseem ceeb yog refinery rhaub tubes, boiler superheater thiab reheater circuits, kub refinery txheej txheem piping (xws li kev pab cuam hydrocracker), thiab siab -kub chav kab. Nws tsis yog qhov dav - hom phiaj qib rau cov kab dej, qhov dej, lossis kev ua haujlwm.
Qhov txawv ntawm P9 thiab P91 yog dab tsi?
Ob leeg yog 9Cr-1Mo steels, tab sis P91 ntxiv vanadium thiab niobium rau lub microstructure muaj zog: yam tsawg kawg nkaus tensile 585 MPa vs 415 MPa rau P9. P91 ua haujlwm niaj hnub siab- cov chaw tsim hluav taws xob ua tau zoo; P9 yog yooj yim rau fabricate thiab dav siv nyob rau hauv refinery kev pab cuam. P91 txoj kev vuam thiab kev kho cua sov yuav tsum tau nruj dua.
Dab tsi yog qib sib npaug ntawm A335 P9?
Qhov sib npaug ze tshaj plaws yog EN 10216-2X11CrMo9-1 (cov ntaub ntawv no. 1.7386)thiab JIS G3458TIAB SA 26(tube daim ntawv: JIS G3462 STBA26). UNS tus lej rau P9 yog S50400.
