Vim li cas thiaj xaiv SA 285 GR.C?

SA 285 Gr.Cyog qhov qis- mus rau nruab nrab- lub zog carbon steel phaj siv tsuas yog rau cov hlab ntsha siab thiab lwm yam siab- muaj cov khoom siv ua haujlwm ntawm qhov kub thiab txias thiab nruab nrab. Nws tau teev nyob rau hauv ASME Tshooj II (SA-285) thiab sib raug rau ASTM A285 Qib C, qhov twg Qib C sawv cev rau lub zog siab tshaj plaws ntawm peb qib (A, B, C) hauv cov lus qhia no.

Nws muaj nuj nqis rau nws qhov zoo weldability thiab formability, ua rau nws tsim nyog rau fabricating tso tsheb hlau luam, nkoj plhaub, taub hau, thiab tej yam kub exchanger Cheebtsam nyob rau hauv kev lag luam, petrochemical, thiab txheej txheem daim ntawv thov uas ntau alloyed steels tsis tas yuav tsum tau.

Mechanical Properties ntawm ASME SA285 Gr C

daim ntawv thov

Cov hlab ntsha siab:

Cov phaj no feem ntau yog siv rau hauv kev tsim cov hlab ntsha, xws li boilers, tso tsheb hlau luam, thiab cov reactors, uas lawv tuaj yeem tiv taus siab thiab kub. Lawv zoo weldability thiab formability ua rau lawv tus nqi -kev xaiv zoo rau lub plhaub, taub hau, thiab lwm yam siab- muaj cov khoom nyob rau hauv ntau yam kev lag luam sectors.

Thaum tshav kub kub exchangers:

Lawv tsim nyog rau kev tsim qee yam ntawm cov khoom siv hluav taws xob, tshwj xeeb tshaj yog cov kev ua haujlwm ntawm qhov nruab nrab kub. Lawv cov thermal conductivity zoo thiab muaj peev xwm ua tau yooj yim tsim rau hauv cov plhaub thiab cov tubesheets ua rau lawv qhov kev xaiv ua tau zoo rau ntau yam dav dav - lub hom phiaj kev siv hluav taws xob hloov pauv.

Cia tank:

ASME SA 285 Qib C daim hlau yog dav siv hauv kev tsim cov tank cia rau cov kua thiab roj. Lawv feem ntau tau teev tseg rau lub tank tuav cov khoom siv roj, tshuaj, dej, thiab lwm yam uas tsis yog -corrosive lossis me me corrosive media hauv refineries, tshuaj nroj tsuag, thiab cov chaw tsim khoom.

Cov khoom siv txheej txheem:

Cov paib no yog siv rau hauv kev tsim cov khoom siv, nrog rau cov kav dej, li qub, thiab fittings, hauv kev lag luam chemical thiab petrochemical. Lawv feem ntau raug xaiv rau lawv txoj kev ntseeg siab thiab kev yooj yim ntawm kev tsim khoom hauv nruab nrab - cov txheej txheem siab.

Kev tsim hluav taws xob:

Lawv tau ua haujlwm nyob rau hauv kev tsim cov khoom siv hauv cov chaw tsim hluav taws xob, xws li qee qhov chaw boiler, chav generators, thiab cov cuab yeej pabcuam siab. Lawv lub zog thiab kav ntev ua rau lawv haum rau ntau yam uas tsis yog - daim ntawv thov kev pabcuam hnyav hauv cov chaw tsim hluav taws xob.

Hu rau tam sim no

Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.

SA 285 Gr.C yog dab tsi?

SA 285 Gr.C yog qhov qis- mus rau nruab nrab- lub zog carbon steel phaj rau welded siab hlab ntsha, tau pom zoo los ntawm ASME (SA-285) thiab sib xws rau ASTM A285 Qib C. Nws yog siv feem ntau rau qis / nruab nrab siab thiab kub kev pab cuam.

Dab tsi yog cov khoom tseem ceeb ntawm SA 285 Gr.C?

Nws muab cov weldability zoo, zoo formability, thiab nruab nrab lub zog, nrog rau tus nqi -kev ua tau zoo rau cov uas tsis yog - mob hnyav.

Dab tsi yog qhov kev thov ntau yam rau SA 285 Gr.C?

Nws yog feem ntau siv rau lub siab ntawm lub plhaub thiab lub taub hau, lub tank cia, cov khoom siv hluav taws xob sib hloov / cov ntaub ntawv (cov kev pabcuam nruab nrab), thiab cov txheej txheem dav siv hauv tshuaj, petrochemical, thiab cov nroj tsuag muaj kev lag luam.

Cov txheej txheem vuam zoo li cas rau SA 285 Gr.C?

Cov txheej txheem xws li SMAW, GMAW, FCAW, thiab SAW feem ntau haum. Preheat los yog post-weld heat treatment (PWHT) tej zaum yuav xav tau rau cov phaj tuab lossis cov pob qij txha nruj heev.

Puas yog SA 285 Gr.C xav tau kev kho cua sov?

Nws feem ntau muab rau hauv raws li - dov los yog normalized mob. PWHT tsis tas yuav tsum tau tab sis tej zaum yuav raug teev raws li thickness, vuam txheej txheem, thiab tsim cov cai (xws li, kev ntxhov siab).

SA 285 Gr.C piv rau SA 285 Gr.A thiab Gr.B li cas?
