Daim ntawv thov:
Cov hlab ntsha siab:
Cov phaj no feem ntau yog siv rau hauv kev tsim cov hlab ntsha, xws li boilers, tanks, thiab reactors, uas lawv tuaj yeem tiv taus siab thiab kub.
Thaum tshav kub kub exchangers:
Lawv tsim nyog rau kev tsim cov khoom siv hluav taws xob sib txawv, vim lawv muaj cov khoom siv hluav taws xob zoo thiab ua rau corrosion.
Cia tank:
ASME SA 285 Qib C Siab Vessel Carbon Steel Phaj tuaj yeem siv rau hauv kev tsim cov tank cia rau cov kua thiab roj.
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.
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 cov tshuab hluav taws xob thiab cov turbine casings.
Qhov zoo:
Zoo Weldability & Formability:
Ib qho yooj yim los txiav, duab, thiab vuam siv cov txheej txheem txheej txheem, txo kev tsim khoom nyuaj.
Lub zog nruab nrab:
Muab lub zog tensile siab dua li Qib A thiab B, ua rau nws haum rau me ntsis xav tau qis dua - cov tshuab siab.
Corrosion Resistance:
Muab kev ua haujlwm zoo rau kev txhim kho corrosion, pitting, thiab crevice corrosion, txhim kho cov khoom siv ntev.
Kev ua haujlwm kub:
Exhibits zoo mechanical zog ntawm ob qho tib si qis thiab siab kub, zoo tagnrho rau ntau yam kev pab cuam.
Tus nqi -zoo:
Ib qho kev xaiv txhim khu kev qha thiab kev lag luam rau ntau PVQ (Pressure Vessel Quality) daim ntawv thov.
Stable Composition:
Nws cov tshuaj pleev ib ce zoo ib yam (carbon, silicon, manganese) ua kom cov khoom siv dag zog thiab kev ua tau zoo.

Dab tsi yog qhov txawv ntawm SA 285 GR C thiab SA 283 GR C?
SA 283 Gr C yog rau cov qauv dav dav thiab qis- cov tso tsheb hlau luam siab, thaum SA 285 Gr C yog rau cov hlab ntsha siab thiab cov boilers nrog kev tswj cov tshuaj nruj dua. Lawv tsis yog ib txwm hloov pauv tau vim muaj kev txwv tsis pub siv. Gangsteel daim hlau txhawb ob qho tib si nrog cov ntawv pov thawj.
SA 285 Qib C sib npaug yog dab tsi yog lub zog tawm los ntawm SA 285 GR.C?
ASME SA 285 Gr C sib npaug suav nrog ASTM A285 Qib C, EN P235GH, DIN HI, JIS SPV235, BS 161-360A, GB Q245R, nrog cov txiaj ntsig ~ 205-235 MPa rau cov nkoj uas tsis tshua muaj siab.
Dab tsi yog qhov txawv ntawm SA 285 GR C thiab A36?
A285 Qib C muaj zog tensile qis mus rau nruab nrab ntawm 380 txog 515 MPa, thaum lub zog tensile ntawm A36 cov khoom muaj nyob nruab nrab ntawm 400 txog 500 Mpa. Qhov no yog vim qhov txawv ntawm lawv cov tshuaj muaj pes tsawg leeg.
Lub zog tawm los ntawm SA 285 GR.C yog dab tsi?
Qhov tsawg kawg nkaus tawm lub zog rau SA 285 Qib C steel yog 30 ksi (205 MPa), nrog lub zog tensile xws li 55-75 ksi (380-515 MPa), ua rau nws muaj zog tshaj ntawm SA 285 qib (A, B, thiab C). Cov khoom siv no feem ntau yog siv rau fusion-welded boilers, cov hlab ntsha siab, thiab cov tso tsheb hlau luam, feem ntau muab rau hauv qhov xwm txheej zoo li dov.
Dab tsi kub thiab siab tej yam kev mob yog SA 285 Gr.C haum rau?
Nws feem ntau yog siv nyob rau hauv qis - mus rau nruab nrab - siab thiab kub kev pab cuam. Nws tsis pom zoo rau siab - kub, siab - siab, los yog ib puag ncig corrosive heev.
Dab tsi yog cov kev siv ntawm SA 285 Gr.C?
Nws yog feem ntau siv rau lub siab ntawm lub plhaub, lub tank cia, cov khoom siv hluav taws xob sib hloov, cov khoom siv boiler, cov txheej txheem cov cuab yeej, thiab cov khoom siv dav dav.
Dab tsi yog cov yam ntxwv tseem ceeb ntawm SA 285 Gr.C?
Nws muaj qhov zoo weldability, formability, thiab machinability, nrog rau nruab nrab lub zog thiab nqi -effectiveness. Nws yog tsim los rau kev txhim kho kev ua tau zoo nyob rau hauv uas tsis yog - ua haujlwm hnyav.
Puas yog SA 285 Gr.C xav tau kev kho cua sov?
Feem ntau, tsis xav tau kev kho cua sov tshwj xeeb. Txawm li cas los xij, kev kho cua sov ntawm kev ntxhov siab tuaj yeem siv raws li cov thickness, vuam tej yam kev mob, los yog tsim cov kev cai.
