Lub ntsiab
SA-210Cyog ib qho tshwj xeeb rau seamless nruab nrab - cov roj carbon steel boiler thiab cov leeg supertheat, txhais los ntawm tusASTM International (American Society rau kev sim thiab cov ntaub ntawv)Cov. Nws yog ib feem ntawm cov qauv A-210. Lub "C" tau qhia cov ntsiab lus carbon ntau dua thiab cov ntsiab lus manganese piv rau A-210 ib qib, ua rau muaj zog dua.
Nws thawj qhov kev tsim kho yog nyob rau hauv kev tsim kho cov rwj, thiab cov pa roj cua sov nyob rau hauv cov yeeb nkab, thiab lwm yam dej, lossis lwm yam dej nyob rau hauv kev kub siab thiab kub.
Cov yam ntxwv tseem ceeb
Khoom siv:Cov Hlau Hlau
Txheej txheem tsim khoom:Seamless (sms). Qhov no txhais tau tias cov yeeb nkab tsim los ntawm cov khoom ntim ntawm cov khoom siv welded, muab lub zog zoo dua, tshwj xeeb yog kev ntxhov siab siab.
Siab - kev pabcuam kub:Tsim los tswj nws cov kev kho zog ntawm kev nce siab kub, feem ntau txog 1000℃F (538 degree).
Weldability thiab formability:Zoo weldability thiab formability, ua rau nws haum rau fabricating ua nyuaj boiler tshuab.
Tshuaj lom neeg muaj pes tsawg leeg (%)
Cov tshuaj lom neeg muaj kuab lom yog qhov tseem ceeb hauv nws lub zog thiab siab - kub ua tau zoo.
| Lub ntsiab | Muaj pes tsawg leeg (%) |
|---|---|
| Carbon (c) | 0.35 max |
| Manganese (mn) | 0.29 - 1.06 |
| Phosphorus (p) | 0.035 Max |
| Sulphur (s) | 0.035 Max |
| Silicon (si) | Ntau dua los yog sib npaug rau 0.10 |
* Nco tseg: Cov ntsiab lus manganese ntau dua piv rau SA-210 tau qhab nia ua rau nws lub zog txhim kho. *
Cov Khoom Siv Neeg Kho Tshuab
Cov khoom txhais tau cov yeeb nkab muaj peev xwm tiv thaiv cov tshuab quab yuam.
| Ntiag tug | Tus nqi |
|---|---|
| Tensile lub zog, min | 70 ksi (485 mpa) |
| Paib muaj zog, min | 40 ksi (275 MPa) |
| Elongation, min | {{0- 30% (ntawm 2-hauv. Gauge ntev) {{0- 18% (ntawm 8-hauv. Gauge ntev) |
Cov Kev Siv Cov Ntawv Siv
Sa-210C Seamless kav yog cov khoom siv tseem ceeb hauv:
Power tiam Boilers:Phab ntsa, vov tsev, thiab cov plag tsev ntawm cov rhaub boiler uas cov dej muaj cua sov los tsim chav.
Superheaters thiab rheaters:Cov tshooj ntawm cov boiler uas txuas cua sov ntxiv kom kub siab rau kev nce qib ntawm lub turbine.
Cov tshuab hluav taws kub:Hloov chaw kub los ntawm ib qho nruab nrab mus rau lwm tus.
Muaj Nroj Tsuag Nroj Tsuag:Txhua lub tshuab uas yuav tsum tau hloov chaw nyab xeeb thiab txuag tau ntawm high - qhov siab hnyav lossis dej kub.
Qhov zoo ntawm kev siv Sa-210c
Lub zog siab:Nws cov cuab yeej ua haujlwm pub nws los tiv thaiv lub siab sab hauv pressures pom hauv cov boilers niaj hnub.
Zoo heev creep:Kev tawm tsam deformation nyob rau hauv ntev - dua kev ntxhov siab thiab kub.
Zoo oxidation tiv:Ua tau zoo nyob rau hauv chav ib puag ncig yam tsis muaj kev tshwm sim sai sai.
Tus nqi -}} Ua tau zoo:Muab cov kev sib tw zoo ntawm kev ua tau zoo thiab tus nqi rau high - kub ultrasonic cov ntawv thov.
Cov Qauv thiab Cov Lus Qhia Tshwj Xeeb
Thaum xaj lossis tshwj xeeb SA-210C, nws yog ib qho tseem ceeb kom siv cov qauv tiav:
ASTM A210 / A210M- Txheem Cov Qauv rau Seamless Nruab Nrab-} Cov leeg roj carloil boiler thiab tus supertheater leeg
Tus qauv no suav txog qhov ntev, thev taus, kev sim (hydrostatic lossis tsis yog- kev ua kom muaj zog), thiab khij qhov yuav tsum tau ua.
Kev sib piv nrog lwm qib
