Txheej txheem cej luam
SA-210 Cyog ib tug specification rau seamless nruab nrab -lub zog carbon- steel boiler thiab superheater raj, txhais los ntawm covASTM A210 / ASME SA-210 Cov Lus Qhiatxheem. Qib "C" txhais tau tias muaj zog dua carbon-manganese steel, ua rau nws yog ib qho ntawm cov khoom siv feem ntau siv rau siab - kub thiab siab - cov ntawv thov siab hauv cov raj dej boilers.
Nws yog qhov tseem ceeb ntawm kev txhim kho ntawm SA-210A, nrog cov ntsiab lus ntawm manganese ntau dua rau kev muaj zog ntxiv.
Cov yam ntxwv tseem ceeb
Hom:Carbon Steel

Kev Siv Tseem Ceeb:Boiler tubes, superheater tubes, thiab tshav kub exchanger raj.
Qhov tseem ceeb Advantage:Lub zog zoo heev ntawm qhov kub siab, zoo weldability, thiab superior tiv thaiv oxidation (scaling) piv rau qis dua - qib carbon steels.
Chemical Composition (%)
Cov tshuaj muaj pes tsawg leeg yog tswj nruj me ntsis kom ntseeg tau tias kev ua haujlwm zoo ib yam. Hauv qab no yog ntau yam raws li ASTM A210 / ASME SA-210 tus qauv.
| Lub ntsiab | Kev sib xyaw (%) |
|---|---|
| Cov pa roj carbon (C) | 0.35 max |
| Manganese (Mn) | 0.29 - 1.06 |
| Phosphorus (P) | 0.035 max |
| Sulfur (S) | 0.035 max |
| Silicon (Si) | Ntau dua lossis sib npaug li 0.10 |
Nco tseg:Cov ntsiab lus siab Manganese (Mn) yog qhov muab SA-210C nws lub zog txhim kho.
Mechanical Properties
Mechanical zog yog guaranteed los ntawm kev xeem.
| Khoom | Tus nqi |
|---|---|
| Tensile zog | 70,000 psi (485 MPa) min |
| Yield zog | 40,000 psi (275 MPa) min |
| Elongation | 30% min (hauv 2 nti) |
Kub thiab siab ntsuas
SA-210C yog tsim los rausiab -kev pabcuam kub. Nws qhov siab tshaj plaws tso cai rau kev ntxhov siab txo qis thaum kub nce. Cov txiaj ntsig no tau luam tawm nyob rau hauvASME Boiler thiab Pressure Vessel Code, Tshooj II, Ntu D.
Yam Kev Thov Kev Kub Kub Ntau Yam:Mus txog ~ 1000℃F (538 degree). Rau qhov kub siab tshaj qhov no, alloy steels zoo li SA-213 T11, T22, lossis stainless hlau feem ntau yog siv.
Kev txwv tseem ceeb:Thaum muaj zog, nws yog raug raugraphitization(ib daim ntawv ntawm embrittlement) thaum raug kub siab tshaj 800℃F (427 degree) rau lub sij hawm ntev heev (ntau txhiab teev). Qhov no yog ib qho tseem ceeb rau kev txiav txim siab rau cov seem superheater.
Cov ntawv thov siv
SA-210C yog cov khoom siv ua haujlwm rau ntau yam tseem ceeb hauv:
Fais fab Generation Boilers:Phab ntsa, ru tsev, hauv pem teb, thiab cov ntxaij vab tshaus hauv dej-cov phab ntsa ntawm cov pob zeb siv hluav taws xob.
Superheaters:Lub hauv paus thiab theem nrab superheater seem qhov twg chav yog rhuab mus rau nws qhov kawg kub.
Muaj boilers:Siv nyob rau hauv ntau yam txheej txheem industries xav tau chav.
Thaum tshav kub kub Exchangers:Hauv cov kab ke uas siab -siab thiab corrosion tsis yog thawj qhov kev txhawj xeeb.
Qhov zoo ntawm SA-210C
Tus nqi -zoo:Kev lag luam ntau dua li qis- alloys lossis stainless hlau.
Siab zog:Muab lub zog zoo heev - rau - qhov hnyav piv ntawm tus nqi tsim nyog.
Zoo Weldability:Yuav tau yooj yim welded siv cov txheej txheem xws li SMAW (Stick), GTAW (TIG), thiab GMAW (MIG), txawm tias ua ntej - cua sov thiab tom qab -weld heat treatment tej zaum yuav xav tau rau cov seem tuab.
Formability zoo:Yuav khoov thiab fabricated nrog tus txheeb ze yooj yim.
Zoo thermal conductivity:Ua haujlwm zoo rau kev hloov cua sov.
Kev txwv thiab kev txiav txim siab
Corrosion Resistance:Tsuas muaj tsawg kawg nkaus tiv thaiv corrosion. Nws tsis haum rau acidic, caustic, lossis marine ib puag ncig yam tsis muaj kev tiv thaiv. Internal boiler dej chemistry yuav tsum tau ua tib zoo tswj kom tsis txhob muaj corrosion.
Tsawg-Tub kub Brittleness:Zoo li feem ntau cov pa roj carbon steels, nws muaj qhov zawv zawg - mus rau - qhov hloov pauv kub thiab tuaj yeem ua nkig hauv qhov chaw txias heev.
Graphitization:Raws li tau hais, ntev -lub sij hawm raug kub siab tshaj 800℃F tuaj yeem ua rau graphitization, uas ua rau cov hlau tawg.
Sib piv nrog Lwm Qib
| Qib | Qhov txawv tseem ceeb | Hom Siv Case |
|---|---|---|
| SA-210A1 | Cov ntsiab lus qis Mn, qis zog. | Txo qhov kub / siab ntawm lub boiler. |
| SA-210 C | Cov ntsiab lus Mn siab dua, muaj zog dua. | Siab dua qhov kub / qhov siab, superheaters. |
| SA-106 C | Zoo sib xws chemistry, tab sis raukav dejtshuab. Nws muaj qhov sib txawv ntawm kev tsim khoom thiab kev sim. | Kev pabcuam dav dav thiab siab -cov kav dej kub, tsis tshwj xeeb boiler/superheater raj. |
Cov ntsiab lus
SA-210 Cyog lub siab -zoo, seamless carbon steel raj tshwj xeeb tsim los rau kev thov siab - kub thiab siab - kev pabcuam siab hauv kev siv boiler thiab superheater. Nws qhov sib npaug ntawm lub zog, kev tsim khoom, thiab tus nqi ua rau nws yog ib qho khoom siv tseem ceeb hauv lub zog thiab kev lag luam. Thaum xaiv nws, engineers yuav tsum ua tib zoo xav txog qhov kev khiav hauj lwm kub kom tsis txhob ntev - lub sij hawm degradation mechanisms xws li graphitization.
Lus Cim Tseem Ceeb:Rau ib qho tiag tiag -lub ntiaj teb engineering lossis kev yuav khoom, nco ntsoov xa mus rau qhov tseeb version of theASME SA-210specification thiab sab laj covASME Boiler thiab Pressure Vessel Coderau qhov tso cai rau kev ntxhov siab thiab tsim cov cai.
