ASTM A210 / ASME SA210 raj yog seamless nruab nrab carbon steel boiler thiab superheater raj. Nws yog dav siv nyob rau hauv kev tsim ntawm boilers, siab hlab ntsha, thiab tshav kub exchangers vim nws zoo heev mechanical zog thiab siab tiv thaiv corrosion.
Cov lus qhia tshwj xeeb yog tsim los siv rau hauv qhov chaw kub kub uas qhov kub tuaj yeem ncav cuag 760 degree. Qhov kev qhia tshwj xeeb no tau teeb tsa tus qauv rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov kev xav tau ntawm cov raj no.
Cov tshuaj muaj pes tsawg leeg ntawm A210 raj muaj xws li carbon, manganese, phosphorus, sulfur, thiab silicon. Cov ntsiab lus carbon yog li ntawm 0.27% mus rau 0.35%, thaum cov ntsiab lus manganese nyob ntawm 0.93% mus rau 1.06%. Cov ntsiab lus phosphorus thiab sulfur yog txwv rau 0.035%, thaum cov ntsiab lus silicon tsis ntau tshaj 0.10%.
Mechanical zog ntawm lub raj no kuj tseem ceeb heev uas yuav tau xav txog. Qhov tsawg kawg nkaus tensile lub zog ntawm qib no yog 415 Mpa, thaum lub zog tawm los yam tsawg kawg nkaus yog 255 Mpa. Lub elongation ntawm so yog qhov tsawg kawg yog 30%.
Txhawm rau kom ntseeg tau tias A210 tube ua tau raws li qhov xav tau tshwj xeeb, nws dhau los ua ntau yam kev sim thaum lub sijhawm tsim khoom. Cov kev ntsuam xyuas no suav nrog kev sim flattening, kuaj flaring, kuaj hardness, kuaj hydrostatic, thiab kuaj hluav taws xob tsis muaj kev puas tsuaj.
Hauv kev xaus, ASTM A210 / ASME SA210 raj yog qhov zoo tshaj plaws seamless nruab nrab carbon steel boiler thiab superheater raj uas yog dav siv nyob rau hauv kev tsim boilers, siab hlab ntsha, thiab tshav kub exchangers. Nws cov cuab yeej zoo heev thiab kev ua haujlwm siab rau corrosion ua rau nws yog qhov kev xaiv nrov rau cov chaw kub kub.
