SIB 36steel yog ib qho dav - lub hom phiaj carbon structural steel specification txhais los ntawm ASTM International, dav siv rau riveted, bolted, los yog welded kev tsim kho ntawm choj, vaj tse, thiab cov hom phiaj dav dav.
"SA" ua ntej tshwj xeeb qhia tias cov khoom ua raws li ASME Boiler thiab Pressure Vessel Code (BPVC) version ntawm ASTM specification, txhais tau tias nws tau txais los siv rau hauv lub nkoj siab thiab boiler kev tsim kho. Rau tag nrho cov khoom siv kho tshuab thiab tshuaj lom neeg, SA36 zoo ib yam rau cov feem ntau siv ASTM A36 steel.
Cov yam ntxwv tseem ceeb ntawm SA36 / A36:
Hom: Tsawg- carbon, me ntsis steel.
Tawm Zog: Tsawg kawg 36,000 psi (250 MPa).
Tensile zog: 58, 000 - 80,000 psi (400 - 550 MPa).
Qhov Tseem Ceeb: Nws yog qib "lub zog-tsuas yog" qib. Tsis zoo li ntau qib European (piv txwv li, S355J2), nws tsis muaj qhov yuav tsum tau muaj kev cuam tshuam toughness (Charpy) cov cai hauv nws qhov kev qhia tshwj xeeb.
Weldability: Zoo heev, vim nws cov ntsiab lus carbon tsawg.
Common Forms: Phaj, tuav, cov qauv duab (beams, ces kaum, raws).
Cov ntawv thov raug:
Lub tsev thav duab thiab cov qauv kev lag luam.
Base phaj, tshuab qhov chaw, thiab brackets.
Tsis yog - cov khoom tseem ceeb ntawm cov choj.
General fabrication qhov twg siab zog los yog tsawg -kub toughness tsis yog ib qho kev txhawj xeeb tseem ceeb.
Cheebtsam hauv ASME-cov hlab ntsha siab (thaum teev raws li SA36).
Tsis muaj qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, lossis metallurgy ntawm SA36 thiab A36 steel. Qhov sib txawv yog kev tswj hwm nkaus xwb thiab muaj feem xyuam rau txoj cai tswj hwm raws li cov khoom yuav thiab ntawv pov thawj.
Ntawm no yog qhov yooj yim tawg:
| Feature | ASTM A36 | ASME SA36 |
|---|---|---|
| Lub Koom Txoos Kav Tos Liv | ASTM International (yav tas los American Society for Testing and Materials). | ASME (American Society of Mechanical Engineers). |
| Lub Hom Phiaj | Cov khoom siv tshwj xeeb rau kev siv cov qauv siv hauv vaj tse, txuas hniav, thiab kev tsim kho dav dav. | Cov khoom siv zoo ib yam tau txais thiab luam tawm los ntawm ASME rau siv hauv boilers, cov hlab ntsha siab, thiab cov khoom siv nuclear. |
| Qhov Tseem Ceeb | Nws yog ib tug standalone khoom txheem. | Nws yog "Code Material." Qhov "S" ua ntej txhais tau tias nws ua raws li cov cai ntawm ASME Boiler thiab Pressure Vessel Code (BPVC), Tshooj II, Ntu A. |
| Ntawv pov thawj & Traceability | Muaj ntawv pov thawj kom tau raws li ASTM A36 cov cai. Cov ntaub ntawv ua raws li ASTM kev coj ua. | Yuav tsum tau tsim, kuaj, thiab ntawv pov thawj raws li kev ua tau zoo raws li ASME cov cai. Qhov no feem ntau suav nrog cov ntaub ntawv nruj dua thiab kev taug qab, suav nrog kev muaj peev xwm ua pov thawj los ntawm Tus Neeg Saib Xyuas Tso Cai rau daim ntawv thov nuclear. |
| Kev Siv Tau | Koj yuav A36 rau lub tsev thav duab, lub tsev khaws khoom, lossis lub khw tsis yog -code fabrication shop. | Koj qhia SA36 thaum cov khoom sib xyaw ua ke rau hauv ASME-stamped siab hlab lossis boiler. Tus neeg tsim khoom nrog ASME "U" thwj yuav tsum siv SA36 (tsis yog A36 nkaus xwb) rau cov lej- khi qhov chaw. |
Lub tswv yim tseem ceeb: "Ib yam tab sis txawv"
Xav txog qhov no:
ASTM A36 txhais tau tiasdab tsicov hlau yog (nws cov chemistry thiab cov khoom).
ASME SA36 hais tias,"Qhov no yog tib yam A36 steel, tab sis nws tau raug tsim, sim, thiab sau tseg raws li cov kev ruaj ntseg ntxiv thiab traceability cov cai ntawm ASME Code."
Lawv puas tuaj yeem hloov tau?
SA36 ib txwm siv tau rau qhov chaw ntawm A36 (nws yog tib yam khoom, ntxiv rau daim ntawv pov thawj ntxiv). Nws feem ntau hu ua "code quality" version.
A36 tuaj yeem tsis tuaj yeem siv los ntawm SA36 rau ASME Code kev tsim kho tshwj tsis yog nws tau rov- tshuaj xyuas thiab rov- tau lees paub los ntawm tus neeg xa khoom kom ua tau raws li SA/ASME cov cai. Rau code- stamped ua hauj lwm, cov khoom yuav tsum tau txiav txim raws li SA36.
Xaus
Rau txhua qhov kev suav engineering, cov txheej txheem vuam, thiab cov khoom siv lub cev, SA36 thiab A36 yog tib yam hlau. Qhov sib txawv tsuas yog kev tswj hwm thiab kev tswj hwm kev ua haujlwm tau zoo los ntawm ASME Boiler thiab Pressure Vessel Code rau kev nyab xeeb- cov ntawv thov tseem ceeb. Yog tias koj qhov project tsis tswj hwm los ntawm ASME code, koj feem ntau yuav yuav A36. Yog tias koj tab tom tsim lub nkoj siab, koj yuav tsum qhia SA36.
