ASTM / ASME SA 276 thiab SA 479 yog ob qho kev qhia tshwj xeeb uas npog stainless hlau tuav. Txawm li cas los xij, muaj qee qhov sib txawv ntawm ob:
Scope:
ASTM / ASME SA 276: Qhov kev qhia tshwj xeeb no suav nrog cov hlau tsis muaj steel, suav nrog cov khoom kub ua tiav lossis txias tiav, rounds, squares, hexagons, thiab kub dov los yog extruded duab xws li cov ces kaum, tees, thiab raws.
ASTM / ASME SA 479: Qhov kev qhia tshwj xeeb no suav nrog stainless hlau tuav thiab cov duab siv rau hauv boilers thiab lwm cov hlab ntsha.
Chemical Composition thiab Mechanical Properties:
Ob qho kev qhia tshwj xeeb qhia txog cov kev cai tshwj xeeb rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab lwm yam khoom ntawm stainless hlau tuav. Txawm li cas los xij, qhov yuav tsum tau muaj tseeb yuav txawv nyob ntawm qib ntawm stainless hlau tau teev tseg.
Daim ntawv thov:
ASTM / ASME SA 276: Stainless hlau tuav tau teev tseg raws li SA 276 feem ntau yog siv rau ntau yam kev lag luam, suav nrog kev tsim kho, tsim khoom, thiab kev tsim vaj tsev dav dav.
ASTM / ASME SA 479: Stainless hlau tuav tau teev nyob rau hauv SA 479 tshwj xeeb yog tsim los siv rau hauv boilers thiab siab hlab ntsha, qhov siab corrosion kuj thiab mechanical zog yuav tsum tau.
Ntawv pov thawj:
Ob qho kev qhia tshwj xeeb xav tau cov khoom lag luam kom muab cov ntaub ntawv soj ntsuam cov ntaub ntawv pov thawj ua raws li cov kev cai tshwj xeeb. Cov ntawv ceeb toom no feem ntau suav nrog cov ntsiab lus ntawm cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab lwm yam kev sim ntxiv ua tiav ntawm cov khoom siv.
Hauv cov ntsiab lus, thaum ob qho tib si ASTM / ASME SA 276 thiab SA 479 npog stainless hlau tuav, SA 276 yog dav dav thiab npog ntau yam kev siv, thaum SA 479 tshwj xeeb rau cov tuav thiab cov duab siv rau hauv boilers thiab siab hlab ntsha.
