ASTM Cov Qauv rau Cov Yeeb Nkab Hlau Carbon
Lub Koom Haum Asmeskas rau Kev Ntsuas thiab Cov Khoom Siv (ASTM) tau tsim ntau yam qauv rau cov kav hlau carbon, uas qhia meej txog qhov loj me, cov duab, cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab thiab lwm yam kev cai ntawm cov kav hlau. Cov hauv qab no yog ntau tus qauv ASTM rau cov kav hlau carbon:
1. Cov Kav Hlau Carbon Seamless
ASTM A53: Siv tau rau cov xim dub thiab cov xim dub uas tsis muaj qhov sib txuas thiab tsis sib txuascov kav hlau kub-dip galvanized, siv dav rau cov hom phiaj kev tsim kho, cov kav dej, thiab lwm yam. Tus qauv no muab faib ua peb qib: A, B, thiab C raws li phab ntsa tuab.
ASTM A106: Cov kav hlau carbon seamless uas tsim nyog rau kev pabcuam kub siab, muab faib ua Qib A, B, thiab C, feem ntau yog siv rau hauv cov roj, cov kav dej xa roj thiab cov lag luam tshuaj lom neeg.
ASTM A519: Siv tau rau cov hlau carbon seamless precision thiab cov kav dej rau kev ua haujlwm, nrog rau cov kev cai nruj heev.
2. Cov Kav Hlau Carbon Welded
ASTM A500: Siv tau rau cov khoom siv vuam txias thiab cov duab plaub fab tsis sib xws,duab plaub fabthiab lwm cov kav hlau uas zoo li tus, feem ntau siv rau hauv cov qauv tsev.
ASTM A501: Siv tau rau cov kav hlau kub dov thiab cov kav hlau tsis sib xws, cov kav hlau plaub fab, cov kav hlau plaub fab thiab lwm yam kav hlau zoo li tus.
ASTM A513: Siv tau rau hluav taws xobwelded puag ncig steel yeeb nkab, feem ntau siv rau kev siv tshuab thiab kev siv cov qauv.
3. Cov kav hlau carbon rau cov boilers thiab superheaters
ASTM A179: Siv tau rau cov kav dej boiler steel uas txias thiab tsis muaj carbon, tsim nyog rau cov ntawv thov pa dej siab.
ASTM A210: Siv tau rau cov kav dej boiler carbon steel seamless, muab faib ua plaub qib: A1, A1P, A2, thiab A2P, feem ntau yog siv rau cov boiler nruab nrab thiab qis siab.
ASTM A335: Siv tau rau cov kav dej kub siab ferritic alloy steel seamless, muab faib ua ntau qib, xws li P1, P5, thiab lwm yam, tsim nyog rau cov kav dej kub siab hauv kev lag luam petrochemical thiab fais fab.
4. Cov kav hlau carbon rau cov roj thiab cov qhov dej roj
ASTM A252: Siv tau rau kev sib txuas ntawm cov kab sib txuas hauv qab dejcov kav hlau vuamrau cov piles, feem ntau siv rau hauv kev tsim kho platform offshore.
ASTM A506: Siv tau rau cov kav hlau uas muaj zog thiab tsis tshua muaj hlau, tsim nyog rau kev tsim cov khoom siv roj thiab roj av.
ASTM A672: Siv tau rau cov kav hlau carbon manganese silicon uas muaj zog siab, tsim nyog rau cov ntawv thov uas xav tau lub zog siab dua.
API Spec 5LTxawm hais tias tsis yog tus qauv ASTM, nws yog tus qauv thoob ntiaj teb lees txais rau cov kav hlau rau cov kav roj thiab roj av, uas suav nrog ntau hom kav hlau carbon.
5. Cov kav hlau carbon rau cov hom phiaj tshwj xeeb
ASTM A312: Siv tau rau cov kav dej stainless hlau uas tsis muaj qhov sib txuas thiab cov kav dej vuam. Txawm hais tias nws yog rau cov hlau stainless hlau, nws kuj suav nrog qee cov lus qhia tshwj xeeb ntawm cov hlau carbon.
ASTM A795: Siv tau rau cov hlau carbon thiab cov hlau alloy billets, cov billets puag ncig thiab lawv cov khoom ua los ntawm kev casting thiab forging tas mus li, tsim nyog rau cov teb kev lag luam tshwj xeeb.
Yuav ua li cas xaiv tus qauv ASTM zoo
Kev xaiv tus qauv ASTM zoo nyob ntawm cov kev cai thov tshwj xeeb:
Siv ib puag ncig: Xav txog tej yam xws li qhov kub thiab txias ua haujlwm, qhov kub siab, thiab qhov muaj cov xov xwm corrosive.
Cov khoom siv kho tshuab: Txheeb xyuas qhov tsawg kawg nkaus ntawm lub zog tawm los, lub zog tensile thiab lwm yam cim qhia tseem ceeb.
Qhov tseeb ntawm qhov ntev: Rau qee qhov kev siv tshuab ua kom raug lossis kev sib dhos, yuav tsum tau tswj hwm qhov ntev sab nraud thiab phab ntsa kom nruj dua.
Kev kho qhov chaw: Txawm tias yuav tsum tau kub-dip galvanizing, pleev xim lossis lwm yam kev kho mob tiv thaiv xeb.
