ASTM A213 Txuj Scope
1.1 Qhov kev qhia tshwj xeeb no suav nrog seamless ferritic thiab austenitic steel boiler, superheater, thiab cov cua kub hloov pauv, qib T91, TP304, thiab lwm yam. Cov hlau no tau teev tseg hauv Cov Lus 1 thiab 2.
1.2 Cov qib uas muaj tsab ntawv, H, nyob rau hauv lawv lub npe, muaj cov kev xav tau sib txawv ntawm cov qib zoo sib xws uas tsis muaj cov ntawv, H. Cov kev cai sib txawv no muab lub zog nkag siab ntau dua li ib txwm ua tiav hauv qib zoo sib xws yam tsis muaj qhov sib txawv no.
1.3 Qhov ntau thiab tsawg thiab thicknesses feem ntau muab rau cov specification no yog 1/8 in. [3.2 mm] nyob rau hauv txoj kab uas hla mus rau 5 in. [127 mm] nyob rau hauv sab nraud txoj kab uas hla thiab 0.015 rau 0.500 in. [0.4 mus rau 12.7 mm], inclusive, nyob rau hauv yam tsawg kawg nkaus phab ntsa thickness los yog, yog teev nyob rau hauv kev txiav txim, nruab nrab phab ntsa thickness.Tubing muaj lwm txoj kab uas hla tuaj yeem muab tau, yog tias cov raj no ua tau raws li tag nrho lwm cov kev cai ntawm qhov kev qhia no.
1.4 Cov txiaj ntsig tau teev tseg hauv SI units lossis nti-phaus units yuav tsum raug suav tias yog tus qauv.Nyob rau hauv cov ntawv nyeem, SI units tau qhia nyob rau hauv brackets.Cov txiaj ntsig tau teev tseg hauv txhua qhov system yuav tsis muaj qhov sib npaug;Yog li ntawd, txhua qhov system yuav tsum tau siv nws tus kheej ntawm lwm tus.Kev sib xyaw cov txiaj ntsig los ntawm ob lub tshuab yuav ua rau tsis ua raws li tus qauv.Cov inch-phaus units yuav tsum siv tshwj tsis yog lub npe "M" ntawm qhov kev qhia tshwj xeeb no tau teev tseg hauv qhov kev txiav txim.
TABLE 1 Chemical Composition Limits, %A, rau Low Alloy SteelA Qhov siab tshaj plaws, tshwj tsis yog muaj ntau lossis tsawg kawg yog qhia.Qhov twg ellipses (…) tshwm sim hauv cov lus no, tsis muaj qhov yuav tsum tau ua, thiab kev tshuaj xyuas rau lub caij tsis tas yuav txiav txim siab lossis tshaj tawm.
