Dab tsi yog qhov txawv ntawm A335 thiab SA335 yeeb nkab

1. Txheem system thiab cov qauv ntawm daim ntawv thov
ASTM A335: Tus qauv tsim los ntawm Asmeskas haiv neeg rau kev sim thiab cov ntaub ntawv siv tshuab hluav taws xob (piv txwv li cov petrochemical, cov pettrechemical, petentional lub boilers, thiab lwm yam).
ASME Sa335: Txais yuav thiab hloov kho los ntawm American Society of Americical Engineers (ASME), tab sis nrog lwm cov kev siv nyiaj siab, thiab lwm cov ntawv thov kev nyab xeeb ntawm kev nyab xeeb tshwj xeeb (xws li). Cov ntsiab lus thev naus laus zis yog tib yam li astm A335, tab sis nrog cov khoom siv tshwj xeeb, thiab lwm yam khoom siv tseem ceeb uas yuav tsum tau ua haujlwm ASME.
2. Qhov sib txawv ntawm qib thiab kev xav tau
Kev Sib Tham ntawm Qib:
ASTM A335 and ASME SA335 grades (such as P11, P22, P91, etc.) and chemical composition is the same, for example, P11 Cr content of 1.00 ~ 1.5{{10}}%, Mo content of 0.44 ~ 0.65%.
Qhov sib txawv: ASME SA335 IMROSES Ntau txoj kev nruj me ntsis ntawm kev tsim khoom (piv txwv li ntawm Weld Hardness ntau (piv txwv li kev nyab xeeb ntev hauv kev ruaj khov ntev los yog cov xwm txheej siab.
3. Kev thov cov xwm txheej thiab cov ntawv pov thawj yuav tsum muaj
ASTM A335: Feem ntau yog siv nyob rau hauv cov pipelines muaj kev lag luam (piv txwv li cov roj hauv lub boilers), tsis tas yuav ua raws li cov qauv ua haujlwm hauv Astm qauv.
ASME Sa335: ASME BPV Code (Boiler thiab Cov Ntawv Cog Lus Siab Tshaj Plaws, thiab lwm yam kev pheej hmoo ntawm lub zog, thiab lwm yam xwm txheej siab ntev
4. Cim thiab Ua Raws
Cov Ntawv Cim Khoom: ASME SA335 Tubing yog cim nrog ib 'desix (piv txwv li, sa335 p11) kom sib txawv nws los ntawm nws cov astm A335 counterpart.
Cov Ntaub Ntawv Ua Raws Cai: ASME SA335 Yeeb Nkab yuav tsum tau nrog Cov Ntawv Qhia Kev Ntsuam Xyuas (piv txwv li cov ntaub ntawv ua kom sov, cuam tshuam rau cov ntaub ntawv kub, feem ntau tsuas yog yuav tsum tau raws li cov qauv kev lag luam dav dav.
