** 1. Dab tsi yog A333? **
ASTM A333 yog tus qauv tshwj xeeb rau kev sib khi thiab welded steel yeeb nkab npaj rau kev pab kub tsawg. Nws npog ntau ntau cov qib uas haum rau kev siv nyob rau hauv cov chaw nyob qhov twg tsawg-kub kev tawv yog qhov tseem ceeb.
** 2. Yog ASTM A333 qib 6 carbon hlau? **
Yog lawm, Astm A333 qib 6 yog cov tshuaj carbon hlau alloy. Nws yog tshwj xeeb tsim rau cov kev siv kub tsawg, muab cov khoom siv nruj ua kom sov ntawm qhov kub uas muaj tsawg li {} {{{4 4} degree).
** 3. Puas yog A333 tua cov roj carbon hlau? **
Yog lawm, Astm A333 cov kav dej ib txwm ua los ntawm ** tua cov hlau tua ** (tag nrho Dazidized hlau). Qhov no ua kom cov homogeneity thiab txhim kho kev cuam tshuam nyuaj ntawm tsawg kub, uas yog qhov tseem ceeb rau cov kev pabcuam ua haujlwm.
** 4. Dab tsi yog qhov sib txawv ntawm Astm A53 thiab A333? **
- ** ASTM A53 **: Siv rau cov ntawv thov dav dav (piv txwv li, cov kav dej, qauv) ntawm qhov chaw kub ntawm huab cua. Nws muaj nyob hauv welded lossis seamless cov ntaub ntawv thiab tsis tas yuav muaj kev sim tsawg-kev cuam tshuam kev cuam tshuam.
- ** ASTM A333 **: Tsim los ** Kev pabcuam tsawg dua ** (piv txwv li, cryogenic ib puag ncig). Nws yuav tsum muaj kev cuam tshuam charpy kev sim ua kom pom tseeb qhov kub thiab txias thiab feem ntau yog ib txwm ua) los txhim kho kev kub ntxhov.
** 5. Qhov twg yog qhov zoo dua, ASTM A106 B lossis ASTM A53 B? **
- ** ASTM A106 B **: Cov yeeb nkab Seamless Hlau rau ** Cov Kev Pabcuam Kub Kub ** (piv txwv li, roj av ntxiv). Nws muaj cov txheej txheem stricter thiab cov neeg kho tshuab ib zaug li A53.
- ** ASTM A53 B **: Ib qho kev siv hluav taws xob dav dav rau ** cov ntawv thov kub ambient kub **, muaj nyob rau hauv welded lossis seamless cov ntawv.
** Xaiv yog nyob ntawm daim ntawv thov **:
- Siv ** A106 b ** rau qhov siab-ntsuas kub \/ siab.
- Siv ** A53 b ** rau cov nqi-ua tau zoo, qis-rau-nruab nrab kub \/ siab siv.
