Dab tsi yog ASTM A276 / A276M-06 ib?
ASTM A276 / A276M -06 ib npog kub, tsuas yog rau cov khoom siv uas tsis muaj txiaj ntsig, tsis meej rau cov neeg siv hluav taws xob, tsis yog rau cov neeg siv hluav taws xob, tsis yog rau cov khoom siv sib txawv
ASTM A276: Siv nti nti cov units .
ASTM A276M: Metric Version Siv Si Units .
06: yog hais txog 2006 kev kho dua tshiab nrog cov hloov tshiab me me.
Tus qauv no tsis hais ntxiv cov tuav, rebar, lossis xaim, uas tau them rau hauv cov .

ASTM A276 / A276M Qhov Ntev & Kev Ua Phem
Tus qauv siv rau cov kab hauv cov qhov ntev hauv qab no:
Puag ncig cov ceg: Feem ntau los ntawm 1/8 "rau 12" lub taub
Tiaj ceg: Txog li 12 "qhov dav thiab 3" tuab
Kev thev: Raws li ib astm A484 / A484m, suav nrog txoj kev ncaj, ntev, thiab seem txwv.
ASTM A276 VS ASTM A479: Dab tsi yog qhov sib txawv?
| Lub hom phiaj | ASTM A276 | ASTM A479 |
|---|---|---|
| Daim ntawv thov | Cov txheej txheem thiab machining tuav | Siab Hlab Thiab Siab Piping |
| Kev Kho Cua Sov | Yeem tshwj tsis yog teev | Yuav tsum tau rau feem ntau cov qhab nia |
| Khoom daim ntawv | Tuav (kub / txias tiav) | Tuav thiab cov duab rau ASME code thov |
Ntsiab lus: Yog tias koj daim ntawv thov cuam tshuam nrog ASME siab txog kev ua haujlwm, xaiv} rau cov qauv dav dav lossis machining siv, A276 muaj ntau dua .
ASTM A276 S31803 Cov khoom sib npaug
