Cov Ntawv Thov
ASTM A501 Cov Hlau Leeg yog siv dav hauv:
- Cov qauv txheej txheem ua haujlwm(cov tuam tsev, txuas hniav, yees)
- Siv kev pab txhawb nqa(kab, kab teeb, trusses)
- Muaj Cov Cuab Yeej Siv(Scaffolding, Machinery Frames)
- Cov phiaj xwm kev ua haujlwm(Kev tiv thaiv loj, kos npe qauv)
Qhov Zoo
Nqi -}}}}: Txo cov nqi ntau lawm piv rau cov khaub thuas - tsim cov leeg (piv txwv li, astm A500).
Lub zog siab - rau - qhov hnyav} qhov hnyav. Piv: Haum rau hnyav - Log qauv qauv.
Weldability & formability: Yooj yim welded thiab siv ntaub rau hauv cov qauv nyuaj.
Yam ruaj khov: Tiv taus deformation nyob rau hauv kev ntxhov siab.
Kev sib piv nrog lwm cov qauv
ASTM A500: Cold {- tsim qauv kev tsim qauv tubing nrog lub zog nruj me me tab sis tus nqi siab dua.
ASTM A53: General {- hom phiaj yeeb (tsis tshwj xeeb rau kev siv cov qauv txheej txheem).
ASTM A1085: Txhim kho thaj chaw thiab cov yam ntxwv ruaj khov.
Tag
ASTM A501 cov hlau tub rog yog ib qho ntau yam, kev xaiv nyiaj txiag rau cov ntawv thov cov kev thov uas muaj zog thiab muaj kev vam meej yog qhov tseem ceeb. Lawv kub - tsim cov txheej txheem tsim kom muaj zog kom ua kom muaj zog, ua rau lawv zoo tshaj rau kev tsim kho thiab hnyav engineering.
