ASTM A672 Qib C60 Hluav Taws Xob -Fusion-Welded Steel Pipe piav qhia
ASTM A672 C60 EFW Yeeb Nkab yog qhov nruab nrab -kub siab- bearing electrofusion welded carbon steel yeeb nkab ua raws li tus qauv ASTM A672. Nws cov yam ntxwv tseem ceeb yog:
"C60": Cov ntaub ntawv qib, carbon manganese steel (C Tsawg dua lossis sib npaug li 0.22%, Mn: 1.00-1.60%) nrog qhov tsawg kawg nkaus lub zog ntawm 60 ksi (415 MPa).
"EFW": Cov txheej txheem tsim khoom yog electrofusion welding, ua tiav ib daim ntawv cog lus seamless los ntawm melting cov hlau strip npoo nrog cov hluav taws xob arc.
Kev kho cua sov: yuam normalizing (890-930℃cua txias) los txhim kho qhov kub thiab txias.
Kev soj ntsuam qib: Yuav tsum ua kom haum rau Chav Kawm 12/22/32 (default Class 22, ib feem tsis yog-kev kuaj kev puas tsuaj).
