GB/T1591 Q345A LSAW Pipe

Q345A welded yeeb nkab yog ib hom hlau nrog lub zog zoo tab sis kev ua haujlwm tsis zoo. Nws yog cov hlau tsis tshua muaj hlau thiab siv dav hauv cov txuas hniav, tsheb, nkoj, cov tsev, cov nkoj siab, thiab lwm yam.
Piv nrog Q345B, C, D, thiab E steel, Q345A ncaj seam steel yeeb nkab muaj qhov ntsuas kub qis qis, kev ua haujlwm tsis zoo, thiab muaj cov khoom tsis zoo P thiab S ntau dua Q345B, C, D, thiab E.
Q sawv cev rau cov txiaj ntsig ntawm cov khoom no, thiab cov hauv qab no 345 yog hais txog tus nqi tawm ntawm cov khoom no, uas yog nyob ib ncig ntawm 345MPa. Thiab raws li cov thickness ntawm cov khoom nce, nws cov nqi tawm los txo.
Q345A Dab tsi yog cov khoom siv ntawm welded steel yeeb nkab?
Phab ntsa thickness mm Tsawg dua los yog sib npaug rau 16, elongation δ5 Ntau dua los yog sib npaug rau (%) 21, yield zog δs (MPa Ntau dua los yog sib npaug rau) 345, ntsuas kub tsis tas yuav tsum tau, tensile zog σb (MPa Ntau dua lossis sib npaug rau ) (470-630).
