ASTM A179 seamless steel pipe is generally manufactured on automatic pipe rolling lines. The solid tube billet is inspected to avoid surface defects, cut into the required length, centering on the perforated end face of the tube billet, and then sent to t
ASTM A209 T1 seamless steel tube magnetic particle inspection or penetration inspection, can effectively find surface cracks, folds, double skin, hair lines, pinholes and other surface defects. For ferromagnetic materials, magnetic particle detection meth
See for steel composition of ASTM A333 Gr.10 steel tube, whether it is uniform enough. Because of the inferior ASTM A333 Gr.10 steel tube, there are more impurities in the pipe, and the density of steel is too small. As soon as we look at the cross sectio
ASTM A333 Gr.10 seamless steel tube is boiled in boiling water for 30-60 minutes before quenching, which can eliminate 15% to 25% of the quenching internal stress and stabilize the residual austenite, and then undergo conventional cooling treatment at -60
