Hot rolled 45# seamless pipes are generally produced on automatic rolling mills. The solid tube blank is inspected and the surface defects are removed, cut into the required length, centered on the end face of the perforated end of the tube blank.

ASTM A519 4130 tubing has excellent strength-to-weight ratio and are considerably stronger and harder than standard 1026 tubing. 4130 tubing has a relatively low carbon content so it welds and machines almost as easily as 1018 carbon steel tubing.
