hot-rolled seamless steel pipe ASTM A 53

Hot rolled 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, then sent to a heating furnace for heating and perforated on the punching machine. At the same time, the perforation is continuously rotated and advanced. Under the action of the roll and the head, a cavity is gradually formed inside the tube blank, which is called a capillary tube. Then send it to the automatic pipe rolling machine to continue rolling. Finally, the whole machine is uniform in wall thickness, and the sizing machine is sizing to meet the specification. Production of hot-rolled seamless steel tubes by continuous rolling mills is a more advanced method.
