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, 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. After the uniform machine is even wall thickness, sizing through the sizing machine to meet the specifications. The production of hot-rolled 45# seamless pipes and tubes by continuous rolling mills is a more advanced method.
