Processing and mechanical properties of the rolled tube Dec 24, 2018

Rolled tube can be effectively divided into hot rolled tubes, cold rolled tubes, cold drawn tubes, extruded tubes, etc., depending on the production method in the process of production. Hot rolled seamless pipes are generally produced on automatic pipe rolling units. 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. It is sent to the automatic pipe mill for further rolling. Finally,through Homogenizer to adjust the wall thickness and sizing machine to size to meet the specifications. The production of hot-rolled seamless steel tubes by continuous rolling mills is a more advanced method.
