Introduction to stainless steel tube:
Stainless steel pipe is a hollow long cylindrical steel, his scope of application as a fluid pipeline, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipeline and mechanical structural components. Stainless steel pipes are made of acid and heat resistant billets, heated, perforated, sized, hot rolled and cut.
According to different production methods, it can be divided into hot rolled tube, cold rolled tube, cold drawn tube, extrusion tube and so on.
Hot rolled stainless steel seamless tubes are generally produced on automatic tube rolling sets. The solid tube blank is checked and cleared of surface defects, cut into the required length, centering on the perforated end face of the tube blank, and then sent to the heating furnace for heating, and perforated on the punch machine. In the perforation at the same time continuous rotation and forward, under the action of the roll and the top, the tube blank gradually formed a cavity, called the wool tube. Then it is sent to the automatic pipe mill to continue rolling. Finally, the wall thickness of the whole machine is adjusted, and the sizing machine is adjusted to meet the specification requirements. It is an advanced method to produce hot rolled seamless steel tube with continuous rolling tube set.
