Hot rolled seamless pipes are generally produced on automatic pipe rolling units. The solid tube is inspected and surface defects are removed, cut into the required length, centered on the end face of the tube blank perforation, and then sent to the heating furnace for heating, and perforated on the perforation machine. During perforation, the tube continuously rotates and advances, and under the action of the rolling mill and the top, a cavity gradually forms inside the damaged tube, which is called a capillary tube. Then it is sent to the automatic pipe rolling machine for further rolling, and the wall thickness is uniformly adjusted throughout the machine. The sizing machine is used for sizing to meet the standard requirements. The use of a continuous rolling mill to produce hot-rolled ASTM A106 seamless pipes is an advanced method. ASTM A106 seamless pipes have a wide range of applications, mainly used as pipelines or structural components for transporting fluids. These two processes differ in terms of precision, surface quality, minimum size, mechanical properties, and microstructure.

ASTM A106Gr.B seamless steel pipe is a widely used low-carbon steel, which is widely used in the petroleum, chemical and boiler industries. The material has good mechanical properties. A106-B steel pipe is equivalent to my country's 20 steel seamless steel pipe, and implements the ASTM A106/A106M high-temperature carbon steel seamless steel pipe standard, grade B. It can be seen from the ASME B31.3 chemical plant and oil refinery pipeline standard: A106 material use temperature range: -28.9~565℃.
