Manufacturing method of Steel Honed Tube

- Dec 17, 2020-

The invention belongs to the technical field of steel pipe preparation, and specifically relates to a method for manufacturing a honing pipe.

As a cold working method for steel pipes for mechanical structures, such as carbon steel, alloy steel, or stainless steel, a drawing method by a drawing machine and a rolling method by a pilger mill are known. Among them, the drawing process performed by a drawing machine can produce cold-worked steel pipes more efficiently than the rolling process performed by a Pilger Zipper. Such seamless steel pipes are used for hydraulic and pneumatic cylinders. At present, the yield strength and dimensional deviation of the steel grades specified in the current domestic standards cannot meet the actual requirements for the use of hydraulic and pneumatic cylinders, making my country’s seamless steel pipes for hydraulic and pneumatic cylinders only dependent on imports, restricting The development of cold drawn steel pipes in China.

The purpose is to overcome the deficiencies in the prior art and provide a method for manufacturing honing pipes. The honing pipes obtained by this method have high yield strength, precise dimensions, smooth surface, good oil storage performance, and smooth operation. In the case of a standstill, the service life is extended, and it is suitable for various labor-saving automated mechanical projects such as hydraulic cylinders, pneumatic cylinders, forklifts, cranes, stackers, construction machinery, and punching machines.
