Cold working method for cold drawn seamless steel pipe

Cold working method for cold drawn seamless steel pipe The cold working method of   seamless steel pipe ,  includes cold rolling and cold drawing method to produce a complete set of equipment for the pipe. It is a unit for deep processing of hot rolled pipe or welded pipe. The production characteristics of cold-rolled precision steel pipe processing pipe unit is that the pipe material is usually subjected to multiple cold deformations and work hardening from the input to the finished product. Therefore, the whole production process consists of multiple preparation processes and deformation processes, and has the characteristics of reciprocating cycle. This will involve  many processes, long production cycle, large metal consumption, low production efficiency, high precision, bright and smooth inner and outer surfaces, no peeling, no cracks, no pits. Different processing methods and corresponding auxiliary processes are selected according to the processing properties of the metal, the p
