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, that`s how Sinton seamless stainless steel pipe was manufactured.
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 pipe size, the quality requirements, and the investment and benefits. The basic processes cold drawn precision steel pipe are as follows:
