Precision pipe is a high-precision, high brightness seamless steel pipe produced by cold drawing or cold rolling. Its inner and outer diameters can be accurate to within 0.2mm, while ensuring bending and torsional strength, it is light in weight, so it is widely used in the manufacture of precision mechanical parts and engineering structures.
The precision steel pipe has high dimensional accuracy and high surface finish, and there is no oxide film on the inner and outer surfaces of the steel pipe after heat treatment. deal with.
