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.
