Precision steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no cracks, it is mainly used to produce products of pneumatic or hydraulic components, such as air cylinder or oil cylinder, which can be seamless pipe or welded pipe.
It is mainly used as a pipe or structural part for conveying fluid. It is used as the raw material of high-pressure container and bottle, and as the pillar material of transmission pipeline, bridge and steel structure in high-temperature environment.
