Precision steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipes, no leakage under high pressure, high precision, high smoothness, no deformation during cold bending, flaring, flattening, and no cracks, they are mainly used to produce products for pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes or welded joints.
