What is precision seamless steel pipe

Precision seamless pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to the absence of oxidation layer on the inner and outer walls of precision steel pipes, high pressure resistance without leakage, high precision, high smoothness, cold bending without deformation, expansion, flattening without cracks, etc., it is mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders. It can be seamless pipe or welded pipe. The chemical composition of precision steel pipes includes carbon C, silicon Si, etc Manganese Mn, sulfur S, phosphorus P, chromium Cr, seamless steel pipes, compared with solid steel such as round steel, have lower weight when their bending and torsional strength are the same. They are an economical cross-section steel and are widely used in the manufacturing of structural and mechanical parts
