Cold rolled precision steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Because there is no oxide layer on the surface and inner wall of cold-rolled precision steel pipe, no leakage under high pressure, high precision, high brightness, cold bending fixed shape, flaring, flattening and no crack, it is important that the products used to manufacture pneumatic or hydraulic components, such as air cylinder or oil cylinder, can be seamless pipes and can also be recycled by welding. The chemical factors of cold rolled tight steel pipe include carbon C, silicon Si, manganese Mn, sulfur s, phosphorus P and chromium CR.
Difference between cold rolled precision steel pipe and cold drawn seamless pipe
1. The important feature of cold drawn seamless pipe is that there is no welding seam, which can withstand greater pressure. The product can be very rough as cast or cold drawn parts.
2. Cold rolled precision steel pipe is a product discovered in recent years. The important thing is that the size of inner hole and outer wall has harsh small officials and roughness.
