  Seamless steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Because of the precision steel pipe inside and outside wall without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks a bit, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder,API Hot-Rolled seamless steel pipe can be a seamless steel pipe, welded pipe. The chemical components of precision steel pipes are carbon C, Si Si, Mn, sulfur S, P and Cr.

  The difference between precision steel pipe and seamless steel pipe.

  1. The main feature of seamless steel pipe is no welding seam, which can withstand greater pressure. The product can be a very rough cast or cold dial.

  2. Precision steel pipe is a product that has appeared in recent years. It is mainly the inner and outer wall dimensions with strict tolerance and roughness.
