Honing tube|polishing tube professional processing and sales, support customized service, to meet all your needs!
Honed steel pipe is a high-precision steel pipe material after cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation during cold bending, flaring, flattening and no cracks, etc., they are mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes. The chemical composition of honing steel pipe includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P and chromium Cr.
