Seamless Precision Tube Description
Precision seamless tube is a kind of high precision steel tube material after cold drawing or hot rolling. Because the inner and outer walls of precision steel tube have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and so on, it is mainly used to produce pneumatic or hydraulic components, such as cylinder or cylinder, can be seamless tube. There are also chemical components of welded pipe precision steel pipe, carbon C, silicon Si, manganese Mn, sulfur S, P, chromium Cr, seamless steel pipe and round steel and other solid steel, in bending and torsional strength at the same time, light weight, is a kind of economic section of steel, widely used in the manufacture of structural parts and mechanical parts.
