Product introduction: Precision steel pipe high size, high precision, pipe inside and outside surface finish, after heat treatment of steel pipe inside and outside the surface are no oxide film, steel pipe flaring, flattening without cracks, cold bending without deformation, and can withstand high pressure, can make a variety of complex deformation and mechanical deep processing. The main production of steel pipe brands: 10#, 20#, 35#, 45#, 40cr, 42crmo, 16mn, etc Production specification: Outer diameter of steel pipe 12-159 Steel pipe wall thickness of 2-30 Basic use: Precision steel pipe is widely used in automobiles, motorcycles, electric vehicles, petrochemical, electric power, ships, aerospace, bearings, pneumatic components, medium and low pressure boiler seamless steel pipe and other fields, can also be applied to steel bar sleeve, bearings, hydraulic, mechanical processing and other fields! Production process: The production process of precision steel pipe is the same as that of ordinary seamless pipe, that is, there is a final pickling and cold rolling procedure. Precision steel pipe process flow Tube billet heating - inspection - skin - - - perforation, pickling passivation, grinding - oil lubrication dry - cold rolled - to - cut head - inspection, identification, finished product packaging
