Introduction:
Cold drawn precision seamless steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening and no cracks, they are mainly used to produce pneumatic or hydraulic components, such as cylinders or The cylinder can be a seamless tube.
National standards for cold drawn precision seamless steel tubes in stock; GB/T699-2008, cold drawn precision seamless steel tubes in stock, national standards for cold drawn precision seamless steel tubes in stock; GB/T3639-2008, and GB/T T8162-2008 precision steel pipe for structure. The European standard of cold drawn precision seamless steel pipes is: DIN2391 basic purpose cold drawn precision seamless steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, bearings, pneumatic components, medium and low pressure boiler seamless steel pipes, etc. It can also be applied to steel sleeves, bearings, hydraulics, machining and other fields!
