S20C S45CHot Sales Precision cold drawn carbon seamless steel pipe
Precision 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 and no leakage, high precision, high finish, 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 or a welded tube.
The national standard of precision steel pipe; GB/T699-2008, the national standard of precision steel pipe; GB/T3639-2008, in addition, there may also be the application of GB/T8162-2008 precision steel pipe for structure.
European standard for precision steel pipe: DIN2391
Precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, seamless steel pipes for medium and low pressure boilers, etc., and can also be applied to steel sleeves, bearings, hydraulics, machining, etc. field!
