Precision steel pipe is a high-precision steel tube material produced through 

cold drawing or hot rolling. Due to its advantages such as lack of oxide layers

 on the inner and outer walls, ability to withstand high pressure without leakage,

 high precision, high finish, no deformation during cold bending, and no cracks 

during expansion or flattening, precision steel pipe is primarily used in the production

 of pneumatic and hydraulic components, such as cylinders. It can be either seamless or welded.

Precision steel pipes feature high dimensional accuracy and smooth internal and external surfaces. 

After heat treatment, the pipes are free of oxide film on both the inner and outer surfaces.

 They exhibit crack-free flaring and flattening, retain deformation during cold bending, 

and withstand high pressure, various complex deformations, and deep mechanical processing.

Main steel pipe grades produced: 10#, 20#, 35#, 45#, 40Cr, 42CrMo, 16MN, etc.

Other grades of precision seamless steel pipe can be supplied upon request.

Main production bases for precision seamless steel pipes: Shandong, Jiangsu, Chengdu, Tianjin, Hebei, etc.
