Product Description
The honed steel pipe is a high-precision steel pipe material that has been processed by cold drawing or hot rolling. Due to the characteristics of no oxide layer on the inner and outer walls of precision steel tubes, no leakage under high pressure, high precision, high smoothness, no deformation in cold bending, flaring, flattening and no cracks, etc., quilting milled pipes are mainly used to produce pneumatic or hydraulic components. Such as cylinder or cylinder seamless pipe.
Features of honed steel pipe
1. Smaller outer diameter.
2. High precision can do small batch production
3. The cold drawn finished product has high precision and good surface quality.
4. The cross-sectional area of the steel pipe is more complicated.
5. The performance of the steel pipe is superior, and the metal is relatively dense.
