1. The hydraulic cylinder pipe has a smaller outer diameter than the seamless tube, which can improve the surface roughness.
2. The requirements for accuracy are not high, and generally small-scale plants can be mass-produced.
3. After cold drawing, the accuracy will be greatly improved.
4.Improve the surface hardness of the steel pipe, can eliminate the deformation of the force, and increase the hardness by 4
5. Superior performance, low price and high density
