Precision Steel Pipe Features

a. You can get a smaller diameter with precision steel pipe
b. High precision pipe accept small quantity for MOQ.
c. The pipes with cold drawn processes has high precision and good surface finish.
d. The transverse area of the steel pipe is more complicated.
e. Performance is superior, with higher density.

Application of Precision Steel Tubing

The internal and external diameter could control within +/- 0.01 mm. In the guarantee of anti-bending strength and torque strength same, the weight of precision pipe is lighter. It can be widely used in manufacturing precision machinery parts and engineering structure, and also commonly used to produce various kinds of conventional weapons, barrel, shells, bearing and so on.
