Precision Pipe Features

The characteristics of
1. Smaller outside diameter.
2. High precision for small batch production.
3. High precision and good surface quality of cold-drawn products.
4. The cross area of steel pipe is more complicated.
5. Steel tubes have superior performance and dense metal.

Precision tube is a kind of seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling process.Its inside and outside diameter size can be accurate to within 0.2mm, while ensuring bending and torsion strength, light weight, so it is widely used in manufacturing precision machinery parts and engineering structures. It is also commonly used to produce all kinds of conventional weapons, barrels, shells, bearings, etc.
