Product Description
We manufacture and supply precision tubes, precision steel tubes, precision seamless tubes, precision seamless steel tubes and other precision tube products.
Precision steel pipe is a high-precision, high-brightness produced by cold drawing or cold rolling. Its inner and outer diameters can be accurate to within 0.2mm. While ensuring bending and torsional strength, it is light in weight, so it is widely used in the manufacture of precision mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, bearings, etc.
Commonly used materials are ST52, Q345B, CK20, CK45, SAE1026 10#、20#、35#、45#、20cr、40Cr、20CrMo﹑16mn﹑27simn﹑304﹑201﹑310s, high-quality carbon structural steel.
Characteristics of precision steel pipes
1. Smaller outer diameter.
2. High precision can be used for 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 complex.
5. The performance of the steel pipe is superior, and the metal is relatively dense.
