Product Description
Cold drawn precision steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to its advantages such as no oxide layer on the inner and outer walls, no leakage under high pressure, high precision, high smoothness, no deformation during cold bending, no expansion or cracking during flattening, precision steel pipes are mainly used in the production of pneumatic or hydraulic components such as cylinders or oil cylinders.
Product Features
1. Smaller outer diameter.
2. High precision for small-scale production
3. Cold drawn finished products have high precision and good surface quality.
4. The cross-sectional area of steel pipes is more complex.
5. Steel pipes have superior performance and denser metal
