We can produce outer diameter 4mm-273mm, high precision cold drawn steel tube, cold-rolled steel tube, precision steel pipe, stainless steel tube, stainless steel tube wall thickness 0.1mm-25mm, accuracy up to /+0.025 mm, roughness of 0.2.
It is mainly used in hydraulic system pipes, automobile manufacturing pipelines, military industry, construction machinery, railway locomotives, aerospace, ship, building, petrochemical, power plants, boiler equipment, etc.
There are 6 main characteristics of our product:
1. There is no oxide layer on the inner wall and outer wall.
2. No leakage under tremendous pressure.
3. High accuracy.
4. High finish.
5.Cold bending without deformation.
6.No combustion, shrinkage, flattening, no cracks.
