Is the corrosion resistance of precision cold drawn steel pipes strong

2025-03-26

The corrosion resistance of precision cold drawn steel pipes is relatively strong. This characteristic is mainly due to the dense surface layer formed during its cold drawing process. During the cold drawing process, the surface of the steel pipe is subjected to compression and stretching by the mold. This processing method helps eliminate small surface defects such as cracks, burrs, etc., thereby...

Advantages of precision cold drawn steel pipes

2025-03-25

Precision cold drawn steel pipes have the following advantages:high-precision:Accurate size control: The cold drawing process uses molds to pull steel pipes through multiple passes, improving the accuracy of the inner and outer diameter dimensions of the steel pipes. The tolerance can be controlled within ± 0.05mm, and the wall thickness uniformity reaches over 98%, far superior to hot-roll...
