Precision Tubes
Precision Tubes Description
Precision steel tube features in large size, high precision, smooth surface inside and outside, precision steel tube manufacturers produces no oxide film on the surface inside and outside of the steel tube after heat treatment, steel tube flaming, flattening without crack, cold bending without deformation, and can withstand high pressure, can do a variety of complex deformation and mechanical processing.
1. The outer diameter of precison tubes is smaller.
2. Small batch production with high precision.
3. High precision and good surface quality of cold-drawn products.
4. The horizontal area of steel tube is more complicated.
5. Steel tube performance is better, higher density.
