Hydraulic system of diesel engine and engineering machinery;

Hydraulic system of locomotive.

 

Advantage of Precision Seamless Steel Tubes

1. Smaller outer diameters;

2. High precision can be done in small batch production;

3. Cold drawing finished products with high precision and good surface quality.

4. The transverse area of the steel tube is more complicated;

5. Steel pipe performance is superior, metal is more dense.
