Automotive pipeline system;hydraulic system of diesel engine and engineering machinery;hydraulic system of locomotive, aerospace and aviation,shipbuilding and various machinery;metal processing of wind power equipment;
Advantage of Precision Seamless Steel Tubes
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.
Surface treatment:
Oil-dip;
Varnish;
Shot Blasting;
As customer's requirements.
Test:
100% Ultrasonic Detector
Eddy Current Detector
We have our own lab to control the material quility and to make sure the product meet the international standard.
