Application

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

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.

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.
