We are specilized in producing X52 seamless steel pipes for submerine transportation.
Our pipes are of high quality as they are cold shearing machine of uniform composition, high tonnage, cutting head end face smooth and neat,
While the fake seamless steel pipeis uneven, and no metallic luster.
due to poor material, cutting head face often have meat, which is uneven, and no metallic luster.

Seamless steel pipe used
1. Construction are: pipeline under most more, ground water, hot water boiler used when building and so on.
2. Mechanical processing, bearing sleeve, processing machinery parts, etc.
3. The electrical class: gas pipeline, water electricity fluid.
4. Wind farms anti-static tube, etc.
The process :
Tube billet heating - inspection - skin - - - perforation, pickling, grinding, dry lubrication, welding head, cold drawing, solid solution treatment, pickling, pickling passivation - inspection - cold rolled - oil - cutting head - dry - polishing, polishing, inspection, identification, finished product packaging
