Descriptions:
Precision pipe is the carbon, alloy or stainless steel pipe with high precision sizes. Usually it has been made through hot rolling or cold drawn (cold rolling) processes. So precision pipe is a kind of seamless pipe.
It is designed with several advantages:
Inside and outside surface no oxide coating;
It could bear high pressure, no leaking;
Strict less tolerance;
Surface smooth;
No reformation in cold bending, no cracks during flaring test, and flattening test.
With these advantages it is widely used for manufacturing the pneumatic parts and hydraulic components.
1. For Vehicle (Automotive, locomotive, Construction Machinery like Concrete pump and others)
Power steering system, Shock absorber, vibration damper , engine parts and others
2. Hydraulic cylinder, Industry Jacks
3. Fitness equipment,motor casings and auto parts.
Other precision surface required devises
