technique and tolerance 

 Cold drawn(rolled) precision steel pipe and the general difference between ordinary seamless steel pipe:

1, the general characteristics of ordinary seamless steel pipe is welded seam, can withstand greater pressure. The product can be very rough as cast or cold parts.

2, cold drawn precision steel pipe is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.

Cold drawn (rolled) precision steel pipe features:

1. smaller diameter.

2. High precision can be done small batch Health

3. Cold drawn (rolling) finished high precision, good surface quality.

4. Steel pipe cross-sectional area is more complex.

5. Steel pipe performance is superior, the metal is relatively dense.  

Products widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator, forklifts and the Petrol industry.

1. Hydraulic Cylinder Tube------Main products of Xinpeng,

Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and 1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.

2.SRB tube ----- used in Elevator buffer and Hydraulic Cylinder .

This kind tube have a better roughness inner the tube, ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Range: ID 50-250mm and Length can work at most 6M.

3. Cold finished tube---- Widely Used.

Processing range 30-300mm, biggest length is 11M.

Xinpeng Have passed ISo9001 verified from 2008; each tube of ours is strictly in quality control that can assure the product quality of Xinpeng.
