Key Processes in Manufaturing the Precision Steel Pipe

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.

Key processes in manufacturing the precision Steel Pipe

During manufacturing processes, they key point is to do the annealing for raw materials.

Precision steel pipe manufaturing flow chart:

Raw Material Inspection- Remove Oxide Layer- Visual Ispection- Heating- Hot Rolling- Pickling and Passivation(Phosphating)- Grinding

- Lubrication and Drying- Cold Rolling (Internal and external extraction) - Remove Oil - Ends Cutting - Inspection- Marking - Packing and

Storage.

As we know, most of precision steel pipe has cold drawn and hot rolled process. On the contrast,cold rolling will be more complicated. Not only

the pipe need to be continuous rolled by three roller, but also the test have to be done after extrusion, so to guarantee the quality of the

precision pipe materials.

Manufacturing methods of seamless precision pipe includes hot rolling and cold drawn. More over it could be manufatured in welding processes.
