Production process of stainless steel pipes

The production process of stainless steel pipes generally includes the following steps:

Raw material preparation: Usually the raw material of stainless steel pipes is stainless steel coils, and the raw materials need to be inspected and cleaned before production.

Bending and shearing: The stainless steel coils are bent and cut by bending equipment and shearing machines to obtain pipe blanks with the required length and shape.

Welding: The pipe blanks are welded by high-frequency pipe welding machines or seamless pipe welding machines to form an integral pipe body.

Cold drawing or cold rolling: The welded pipe body is cold drawn or cold rolled to meet the precision and surface requirements of the stainless steel pipe.

Annealing: The stainless steel pipe is heat treated by an annealing furnace to improve its mechanical properties and corrosion resistance.

Polishing: The stainless steel pipe is polished to achieve a certain smoothness and glossiness on the surface.

Inspection and packaging: Finally, the produced stainless steel pipes are quality inspected and packaged, ready to be sent to the client for use.
