Applications of Stainless Steel Pipe: 

1).Petroleum, Chemical enterprise, superheater of boiler, heat exchanger

2).High temperature resistant transmission fluid pipe in power station

3).Ship with pressure pipe

4).The exhaust purification device

5) Construction and ornament

Annealing of mother tuber ensures:

A) Removal of stress induced during tube forming and cold drawing:

B) Sufficient ductility and softness for cold drawing:

C) Transformation of the weld zone to austenitic nature,

D) Re crystallization of metallic grains to original form and thereby improving corrosion resistance.

The tubes are then coated with proper lubricant and then cold drawn over a drew bench:

1) To vary the metallurgical structure and restore the properties to the parent material:

2) To achieve a tube having closer dimensional tolerances:

3) To achieve a tube having closer dimensional tolerances:

4) To produce tubing of smaller size and wall thickness.

5) To reorient the grain structure of weld portion with that of the parent material and

6) To remove/minimize the internal bead.
