Applications of 4 inch Stainless Steel Welded Pipe:

1)Food producing equipment, particularly beer brewing, milk processing & wine making;
2)Kitchen benches, sinks, troughs, equipment and appliances;
3)Architectural paneling, railings & trim;
4)Chemical containers, including for transport;
5)Heat Exchangers;
6)Woven or welded screens for mining, quarrying & water filtration;
7)Threaded fasteners;
8)Spring

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.
