Bright surface 201, 304, 316L stainless steel welded pipe at factory price

ASTM 316L stainless steel welded pipe with High Quality

Stainless steel is a production which not easy rust,acid resistance and corrosion resistance,so it is widely used in light industry,heavy industry,daily necessities and the decoration industry.my company long-term supply stainless steel products including:stainless steel sheet,stainless steel coil and stainless steel tube.

Packaging:

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.

Drawing is followed by subsequent annealing and pickling to restore the properties of the entire tube to that of the parent material. The tubes are then posited to impart extra corrosion resistance. Thereafter every tube is electrically marked with material grade, size and manufacturing standard.
