Spiral welded pipe is formed by bending the hot-rolled strip in a spiral shape, and welding the outer seam and the inner seam by submerged arc automatic welding to form a spiral pipe. Spiral welded pipes can be widely used in the production of large diameter spiral pipes because:

1 Spiral welded pipe can produce various diameters of spiral pipes with the same width of strip steel, as long as the forming angle is changed.

2 The length of the spiral welded pipe is not limited because of continuous bending.

3 The dimensional accuracy of the spiral welded pipe is high because the spiral shape of the welding seam is evenly distributed on the entire circumference of the spiral pipe, and the strength is also high.

4 Spiral welded pipe is suitable for the processing and production of multi-variety and small-batch spiral pipes. It is to roll low-alloy structural steel strip or low-carbon carbon structural steel into a tube blank at a certain angle of the helix, and then weld the pipe seams to produce and processed.
