Spiral-welded pipe is manufactured from coils of steel that are unwound and flattened. The flattened strip is formed by right-angle rollers into a cylinder of the desired diameter.
The weld is welded under powder coating. This process is also known as Submerged Arc Welding (SAW). At the end of the spiral, a new spiral is welded to the back edge of the pipe, creating a cross seam. The pipe is cut to length and the ends are beveled if necessary.
Spiral-welded pipes are available in sizes from 600 mm to 3650 mm.
