Spiral-welded pipe is produced from coils of steel that are unwound and flattened. The flattened strip is formed by angled rollers into a cylinder of the desired diameter. Interior and exterior SAW seal the spiral seam. At the end of the coil, a new coil is butt-welded to the trailing edge of the pipe, forming a cross seam.

The pipe is cut to length and the ends are beveled if required. Spiral-welded pipe is primarily used for water distribution service. Spiral-welded pipe is available in sizes from 24 in. (60 cm) to 144 in. (365 cm).
