Spiral Welded Steel Pipe

Spiral steel pipe or spiral welded pipe are other terms for the spiral pipe. Steel strip coil is used as the raw material, then formed at room temperature and welded using an automatic double wire double-sided submerged arc welding technique. It can be widely used in the production of large diameter steel pipes 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. The bare pipes do not have any internal or external protective coating.
