Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp.Welding treatment of spiral steel pipeThe spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling in multiple rollers, the strip steel is gradually rolled up to form a round tube bank with an open gap. The reduction of the squeeze roller is adjusted to control the weld gap at 1~ 3mm Welding treatment of spiral steel pipeThe spiral steel pipe feeds the strip steel into the welded pipe unit.
