What is a Welded Steel Pipe? About Welded or ERW Steel

Mar 12,2019·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.
