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

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. Why does stainless steel rust after welding? - CougartronStainless Steel is Highly Resistant to Corrosion but can Still Rust.
