Welded steel pipe (steel 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. Steel Pipe can be divided into Cold Drawn Smls Steel Pipe Hot Rolled Smls Steel Pipe Galvanized Steel Pipe. Features of ERW pipe Low cost: the low raw material cost and manufacturing cost make it prices more competitive than longitudinal seam submerged-arc welded pipes and seamless pipes. High Weld Seam Security: As a result of special welding method of melting parent metal together, without filler metal, the weld property is better than submerged-arc welded pipes; and the weld seam is much shorter than spiral seam welded pipes, the seam security is greatly improved. Wide Range: ERW pipes can be applied with a wide range of thickness / diameter ratio, covering hundreds of specifications. Product Name …
