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.ERW Pteel Pipe as the First Choice for Urban Gas Pipeline (6) The inner wall of the ERW straight seam welded pipe is smooth and the friction resistance is small, which avoids the precipitation of gas impurities and improves the pipeline transportation capacity; (7) It is suitable for wide temperature range, convenient construction and tight welding interface.Types of Oil & Gas PipesSeamless, ERW, LSAW ERW pipes are manufactured using steel coilsthe coil is first uncoiled, then smoothed, cut and, finally formed into a pipe shape by joining its two extremities electrically. ERW pipes are available in sizes between 1/2 and 20 inches, in carbon steel (ASTM A53 is the most common specification) and stainless steel (ASTM A312).
