ERW Pipe | Electric Resistance Welded

Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, the manufacturing process is fast so it is ideal for large production runs of small (<= 24 in.) diameter sections.Submerged Arc Welding Straight Seam Steel Pipe API 5L small diameter straight seam welded pipeAnd non-straight seam welded pipe compared.
