NomenclatureConstructionAdvantagesOperationsProductsThe nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding. The strip then passes through a series of contoured rollers which cold-form the material into a circular (squarSee more on metalsupermarketsAuthor Metal SupermarketsPublished May 12, 2015Differences between ERW Steel Pipe and HFW Steel Pipe(steel) ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance.

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, because the manufacturing process is fast, it is ideal for large production runs of small (<= 24 in.) diameter sections.(plate) ERW Pipe Manufacturing Process - Sunny Steel(steel) Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
