    ELECTRIC RESISTANCE WELDING - Leaders in steel tube and erw welding steel tubes

    ERW Steel Tubes ERW (electric resistance welding) steel tube is one of the most commonly found types of tube in the market. The manufacturing process consists of roll-forming a strip of steel into a tubular section and then subsequently welding the edges together using electric resistance to first heat up the edges and then subsequently forging them together.Electric resistance welding at a glance - The FABRICATORJun 13, 2002 · Several electric resistance welding (ERW) processes are available for tube and pipe production. While each process has different characteristics, all ERW processes have one thing in commonall of them produce a forged weld. A forged weld is created by applying a combination of heat and pressure, or forging force, to the weld zone.Carbon Steel Pipe, Erw Steel Pipe, Welded Steel Pipe erw welding steel tubesHigh-frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were nerw welding steel tubes

    Differences between ERW Steel Pipe and HFW Steel Pipe

    The high frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Direct current welding is generally used for small caliber steel tubes. In general, HFW is one of ERW production methods, it adopts the high frequency welding process. So, ERW steel pipe includes HFW steel pipe.Difference between Seamless & ERW Stainless Steel pipeERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24 OD.

    ERW Pipe | Electric Resistance Welded

    ERW Pipe. 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.ERW Tubing | Sharon TubeERW Tubing.
