ERW Steel Pipe, Electric Resistance Welded Pipe

ERW Pipe (Electric Resistance Weld) is manufactured by rolling a steel billet or steel belt into a tube then welding it with high frequency currents. Due to the simple processing method and cheap raw materials, this product is a very economical type and is most popular in the market. It is generally seen in low-pressure fluid transportation for water, petro, natural gas as well as other projects in drilling, offshore platform, shipbuilding, chemistry industry, construction, electrical engineering and more.
