ERW steel pipe is flatten then place it into roller to form a tube and passes through a welding electrode made of copper disk which is connected to a revolving transformer. When the electrodes contact each side, the temperature is increased to the welding point. Once the tubes leaves the electrodes, the inside flash is removed by after colling the tube with a hammer and the outer flash by a cutting tool. The surface finish could be either bare or coated. erw steel pipe is used in fencing, line pipes, oil country tubular, scaffolding, water and gas conveyance, structural, engineering purpose. There has been a tremendous increase in the production of ERW steel pipe due to growing demand in oil & gas industry, infrastructure and automobile usages.
