Resistance Welded Pipe ERW
Resistance welded pipe ERW is formed by hot rolled coil through forming machine. The skin effect and proximity effect of the high frequency current are used to heat and melt the edges of the tube blank.
Resistance Welded Pipe ERW Description
ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape and are used in various engineering purposes. They are round pipes welded from steel plates with longitudinal welds. Pressure welding is carried out under the action of squeeze rollers. The production process of welded steel pipes is simple, the production efficiency is high, the varieties and specifications are many, and the equipment is few, but the general strength is lower than that of seamless steel pipes. ERW pipes are commonly used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure.
