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.
