ERW Steel Pipe is made from a ribbon of steel that is dragged through a series of rollers and moulded into a tube that is fused with an electric charge. It is mostly utilized for low/medium pressure applications such as water/oil transportation. This is very easy to install as well as simple to use. ERW Steel Pipe is formed of steel coil with a parallel weld seam. Because the coil's breadth is the same as the pipe's circumference, diameters are restricted to 24 inches.
