ERW Steel Pipes
Brief Introduction of ERW steel pipe
ERW pipe, short for electronic resistance welded pipe, is manufactured by cold forming the steel coil into a round cylindrical pipe. Current passes between the two edges of the steel to heat the steel to a point at which the edges are able to connect together to form a bond using the actual welding process. ERW is normally used to transport liquid, such as petrol and gas, playing a significant role in the world line pipe transporting area.
