ERW stands for:
ERW (Electric Resistance Welded) pipes are a type of steel pipe that is made by continuously rolling a strip of steel into a cylindrical shape. The edges of the strip are then heated and fused together using electric resistance welding, hence the name "ERW." The welding process creates a strong bond between the edges of the strip, resulting in a seamless and durable pipe.
