ERW (Electric Resistance Welded) steel pipe is a type of pipe made from flat-rolled steel that has been formed into a tube shape using a series of rollers. The edges of the steel are then heated and fused together using an electric current, creating a strong and durable joint. ERW steel pipe is often used for various applications such as water and gas conveyance, plumbing, construction, and infrastructure.
One of the primary advantages of ERW steel pipe is its cost-effectiveness. The process used to manufacture ERW pipe is highly efficient and requires less time and energy than other methods, such as seamless or welded pipe production. This results in a lower cost per foot of pipe, making it an attractive option for many applications.
