What is ERW Steel Pipe? 

In the product ERW Steel Pipe, the ERW is Electric Resistance Welded. ERW steel pipe is a type of pipe made from rolled steel sheets or coils which are then welded longitudinally along its length using the electric resistance welding process. In this process, the edges of the steel sheets or coils are heated and fused together under pressure to form the pipe.

ERW pipes are commonly used in casing and tubing, scaffolding, galvanized tube, hollow section, oil and gas line pipe, piling pipe, Structure Pipe etc. 

They are known for their high strength, durability, and relatively low cost compared to other types of pipes. ERW steel pipe comes in various sizes and thicknesses to suit different applications, and they are widely used in construction, infrastructure, plumbing, and mechanical applications.
