ERW Steel Pipes is a kind of steel pipe which is formed by bending steel strip or steel plate into circular or square shape and then welded on the surface with joints. The blank used in welded steel pipe is steel plate or strip steel.

Advantages and features
Generally, ERW steel pipe has high accuracy, uniform wall thickness, high brightness of inner and outer surface of pipe (the brightness of steel pipe determined by the surface grade of steel plate), and can be arbitrarily ruled. Therefore, it embodies its economy and beauty in the application of high precision, medium and low pressure fluids. Welded steel pipe has the advantages of simple production process, high production efficiency, low cost and rapid development.
