The Difference between ERW Steel Pipe and UOE Steel Pipe

There are five points difference about ERW Steel Pipe and UOE Steel Pipe:

1. The raw materials is different: the material for producing ERW steel pipe is hot rolled coil or strips, while UOE is hot rolled steel.

2. Different production capacity: ERW steel pipe has high production efficiency and low production costs, it can achieve a continuous pipeline operations. For UOE steel pipe, it produce lower and has high production cost. The maximum thickness of ERW steel pipe can reach 25mm, and outside diameter can achieve 660mm. However, UOE steel pipe is 40mm and outside diameter is 1422mm, it is limited by the width of the steel sheet.

3. Different application: ERW Steel Pipe is mainly used in natural gas, refined oil, crude oil and other terrestrial long-distance pipelines, UOE steel Pipe is mainly applied in high-voltage submarine long-distance pipelines, alpine area.

4. Welding difference: Compared with UOE steel pipe, one of the advantages of ERW steel pipe is that during the welding process, there is no need to have additional wire.

5. Different appearance: ERW steel pipe requires outside and inside welds remove, so it is anti-corrosive.
