Surface roughness has important impact on the performance of steel pipe

Shell fabric’s feeling would be an important reference factor for buyers who need clothes. So does for steel pipe, not matter you are seamless steel pipe, ERW steel pipe, or SSAW steel pipe.

Affected by following factors of the pipe surface roughness:

1: Wear resistance of pipe surface roughness. Generally speaking, the rougher the steel pipe's surface, with the smaller effective contact area among the mating surfaces, there is more pressure, there is more wear here!

2: Roughness stability would be affected by complex nature. For the steel pipe's surface, the rougher, the easier it is to wear. Under this situation, we should make sure the high quality of the steel pipe's roughness.

3: Pipe surface roughness would have impact for gas or liquid erosion. Rough surface is easy to make corrosive gas or liquid penetrate the inner surface of the microscopic metal, causing surface erosion.
