Manufacture Process:
According to EN10305-2 standard, Cold drawn on ERW tubes, make the tubes have high strength ,high quality, and to be seamless.
The cold rolled welded tube is produced by drawing ERW (electric resistance welded tube).During this process the sizing (wall thickness, inside and outside diameter), as well as weld integrity and surface finish is closely controlled to produce tube of the required size and mechanical property characteristics.
