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.
Our tubes can be additionally treated to achieve the exact finishes and ends needed by customers. These are some of the additional operations that can be performed on our tube:
