Process:

The cold drawn welded tube is produced by drawing ERW (electric resistance welded tube) through a die and over a mandrel plug.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.

Tube Finishing Options:

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:Drawing, Heat treatment, Bulging, Swaging, Cutting, Deburring, Vibro cleaning, Threading,De-rusting, Chamfering, Washing.

Surface treatment: Oiled, black painted, hot dipped galvanized or phosphate coating as required.
