Precision Steel Tube Characteristics
- Special dimensional accuracy of outer and inner diameters or wall thickness
- Smooth surface resulting from drawing technology
- Defined mechanical properties
- Large dimensional variety
Manufacturing Process
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.
