Delivery Conditions:
+C Hard. No final treatment after final cold drawing.
+LC Soft. Final heat treatment is followed by a suitable drawing pass (limited reduction of area).
+SR Stress Relieved. After final cold drawing, the tubes are stress relieved in a controlled atmosphere.
+A Annealed. After final cold drawing, the tubes are annealed in a controlled atmosphere.
+N Normalized. After final cold drawing, the tubes are normalized in a controlled atmosphere.
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.
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.
Standard AND Optional Testing:
Visual and dimensional test 100%.
Eddy current test 100% acc. to EN 10246-3.
Ultrasonic test 100% acc. to EN 10246-7.
