Precision steel tubes are characterized by:special dimensional accuracy of outer and inner diameters or wall thickness smooth surface resulting from drawing technology defined mechanical properties large dimensional variety
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.
Packaging Details:
Original packaging according to the customers Export standard
package in bundled or as required.
