Precision Cold Drawn Seamless Steel Tubes
The tubes are produced by cold drawing precision seamless tubes over a plug through a reducing die, achieving a reduction in outside diameter and wall thickness. The tubes are bright annealed under a closely controlled reducing atmosphere in a highly sophisticated electric heated roller hearth furnace to ensure bright, scale-free tubes free from oxidation, meeting critical end-user requirements.
The tubes are cold straightened, followed by finishing operations, inspection, packing and dispatch. Cold drawn seamless tubes have close dimensional tolerances, better surface finish, refined micro structure etc. These tubes have wide applications in hydraulics, high pressure fuel injection, General Engineering industries and process industries.
Size Range :-
Outside Diameter : 6 mm to 50.80 mm
Wall Thickness : 1 mm to 5 mm
Length of Tubes : Up to 25 Meters

Advantages Of Bright Annealed Cold Drawn Seamless Steel Tubes
Precision dimensional control tubes are free of oxides, dirt, etc. Hence simple operations like flushing with oil or compressed air will clean the remaining soot and dust particles in the tubes which will extend the life of the critical components nozzle, pumps, control valves, and others.
