Wt:0.5-10
DOM Tube-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.
Advantage (compare with seamless cold drawn tube)
Better shape
Improved quality surface
Tight Excentricity and wall thickness tolerances (the eccentric
Tube more safety
Good toughness at low temperature
USA Market: 90% of the cylinder in the USA market are produced with welded tubes
Cost fix Lengths More Cheaper
Application:
Producing camshaft
Delivery Condition:
+C No heat treatment after the final cold drawing process
