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):
1.Better shape
2.Improved quality surface
3.Tight Excentricity and wall thickness tolerances (the eccentric
4.Tube more safety
5.Good toughness at low temperature
6.USA Market: 90% of the cylinder in the USA market are produced with welded tubes
7.Cost fix Lengths More Cheaper
Application:
Producing camshaft
Delivery Condition:
+C No heat treatment after the final cold drawing process
