Main Data
Material: E355
Other material available: E235
Standard: EN10305-2
Technique: Cold Drawn
OD: 6-80 mm
WT: 0.5-10 mm
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.
Advantages (Compared with Seamless Cold Drawn Tube)
- Better shape
- Improved quality surface
- Tight eccentricity and wall thickness tolerances
- 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
