High Precision Automotive Steel Tubing , Camshaft Special Welded Steel Pipe
Production Method:
The cold drawn 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.

Delivery Condition:
1) +C No heat treatment after the final cold drawing process.
2) +LC After the final heat treatment there is a suitable drawing pass.
3) +SR After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere.
4) +A After the final cold drawing process the tubes are annealed in a controlled atmosphere.
5) +N After the final cold drawing operation the tubes are normalized in a controlled atmosphere.
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
Advantage of Our Company
Top class of welding line: SG/76 Enhanced High-precise High Frequency Welding Tube Production Line. The tube is of small outer diameter (D) and thick wall thickness (t): t/D≥0.2, and high size precision.
