Product Description
EN10305-2 E355 OD10 Precision Camshaft Tube Small Outside Diameter Welded Pipe
E355 Precision Camshaft Tube Small Outside Diameter Welded Pipe
Description
The E355 precision camshaft tube features small outside diameters, engineered with precision for optimal performance in demanding applications. This welded pipe offers exceptional strength and durability, with its compact exterior diameter ensuring ideal fit for camshaft applications where space is limited. Designed with accuracy and fine craftsmanship, this tube guarantees reliable and efficient operation in high-stress environments, making it a premier choice for critical engine components.
Production Method
The cold drawn welded tube is produced by drawing ERW (electric resistance welded tube). During this process, sizing (wall thickness, inside and outside diameter), weld integrity, and surface finish are closely controlled to produce tube of the required size and mechanical property characteristics.

Delivery Conditions
- +C: No heat treatment after the final cold drawing process
- +LC: After the final heat treatment there is a suitable drawing pass
- +SR: After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere
- +A: After the final cold drawing process the tubes are annealed in a controlled atmosphere
- +N: After the final cold drawing operation the tubes are normalized in a controlled atmosphere
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 cylinders in the USA market are produced with welded tubes
- Cost fixed lengths more economical
