E355 Precision Camshaft Tube Small Outside Diameter Welded Pipe

Description:

The E355 precision camshaft tube boasts small outside diameters, crafted with precision and expertise for optimal performance in demanding applications. This welded pipe, designed for precision engineering, offers exceptional strength and durability. Its small exterior diameter ensures a compact fit, ideal for camshaft applications where space is limited. With a focus on accuracy and fine craftsmanship, this tube guarantees reliable and efficient operation in high-stress environments, making it a top choice for critical engine components.

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.

Stength Yield:

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):
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
