New In tube end forming practices -- Can I downsize and then upsize a pipe end?

SUMMARY

In tube end forming practices, it is feasible to first reduce the diameter of a Ferritic Steel pipe (0.9mm thick, 55mm OD) to 50.6mm ID and then expand it by 1mm at the same end, utilizing an 8mm transition radius. This method allows for effective manipulation of the pipe's dimensions while maintaining structural integrity. For further insights, resources such as Trick Tools' end forming and swaging dies are recommended.

PREREQUISITES
  • Understanding of tube end forming techniques
  • Familiarity with Ferritic Steel properties
  • Knowledge of transition radius implications in metal forming
  • Experience with dimensional tolerances in pipe manufacturing
NEXT STEPS
  • Research advanced tube end forming techniques
  • Explore the properties and applications of Ferritic Steel
  • Learn about transition radius effects in metalworking
  • Investigate dimensional tolerance standards in pipe fabrication
USEFUL FOR

Manufacturing engineers, metal fabricators, and anyone involved in tube end forming processes will benefit from this discussion.

In tube end forming practices, is it possible to first reduce the diameter of the pipe (tube 0.9mm thick) and then expand it, at the same end, by about 1mm in total, with a transistion radius of 8mm ?
Please see attached image. Though it might be exaggerated, but the image should suffice.
I want to know the feasibility of it.
Material is Ferritic Steel. Of diameter 55 OD. The sizing is
1: Reducing to 50.6 ID and then
2. Expanding by 1mm diametrically.

Thank You.
