Abstract

The method involves cutting metal pipes with a defined diameter and a defined wall thickness, and folding the metal pipes to a torus. A fixed end of the metal pipe torus is welded shortly from each other. A connecting piece is mounted at the metal pipe torus for pressing an incompressible medium, and the metal pipe torus is placed in a multi-part form. The torus is pressurized with the incompressible medium, the formed torus is removed from the multi-part form, and the formed torus is separated into two sub-rings.
