Abstract
A device and method for the expansion-swaging of tubes into a tube plate where an expansion core is inserted into the tube and two pressure rings on the core axially delimit a radially very narrow pressure space into which a very highly pressurized fluid is introduced, thereby expanding the tube. The pressure rings are of highly pressure resistant material and are supported by abutment shoulders of inner and outer core guide portions engaging the tube with minimal clearance.
