摘要

Production of a coupling on a pipe (1), preferably made from copper, nickel or iron alloys comprises completely or partially compressing the region of the pipe end that is to be or has been expanded using a force acting on the pipe when and/or once the expansion tool (2) has been introduced into the pipe end. The external diameter of the pipe end that is to be processed is delimited by shaping jaws (3) that completely or partially surround the pipe end. An independent claim is also included for a device for producing a coupling on a pipe. Preferred Features: Only the region of the pipe end that is to be or has been expanded is expanded during expansion of the pipe end.
