Abstract (en)

[origin: CA3022649A1] The invention relates to a method for producing a curved tubular connection element, having at least the following production steps: machining a linearly running metal tube piece (10) with a specifiable length while incorporating connection geometries (12, 14) for receiving separate connection parts (18, 20) which are used to connect a media-conducting piping; carrying out a bending process for the tube piece (10), which is produced by being machined in the aforementioned manner, with a specifiable bending radius, preferably up to 90 degrees; and attaching each connection part (18, 20) to the respective end-face tube piece (10) connection geometry (12, 14) which can be paired therewith.
