ABSTRACT:
A process is provided for producing a connecting flange (32) for a butt joint on an end of a pipe section (10) of sheet metal with circular or oval cross section. The process includes sliding a pipe piece over the outer side of a pipe section (10), so that the pipe piece forms on the outer side of the pipe section (10) a reinforcing ring (47) lying flush against the pipe section (10) and bending the one end of pipe section (10) and the end of the reinforcing ring lying thereupon, from the pipe wall (12) outwards, to form a projecting ring rim (14) in the pipe section (10) and to form a flank (44) in the reinforcing ring (47). The flank (44) of the reinforcing ring (47) can lie against at least the radially inner part of the projecting ring rim (14), thereby forming the connecting flange.
