ABSTRACT:
Butt joint between two thin-walled round sheet metal pipe sections. The butt joint has a flange ring (14) with a triangular hollow section at each pipe end (10); said hollow section has a slit (26, 26') at its radially inner side, into which the radial annular edge (12), flanged at pipe end (10), is inserted. As a result, the annular edge (12) is prevented from getting caught in the opposite pipe end (10) and, at the same time, a firm fit of the flange ring (14) is guaranteed on the appropriate pipe end (10).
