Abstract: A flange connection has two pipe ends (1?, 2?, 51?, 52?) on each of which one flange (1, 2, 51, 52) is disposed and which have flange faces (11, 11?, 61, 61?) and a centering ring (33, 34) with an elastomer sealing ring (14) in contact with the ring. Both flanges include a mechanism for the detachable clamping against one another such that the flange faces (11, 11?, 61, 61?) are in contact on the centering ring and thereby are held at a predetermined flange distance (10, 60, D). The elastomer sealing ring (14) is pressed on the flange faces (11, 11?, 61, 61?) in the direction of the pipe axes (15) forming a seal, wherein the centering ring (33, 34) is positioned such that it is at least partially in contact on the periphery of the flanges (1, 2, 51, 52).
