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). A bearing mechanism (18) is disposed thereon, annularly directed inwardly, about which the
elastomer sealing ring (14), which is U-shaped in cross section, is disposed such that on the side flanks of the U-shape, on both sides, an annular areal flange
contact zone (6, 6′, 56, 56′, B) is formed.
