Abstract:
1. A flange connection with two pipe ends ( 1 ′, 2 ′, 51 ′ 52 ′) with pipe axes ( 15 ), on each of which one flange ( 1 , 2 , 51 , 52 ) is disposed, which, in the direction radial to the pipe axes ( 15 ) include flange faces ( 11 , 11 ′, 61 , 61 ′) and are positioned opposite one another, comprising: a centering ring ( 33 , 34 ) enclosed by the flange faces, an elastomer sealing ring ( 14 , 54 ) that is at least partially in contact with the centering ring, both flanges ( 1 , 2 , 51 , 52 ) comprising means for the detachable clamping of the two flanges ( 1 , 2 , 51 , 52 ) against one another such that the flange faces ( 11 , 11 ′, 61 , 61 ′) are in contact on the centering ring ( 33 , 34 ) and thereby are held at a predetermined flange distance ( 10 , 60 , D) and the elastomer sealing ring ( 14 , 54 ) is pressed on the flange faces ( 11 , 11 ′, 61 , 61 ′) in the direction parallel to the pipe axes ( 15 ) forming a seal, and 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 ) and in the radial direction to the pipe axes ( 15 ), and that thereon are disposed annularly inwardly directed bearing means ( 18 ), about which the elastomer sealing ring ( 14 , 54 ), formed to be 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.
