Abstract

Pipe coupling comprises two tubular parts each having a flange at one end, a clamping ring with an internal groove adapted to receive the flanges when the two tubular parts are disposed in end to end relationship with their flanges together. The coupling includes an annular seal adapted to provide sealing between the tubular parts. At least one of the flanges, in axial section through the respective tubular part, on the side which faces away from the end of the tubular part, slopes outwards from the periphery of the tubular part towards the one end thereof. At least one side wall of the groove in the tubular clamping ring in axial section through the clamping ring, slopes towards the other side wall of the groove in a direction away from the axis of the clamping ring. When the coupling is assembled, a circumferential tension in the clamping ring produces a wedging action urging one flange into engagement, via the end face of its flanges, with the end of the other flange.
