Abstract
A flange coupling system for connecting pipes in an aircraft, comprises a first flange element and a second flange element, each flange element comprising a flange ring surrounding an opening for transporting a liquid or gaseous medium. Each flange ring comprises a sealing surface for mutual connection of both flange elements. Each flange element comprises one or more fixation members configured for mutual fixation of both flange elements so that their sealing surfaces are pressed against each other in a sealing plane. The fixation members of both flange elements are arranged in a way that both flange elements are fixed to each other in a fixation plane which is located away from the sealing plane.

A flange coupling system for connecting pipes in an aircraft, comprising:
- a first flange element comprising a first flange ring and a second flange element comprising a second flange ring,
- each flange ring surrounding an opening for transporting a liquid or gaseous medium,
- wherein each flange ring comprises a sealing surface for mutual connection of both flange elements,
- wherein each flange element comprises one or more fixation members configured for mutual fixation of both flange elements so that the sealing surfaces are pressed against each other in a sealing plane,
- wherein the one or more fixation members of both flange elements are configured such that the first and second flange elements are fixed to each other in a fixation plane which is located away from the sealing plane, and
- wherein the first and second flange elements are fixed to each other by fasteners which have axes that are arranged parallel to, and arranged at a radial distance from, a center axis of the first and second flange rings, such that the radial distance is smaller than a radial extension of the first and second flange rings.
