Abstract: An aircraft assembly is disclosed including a rib of a wing, an aperture in the rib, and a pipe assembly extending through the aperture. The pipe assembly includes a first rigid pipe section, a second rigid pipe section and a flexible pipe section between the first and second rigid pipe sections; and a fixture arrangement that couples one of the pipe sections to the wing rib. The flexible pipe section is located at a plane of the rib and configured to allow relative movement between the first rigid pipe section and the second rigid pipe section.

Abstract: A coupling for insulated piping is disclosed having first and second parts for forming the coupling. The first and second parts include an inner conduit portion for fluid communication with an inner tube of an insulated pipe and an outer conduit portion, the inner conduit portion and outer conduit portion forming therebetween a space for fluid communication with the insulating part of an insulated pipe. In use, cold liquid is transported in the inner conduit portions. The first and second parts comprise flanges. The inner conduit portion of the first part has a projection comprising a lower thermal expansion region. The second part has a projection-receiving portion for receiving the projection of the first part, the projection-receiving portion having a co-efficient of thermal expansion that is greater than the lower thermal expansion region of the projection.

Abstract: An aircraft assembly is disclosed including a wing structure, and a pipe assembly rotatably coupled to the wing structure by a fixture arrangement.

Abstract: A coupling for vacuum-insulated piping is disclosed having first and second parts for forming the coupling; each of the first and second parts comprising an inner portion for fluid communication with an inner part of a vacuum-insulated pipe and an outer portion for fluid communication with an outer, low pressure part of a vacuum-insulated pipe; the inner portions of the first and second parts form an inner region for the passage of fluid therethrough; each of the first and second parts comprising an interface portion for forming an interface with interface portion of the other of the first and second parts, the interface portion comprising a flange for connecting the first and second parts; each of the first and second parts comprises a sleeve surrounding the outer portion, the sleeve comprising a thermally-conducting portion that is in thermal communication with the interface portion so as to conduct heat away from the interface portion.

Abstract: A fluid pipe connection is disclosed having an inner pipe assembly including a first inner pipe section and a second inner pipe section, and an inner joint between the first inner pipe section and second inner pipe section; an outer pipe assembly having a first outer pipe section, a second outer pipe section, a shroud covering the inner joint and mechanically connecting the first outer pipe section to the second outer pipe section via a mechanical connection, and a hatch fastened to the shroud by one or more fasteners and covering a hole in the shroud, wherein the hatch is moveable between a closed position and an open position to provide access to the inner joint through the hole.

Abstract: A pipe joint including an outer pipe assembly having a first outer pipe portion, a second outer pipe portion, and a shroud coupling the first and second outer pipe portions. The outer pipe joint includes an outer securing mechanism securing the shroud to the second outer pipe portion. The inner pipe assembly, within the outer pipe assembly, includes a first inner pipe portion coupled to a second inner pipe portion via an inner pipe joint. The inner pipe assembly provides an inner fluid flow path extending axially and across the inner pipe joint. The shroud is movably mounted to the first outer pipe portion, and the outer securing mechanism is releasable so the shroud can move along the first outer pipe portion and withdrawn from the second outer pipe portion to open a gap between the shroud and the second outer pipe portion for the inner pipe joint.

Abstract: A coupling for a double-walled pipe having an inner wall and an outer wall, the inner wall having an inner lumen, and the inner wall and the outer wall delimiting an outer lumen. The coupling comprises an inner section forming a passage in fluid communication with the inner lumen, and an outer section arranged radially adjacent to the inner section. A material of the outer section is interrupted in a radial direction multiple times in an area corresponding to a radial range between the inner wall and the outer wall. A further exemplary coupling may have an outer section that is interrupted multiple times in the longitudinal direction.
