Abstract: A pipe comprising at least one flexible duct, wherein the pipe comprises at least one stiffening band, which is pressed against the duct over at least some of its length, extends along a longitudinal direction substantially parallel to the axis of the duct and has, at least in one state, considerable rigidity along the longitudinal direction, the stiffening band being configured to deform elastically between a rolled-up state, when the cross sections of the stiffening band are rectilinear, and an elongate and rigid state, when the cross sections of the stiffening band are curved. An aircraft comprising at least one such pipe.

Abstract: A tool for laying a sealing strip around a protruding part of a connecting element protruding from a bearing surface, the laying tool including an annular duct having an outer surface configured to delimit, with the bearing surface and the protruding part, a cavity when the annular duct is positioned around the protruding part and in contact with the bearing surface, the annular duct including at least one orifice for supplying pasty composition and outlet orifices for injecting the pasty composition into the cavity to form the sealing strip. A method for laying a sealing strip using the tool is disclosed and an aircraft with at least one sealing strip obtained using the method.

Abstract: A pipe of an air duct comprising, from the interior toward the exterior, an internal layer, at least one insulating intermediate layer, an external layer and at least at one of its ends a pipe coupling distinct from the internal layer including a first end section that cooperates with the internal layer in sealed manner and a second end section not covered by any of the layers that is configured to cooperate with a connection system. Thus, no clamp of a connection system exerts compression forces on the internal layer of the pipe, which consequently is not necessarily reinforced by means of fibers.

Abstract: A seal includes a barrel extending between a base and a top, in which the barrel has a cylindrical cavity passing through it between its base and its top, and a skirt indissociable from the barrel and extending around said barrel, in which the skirt adopts the shape of a dome of which the exterior edges extend out beyond the base starting from the top. The seal is able to divert the fluid and keep the space under the skirt fluid tight.
