Abstract
A pipe of an air duct including, 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.

A pipe of an air duct extending between upstream and downstream ends and comprising:
- an internal layer,
- at least one insulating intermediate layer mounted on the internal layer, and
- an external layer mounted on the insulating intermediate layer,
- at least one of the upstream or downstream ends being configured to be connected to a connection system,
- wherein the pipe comprises an upstream pipe coupling positioned at a level of the upstream end and a downstream pipe coupling positioned at a level of the downstream end, such that the upstream and downstream pipe couplings are distinct from the internal layer,
- wherein each of the upstream and downstream pipe couplings include a tubular body which extends between first and second ends and has a first end section that extends from the first end and cooperates with the internal layer in sealed manner and a second end section not covered by any of the layers that extends from the second end and is configured to cooperate with the connection system,
- wherein an interior surface of the tubular body is oriented toward a central axis of the pipe, such that the tubular body increases in thickness between each of the first and second ends and a central portion of the interior surface, and
- wherein the pipe comprises a plurality of longitudinal stiffeners connecting the upstream and downstream pipe couplings positioned between the internal and external layers.
A pipe of an air duct extending between upstream and downstream ends and comprising:
- an internal layer,
- at least one insulating intermediate layer mounted on the internal layer, and
- an external layer mounted on the insulating intermediate layer, wherein the external layer is a shrink film,
- at least one of the upstream or downstream ends being configured to be connected to a connection system,
- wherein the pipe comprises an upstream pipe coupling positioned at a level of the upstream end and a downstream pipe coupling positioned at a level of the downstream end, such that the upstream and downstream pipe couplings are distinct from the internal layer,
- wherein each of the upstream and downstream pipe couplings extend between first and second ends and include a first end section that extends from the first end and cooperates with the internal layer in sealed manner and a second end section not covered by any of the layers that extends from the second end and is configured to cooperate with the connection system, and
- wherein the pipe comprises a plurality of longitudinal stiffeners connecting the upstream and downstream pipe couplings positioned between the internal and external layers.
