Abstract
A pipe (10) for conveying a fluid, including an inner sheath (20), at least one layer (34, 36) of inner armors, arranged outside the inner sheath (20) and an outer protection sheath (22), positioned outside each layer (34, 36) of inner armors. It includes an inner fluid, received between the inner sheath (20) and the outer sheath (22). The pipe includes an intermediate polymer sheath (24), interposed between the inner sheath (20) and the outer sheath (22), the intermediate sheath (24) and the inner sheath (20) delimiting an inner annular space (26) between them for receiving the inner fluid. The inner fluid is confined in the inner annular space (26) at a pressure above 50 bars.
