Beschreibung
Zusammenfassung:	The invention relates to a duct (10) for conveying a fluid, including an inner sheath (20), at least one layer (34, 36) of inner reinforcements arranged outside of the inner sheath (20), and an outer protection sheath (22) arranged outside of each layer (34, 36) of inner reinforcements. Said duct comprises an inner fluid received between the inner sheath (20) and the outer sheath (22). The duct comprises an intermediate polymer sheath (24) inserted between the inner sheath (20) and the outer sheath (22), the intermediate sheath (24) and the inner sheath (20) defining therebetween an annular gap (26) for receiving the inner fluid. The inner fluid is confined in the annular gap (26) at a pressure higher than 50 bars.
