Beschreibung
Zusammenfassung:	The pipe comprises an internal sheath (20), and an unstapled pressure vault structure (27), comprising at least one metal vault wire (40) wound with a short pitch forming a plurality of successive turns (42) around an outer surface (21) of the internal sheath (20). The pressure vault structure (27) comprises at least one metal contact region applied on the outer surface (21) of the internal sheath (20), the metal contact region having, in cross-section in at least one median axial plane passing through the central axis, an inner edge parallel to the central axis. The flexible pipe comprises an assembly (27A) for indexing the axial position of each turn (42) along the central axis, suitable for maintaining a gap (47) between each pair of adjacent turns (42).
