Beschreibung
Zusammenfassung:	This pipe comprises a rough-bore internal carcass (26), arranged inside an internal sheath, the internal carcass (26) comprising a first folded tape (31) delimiting a helicoidal gap (40) opening toward the central axis and a helicoidal insert closing off this helicoidal gap (40) toward the inside. The helicoidal insert (28) has in cross section the shape of a lazy S, the section being taken on an axial midplane, the lazy-S-shape cross section comprising an axial exterior region (42), a radial intermediate region (44) and an axial interior region (46) projecting from the radial intermediate region (44) axially in the opposite direction to and radially some distance away from the axial exterior region (42), the axial interior region (46) at least partially closing off the helicoidal gap (40).
