| 摘要 |
The invention concerns a flexible tubular pipe (1) comprising at least, from inside outwards, a structural frame made of clipped strip (3), an inner sealing sheath (4), a cylindrical arch (5) produced by short-pitch helical winding of a clipped metal wire, at least a long-pitch wound traction armour layer (7) and an outer protective and sealing sheath (8). The invention is characterised in that a wire (9) is short-pitch wound on the armour layer (7) so that its deformable sheath (11) partly penetrates into the interstices (12) of said layer. |
