ABSTRACT:
The flexible pipe comprises a plastic sealing sheath and an inner plastic sheath which define an annular space in which structural elements are placed. The structural elements comprising at least one armor ply consisting of metal wires wound helically with a long pitch are in the space. An end fitting is fitted at each end of the flexible pipe. At least one external anode electronically connected to at least one armor ply. The anode is placed in an intermediate region of the flexible pipe distal from the end fittings. A connection means connects the anode to at least one of the metal wires of the said armor ply in the intermediate region.
