<p>Flexible tubular pipe for the transport of pressurized fluids comprising an outer tubular sheath, reinforcing armour, a an inner hose or pliable tubular sheath, and possibly, at least one intermediate flexible tubular sheath, and heating means in the form of electrically conducting wires, connected to an electric power source and generating heat by the Joule effect, said wires being arranged along the length of the pipe. Said pipe comprises a plurality of electrically conducting wires (8) arranged in at least one layer (5) in which said wires are parallel to each other and spirally wound around the axis of the pipe, the layer(s) of conducting wires being placed between two of the pipe's flexible tubular sheaths, without said conducting wires being interconnected, and each of the latter resting by surface contact on the underlying tubular sheath.</p> |
