The invention relates to a method for producing a flexible tubular conduit (10) for transporting hydrocarbons, and to a flexible tubular conduit produced thereby. Said method is of the type comprising the following steps: a) a thermoplastic fluoropolymer that can be shaped in the melted state is supplied; b) said fluoropolymer is shaped in the melted state in order to produce a sealed tubular sheath (12) having an inner wall (21); and, c) armouring wires are spiralled around said sealed tubular sheath (12) in order to form an assembly of layers of armouring wires (14, 16, 18); while the inner wall (21) is left free. |
