Abstract

L'invention se rapporte aux conduites de transport de fluides chauds. La conduite est constituée de deux tubes métalliques 1 et 2 maintenus coaxiaux, le tube intérieur 1 constituant le conduit de transport proprement dit et le tube extérieur 2 étant au contact du terrain et protégé contre la corrosion par protection cathodique. L'espace intertubulaire 4 renferme le fluide calorifuge. Application au transport d'huiles ou de fuels.The invention relates to pipes for transporting hot fluids. The pipe consists of two metal tubes 1 and 2 kept coaxial, the inner tube 1 constituting the actual transport conduit and the outer tube 2 being in contact with the ground and protected against corrosion by cathodic protection. The intertubular space 4 contains the heat-insulating fluid. Application to the transport of oils or fuels.
