Abstract

L'invention concerne un conduit formé, à utiliser pour la production de pétrole ou de gaz, ledit conduit (120) comprenant un tube intérieur et un tube extérieur coaxial avec le tube intérieur. L'invention concerne un élément de chauffe (125) fixé à la surface extérieure du tube intérieur, et au tube extérieur appliqué sur le tube intérieur, et permettant un chauffage lors de l'extrusion. Le tube intérieur est formé comme un extrudat. L'élément de chauffe (125) présente une forme longitudinale sensiblement plane, et enveloppe le tube intérieur. Une couche imperméable au gaz est formée sur le tube extérieur, par le biais de l'enveloppement d'un ou de plusieurs feuilles imperméables au gaz longitudinales sensiblement planes, autour du tube extérieur.
