Method for manufacturing a double-walled heat exchange tube with leak detection, wherein an inner tube is slipped into an outer tube, after a surface profiling has been provided on at least the outer surface of the inner tube or the inner surface of the outer tube, and at least the outer surface of the inner tube or the inner surface of the outer tube has been provided with a layer of soldering material. After the tubes have been slipped into one another, the inner tube is expanded such that the outer tube is expanded as well and the surface profiling forms a leak detection channel between the two tubes, and the soldering material between inner and outer tube is caused to melt. In a heat exchange tube thus obtained, at the location of the contact between the inner and outer tube, a film-thin, optionally porous layer from soldering material is present, which layer is bonded, through melting, to both the inner tube and the outer tube.

La présente invention concerne un procédé de fabrication d'un tube d'échange thermique à double paroi et détection des fuites, procédé selon lequel on glisse un tube intérieur à l'intérieur d'un tube extérieur, après avoir effectué un profilage superficiel sur au moins la surface extérieure du tube intérieur ou la surface intérieure du tube extérieur, et après avoir déposé une couche d'un matériau de soudage sur au moins la surface extérieure du tube intérieur ou la surface intérieure du tube extérieur. Après avoir glissé les tubes l'un à l'intérieur de l'autre, on dilate le tube intérieur de façon que le tube extérieur se dilate également, le profilage superficiel formant un canal de détection des fuites entre les deux tubes, et on provoque la fusion du matériau de soudage situé entre les deux tubes. Dans le tube d'échange thermique obtenu, à l'emplacement de contact entre le tube intérieur et le tube extérieur, se trouve une couche mince comme un film, facultativement poreuse, du matériau de soudage, couche qui est liée, via la fusion, tant au tube intérieur qu'au tube extérieur.
