<p>The assembly includes two tubes (110,210) whose external tube (110) surrounds the internal tube (210), forming between them a fluid circulation space, with electrical connection units (135,220) between these tubes which connect the assembly to a source of electrical power and heating the two tubes by joule effect. The electrical connectors include a conical wall (220) and a ring (135), each one mounted fixed to a different tube among the interior tube and the exterior tube, the ring supports the conical wall such that differential expansion of the two tubes generate an increase in the supporting of the conical wall by the ring.</p> |
