<p>The invention relates to a method and a facility for manufacturing rigid tubular pipes having a double casing for hydrocarbon transport. The pipes include an inner rigid tube (42, 242, 342, 442) that is inserted into an outer rigid tube (16, 216, 316, 416), said facility including a supporting frame (12, 212, 312, 412) for an inlet end of said outer rigid tube and a movable apron (22, 222, 322, 422). Said apron includes a catching means (38, 238, 338, 438) capable of catching said inner rigid tube and inserting same in said outer rigid tube. According to the invention, said apron includes storage members (68, 268, 368, 468) for receiving stored heating cables (69, 269, 369, 469), and the driving force of said apron makes it possible to deploy a portion having the length of the stored heating cables (69, 269, 369, 469) so as to be able to apply said deployed portion, having the length of the heating cables, along said inner rigid tube (42, 242, 342, 442).</p> |
