Patent

CA 2252383

The invention relates to a process for manufacturing individual pipe sections of a pipe system comprising a product pipe (1) and at least one duct (5) accompanying the product pipe (1), said product pipe (1) and said duct (5) being provided with an insulation (3) surrounded by a jacket pipe (2). The following procedural steps are proposed to produce practically any duct layout along the product pipe (1) in a simple and economical manner: (a) arrangement of at least one core (7) having at least the external contour of the duct (5) in such a manner on the outer surface of the product pipe (1) that the duct (5) formed by the core (7) is open with respect to the product pipe (1) at least in a linear manner along the length of the duct (5); (b) insertion of the unit comprising the product pipe (1) and the core (7) into the jacket pipe (2); filling of the free duct cross-section of the jacket pipe (2) with insulating material which can only flow when in the processing state.

L'invention concerne un procédé de production de tronçons individuels d'un conduite constituée de tuyaux (1) destinés à l'écoulement d'un produit et d'au moins un canal (5) s'étendant le long dudit tuyau (1), le tuyau (1) destiné à l'écoulement d'un produit et le canal (5) étant pourvus d'une isolation (3) entourée d'une enveloppe (2). Pour permettre l'obtention, de façon simple et bon marché, de presque n'importe quel tracé du canal le long dudit tuyau (1), il est proposé un procédé comprenant les étapes suivantes: (a) mise en place, sur la surface latérale du tuyau (1), d'une partie intérieure dont la forme correspond au moins au contour extérieur du canal (5), de façon telle que le canal (5) formé par ladite partie intérieure (7) soit ouvert sur toute sa longueur et forme une ligne du côté dudit tuyau (1); b) introduction de l'ensemble constitué du tuyau (1) et de la partie intérieure (7) dans l'enveloppe (2); et c) remplissage de la section libre du canal dans l'enveloppe (2), avec une matière d'isolation qui ne peut couler qu'au moment où elle est travaillée.
