Abstract

Procédé et dispositif pour la fabrication en continu de tuyaux isolés thermiquement où l'on introduit le tuyau (1) à entourer d'une masse expansée, en continu dans une cavité tubulaire formée par une installation de moulage tout en induisant l'expansion axialement au centre, le mélange de matière synthétique expansé exercant une fonction de support du tuyau (1); à la sortie de l'installation le tuyau (1) muni de la masse expansée, recçoit par extrusion une gaine en matière synthétique, expansée (11).Method and device for the continuous production of thermally insulated pipes, in which the pipe (1) to be surrounded by an expanded mass is introduced, continuously into a tubular cavity formed by a molding installation while inducing expansion axially at center, the mixture of expanded synthetic material performing a support function for the pipe (1); at the outlet of the installation the pipe (1) provided with the expanded mass, receives by extrusion a sheath of synthetic material, expanded (11).
