The present invention relates to a method for joining spirally wound thermoplastic pipes (1, 2) of a hole profile together, characterized by the following steps: working the end surfaces (3, 4) of the spirally wound thermoplastic pipes (1, 2) into a smooth step-formed surface; setting two thermoplastic pipes (1, 2) end against end such that a smooth step-formed gap is formed between the end surfaces (3,4); applying a stainless steel band (5) over the gap and heating the steel band (5) to ca. 100 °C, applying an extruder (6) with a rotating extruder head (6) and a cooled slide and smoothing organ (8) cooperating therewith inside the pipes (1, 2) to be joined together; heating the end surfaces (3, 4); extruding a weld seam of a melted thermoplastic (9) into the gap between the two end surfaces (3, 4); as well as stopping the heating of the steel band (5) and removal of the steel band (5) from the joining place after cooling.
La présente invention concerne un procédé d'assemblage de canalisations thermoplastiques de construction hélicoïdale (1, 2) comportant les étapes suivantes : découpage des extrémités des canalisations (1, 2) pour obtenir une face régulière avec épaulement(s) (3, 4); aboutement des canalisations (1, 2) de manière à laisser un espace entre les faces d'extrémité (3, 4); mise en place d'une bande d'acier inoxydable (5) sur le joint et chauffage de la bande d'acier à une température d'environ 100 oC; insertion dans les canalisations (1, 2) à assembler d'un dispositif d'extrusion (6) à tête rotative (6) avec caniveau et organe de lissage (8) refroidis; chauffage des faces d'extrémité (3, 4) à assembler; extrusion d'une matière thermoplastique fondue (9) dans l'espace entre les faces d'extrémité (3, 4) pour former un joint; arrêt du chauffage de la bande d'acier inoxydable (5) et retrait de la bande (5) après refroidissement du joint.
