Abstract

Insert d’extrémité de conduit L'invention concerne un ensemble comprenant un conduit (30) dans lequel est destiné à circuler un fluide et un insert d’extrémité de conduit (11), ledit insert comprenantun élément linéaire (21) enroulé en hélice et définissant un jeu d’au moins deux et d’au plus quinze boucles (16-20) s’étendant entre une première et une deuxième extrémités, la première extrémité étant située davantage vers l’intérieur du conduit que la deuxième extrémité,dans lequelle jeu de boucles comprend au moins une boucle (16-19), dite boucle de grand diamètre, à l’intérieur du conduit et dont le diamètre externe lorsque l’insert est sorti du conduit est strictement supérieur au diamètre interne du conduit, etcaractérisé en ce queune portion d’extrémité de l’élément linéaire enroulé en hélice correspondant à la première extrémité définit une boucle ouverte (20), dite boucle d’extrémité. Figure pour l’abrégé : figure 3Conduit end insert The invention relates to an assembly comprising a conduit (30) in which a fluid is intended to circulate and a conduit end insert (11), said insert comprising a linear element (21) wound in a helix and defining a set of at least two and at most fifteen loops (16-20) extending between a first and a second end, the first end being located more inwardly of the duct than the second end, in which set of loops comprises at least one loop (16-19), called a large diameter loop, inside the duct and whose external diameter when the insert is taken out of the duct is strictly greater than the internal diameter of the duct, and characterized in this tail end portion of the helically wound linear element corresponding to the first end defines an open loop (20), called an end loop.
