Peeling of polypropylene and various kinds of deformations, the application of a torque load, tensile, compressive can lead to leaks through the interface between the housing and the embedded element. Water seepage may not occur immediately after installation, but after 3 to 5 years of operation, since polypropylene is slowly but still aging. As a result of this, the micro-gap between the embedded element and the housing polypropylene may increase.

Abstract

L'invention concerne un élément de raccord de tuyauterie. L'élément de raccord de tuyauterie permettant de raccorder un tuyau de polypropylène et un tuyau métallique comprend un corps creux fabriqué dans du polypropylène et comporte un élément monobloc dans lequel un orifice donne dans la cavité du corps, et également un élément incorporé se présentant sous la forme d'une douille en alliage métallique présentant une section tubulaire encastrée dans le corps et une section tubulaire saillante. La cavité de l'élément incorporé communique avec la cavité du corps. L'extrémité de la section encastrée dans le corps de l'élément incorporé comporte une rainure annulaire ménagée adjacente à une surface interne et pourvue de surfaces cylindriques latérales internes, rainure à l'intérieur de laquelle un élément annulaire, conçu dans un matériau d'étanchéité flexible, solide, est accouplé à une base et est comprimé à une pression correspondant à une pression de compression du corps. Le résultat technique se traduit par un élargissement de la gamme de raccords de tuyauterie, avec la possibilité de raccorder simultanément un tuyau de polypropylène et un tuyau métallique, et également par une augmentation de la durée de vie des tuyaux en réduisant la probabilité d'occurrence de fuites.
