Abstract
Cet élément de tuyauterie comprend d'une part un emboîtement 10 en une polyoléfine, d'autre part une garniture Il en caoutchouc EPDM à bourrelet de serrage intérieur 13 relié par un voile souple 14 à un talon extérieur 12. Ce talon est directement soudé sur une collerette radiale 4 de l'emboîtement et possède deux lèvres 16, 17 garantissant l'étanchéité aussi bien vis-à-vis de la pression extérieure que de la pression intérieure indépendamment de la qualité de la soudure. La soudure peut se faire par ultra-sons, par transmission de chaleur à travers le caoutchouc ou au moyen d'une résistance électrique disposée à l'interface caoutchouc-polyoléfine. Application aux manchons de raccordement des tuyaux d'amiante-ciment
