Abstract

L'invention concerne un raccord comprenant un corps de matière plastique armée de fibres de verre et un manchon de caoutchouc placé à l'intérieur. Le manchon de caoutchouc est formé en une seule pièce avec des garnitures d'étanchéité d'extrémité et un revêtement de caoutchouc placé entre les garnitures. Lors de la fabrication, le manchon est étiré sur un mandrin et le corps de matière plastique armée de fibres est formé par enroulement de stratifil imprégné. L'allongement du manchon compense la dilatation thermique au cours du durcissement de la régine du corps. Application à la fabrication de raccords pour tuyauteries d'amiante-ciment.
