Abstract

L'invention porte sur un système de branchement d'une conduite latérale sur une conduite principale présentant dans sa paroi latérale une ouverture tronconique. L'élément de raccordement de l'invention permet d'élargir la zone de jonction entre la partie tronconique et la conduite latérale, élargissement qui assure la solidité du collage et l'étanchéité lorsqu'on solidarise les deux pièce à l'aide d'une colle adaptée au matériau ou par soudage à chaud. La rigidité mécanique de la jonction peut être assurée par des vis et écrous placé dans des trous percés à cet effet, alors que le soudage assure un supplément de rigidité et l'étanchéité
