Abstract

Dans ce tube de cheminée, les éléments sont raccordés par un joint à brides spécial ou un manchon de raccordement spécial. Ce joint à brides sert également à fixer le couvercle sur les ouvertures de visite du tube de cheminée et des séparateurs de condensat sur le tube de cheminée. De plus, il peut être combiné avec un piège à condensat. Le manchon de raccordement permet sur le chantier de relier des éléments de tube profilé flexibles à d'autres éléments semblables ou à des pièces profilées en évitant d'avoir recours au procédé complexe du soudage en bout à l'aide de réflecteurs. Les brides (1, 2) du joint à brides sont du type à nervures. La bride (1) et la contre-bride (2) sont reliées par des pinces (10) en plastique. Entre la bride (1) et la contre-bride (2) une bague d'étanchéité (22) en silicone, EPDM, Viton ou en tout autre matériau approprié est insérée dans une rainure préfabriquée. Les pinces (10) en plastique peuvent être remplacées par un collier tendeur de type commercial.
