Title (EN) SEAL WITH LIP PROJECTIONS
(FR) JOINT D'ÉTANCHÉITÉ AVEC SAILLIES DE LÈVRE
Abstract:
(EN) Seals for mechanical couplings and fittings have sealing surfaces with one or more projections that form closable leak paths between the coupling or fitting and pipe elements being joined. The leak paths close when the coupling or fitting is properly installed. Otherwise, the leak paths remain open to ensure that improperly installed couplings and fittings can be discovered during pressure testing and before service pressure is applied.
(FR) L'invention concerne des joints d'étanchéité pour des accouplements et des raccords mécaniques, lesquels joints ont des surfaces d'étanchéité avec une ou plusieurs saillies qui forment des trajectoires de fuite pouvant être fermées entre l'accouplement ou le raccord et des éléments de tuyau qui sont réunis. Les trajectoires de fuite se ferment quand l'accouplement ou le raccord est correctement installé. En variante, les trajectoires de fuite restent ouvertes pour assurer que des accouplements et des raccords installés de manière incorrecte peuvent être découverts pendant un essai de pression et avant qu'une pression de service ne soit appliquée.
