Title
(EN) BIMETALLIC SEAL
(FR) JOINT BIMÉTALLIQUE
Abstract
(EN) Systems and methods include providing an annular bimetallic seal for an assembly. The bimetallic seal includes a first sealing component formed from a first material, a second sealing component formed from a second material that is different than the first material, and a joint formed between the first sealing component and the second sealing component. The bimetallic seal is configured to form a radial seal between a first assembly component and a second assembly component formed from dissimilar metallic materials. The coefficient of thermal expansion (CTE) of the first material and the second material are configured maintain the radial seal at extreme operating temperatures between the dissimilar metallic materials of the components of the assembly.
(FR) L'invention concerne des systèmes et des procédés, lesquels mettent en œuvre un joint bimétallique annulaire pour un assemblage. Le joint bimétallique comprend un premier composant d'étanchéité formé à partir d'un premier matériau, un second composant d'étanchéité formé à partir d'un second matériau qui est différent du premier matériau, et un raccord formé entre le premier composant d'étanchéité et le second composant d'étanchéité. Le joint bimétallique est configuré de façon à former un joint radial entre un premier composant d'assemblage et un second composant d'assemblage formés à partir de matériaux métalliques dissemblables. Les coefficients de dilatation thermique (CTE) du premier matériau et du second matériau sont configurés de façon à maintenir le joint radial à des températures de fonctionnement extrêmes entre les matériaux métalliques dissemblables des composants de l'assemblage.
