Abstract

MONTAGEM DE VEDAçãO E MéTODO DE FABRICAçãO DE UMA VEDAçãO Uma montagem de vedação metálica para vedar componentes em ambientes altamente corrosivos, tal como um ambiente de poço sulfuroso. A montagem de vedação é compreendido de um componente estrutural de base metálica com uma camada metálica mais suave aplicada em sua superfície. O propósito dessa camada metálica suave é para localmente deformar e, desse modo, formar uma vedação contra uma superfície de um componente oposto. A estrutura de base metálica da vedação pode ser compreendida de uma liga resistente à corrosão. Em adição, a camada metálica suave pode ser compreendida de uma liga resistente à corrosão, tal como um metal refratário do tipo tântalo.SEAL ASSEMBLY AND ONE SEAL MANUFACTURING METHOD A metal seal assembly to seal components in highly corrosive environments, such as a sulphurous pit environment. The seal assembly is comprised of a metal-based structural component with a softer metal layer applied to its surface. The purpose of such a soft metal layer is to locally deform and thereby form a seal against a surface of an opposing component. The metal base structure of the seal may be comprised of a corrosion resistant alloy. In addition, the soft metal layer may be comprised of a corrosion resistant alloy, such as a tantalum refractory metal.
