Abstract
Official abstract text for this publication.
A method for forming a fluid tight seal is disclosed. The method may make use of a first component having a first sealing surface, and a second component having a second sealing surface. The method may further involve coating one of the first and second sealing surfaces with a metallic film layer adapted to transform into a liquefied metallic layer when a temperature of one of the first and second surfaces exceeds a melting temperature of a metal used to form the metallic film layer. Once it becomes liquefied, the liquefied metallic layer forms a pressure-tight seal between the sealing surfaces.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for forming a dynamic beam seal coupling device, the method comprising: arranging a first tubular component having a first generally planar sealing surface and a second tubular component having a second generally planar sealing surface, wherein said first and second sealing surfaces are in facing relationship with one another when said first and second tubular components are coupled together; applying a metallic film layer to one of said first and…
