Abstract
A high temperature resistant gasket assembly comprises a metallic sheet member defining a plurality of openings, including at least two bolt holes through which bolts are adapted to pass and at least one high pressure opening for surrounding a high pressure zone to be sealed. The metallic sheet member defines a surface zone adjacent the high pressure opening. A metallic wire is disposed on a surface zone of the metallic sheet member closely adjacent to the high pressure opening to effect a seal at the surface zone. Preferably, the metallic sheet is of a low carbon steel and the wire is a copper wire. A second metallic sheet member of substantially the same shape, form and material as the metallic sheet member may be positioned to overlie the metallic wire, and to confront the first sheet member to form a sandwich with the wire between the sheet members. The second sheet member has a second surface zone complementary to the first surface zone. The gasket assembly may be precompressed so that the wire is significantly embedded into each surface zone to provide a sealing zone of high sealing stress adjacent the high pressure opening. The metallic wire may be shaped to surround the high pressure opening.
