Patent ID: 7530574

Claim:
A method for sealing flanged components within a high temperature, high pressure environment, said method comprising the steps of: obtaining a first component having a flange; obtaining a second component having a flange, each of said flanges being complimentary to each other; providing a dynamic flange sealing system within at least one of said flanges of said first and second components, said dynamic flange sealing system comprising: a corrugated bellow seal supported in one of said flanges of said first and second components and extending to and received by said complimentary flange upon their connection, said corrugated bellow seal being structured to be compressed between and structured to provide a dynamic seal between said first and second components; a bi-material gasket supported within one of said flanges of said first and second components, said bi-material gasket comprising a flexor, which comprises a corrugated metal generally c shaped ring and a flexible sealant partially connected to said flexor; and securing said first component to said second component via their respective said flanges, said step of securing causes said flexor to contract, wherein said flexible sealant displaces and seals against respective sealing surfaces on said flanges of said first and second components relative to the amount said flexor contracts, said dynamic flange sealing system providing a flange seal between said first and second components.
