  • Pressure energized/pressure intensified casing seal
    Patent number: 4848777
    Abstract: A casing seal for use with a source of high pressure fluids with apparatus for preventing shredding of the seal with variations in fluid pressure. A T-shaped annular metal ring provides a multiplication of fluid pressure so pressure exerted on an elastomeric sealing ring is greater than the fluid pressure. This multiplication prevents gases from entering the elastomer and prevents shredding of the elastomer when pressure is released. The multiplication of pressure also forces the elastomer firmly against a casing and a casing head to provide a fluid-tight seal.
