  • Shape memory alloy member for use in polymer or composite seal applications
    Patent number: 10612658
    Abstract: A sealing system (100) that includes a first component (112), a second component (114) and a polymer seal (116) positioned in a seal recess (118) in the first component. A TWSMA member (122) is positioned in the seal recess (118), wherein the TWSMA member (122) has a retracted shape (122R) and an expanded shape (122E), the TWSMA member (122) transitioning from the retracted shape (122R) to the expanded shape (122E) at a temperature that is less than an installation temperature when the polymer seal (116) and the TWSMA member (122) were positioned in the seal recess (118).

  • 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.
