  • Seals containing composite non-extrusion springs
    Patent number: 5791657
    Abstract: A wellhead seal assembly for sealing between first and second pipe members comprises an annular elastomeric body having, in cross-section, a generally rectangular shape comprising a first flat radial surface, a second flat radial surface, an inner circumferential surface and an outer circumferential surface; said inner circumferential surface comprises a generally convex portion that extends from an imaginary plane connecting the inner circumferential edge of each of said first radial surface and said second radial surface; said seal assembly further comprises at least one annular, non-metallic spring member in said elastomeric body positioned generally tangentially to the intersection of either of said radial surfaces with said inner circumferential surface.
