ABSTRACT:
Method and apparatus for establishing a seal across the annulus between two concentric rigid members to seal the annulus against large fluid pressures. A specially formed seal ring, advantageously of low carbon steel in the annealed state, is preliminarily inserted into the annular space between two concentrically opposed surfaces, then forced further into that annular space to force the sealing ring, with accompanying plastic deformation of a portion of the ring, into sealing engagement with both of the concentrically opposed surfaces.
