Abstract:
A high pressure metal-to-metal seal utilizes an expandable metal seal element able to withstand caustic fluids, high pressure, and high temperature. The metal-to-metal seal assembly is resilient for repeatable sealing and comprises an energizing metal ring and a metal sealing ring. Engagement of these two rings expands surfaces of the metal sealing ring to create inner and/or outer metal-to-metal seals.
