摘要:
A metal to metal seal and method including a first sealing member and a second sealing member, wherein the first and second sealing members are attached together to form a cylindrical sealing device; a first sealing surface and a second sealing surface on the first sealing member and the second sealing member, wherein the first and second metal sealing surfaces form a metal to metal seal with an internal cylindrical sealing surface and an external cylindrical sealing surface respectively; a transverse facing recess positioned between the first and second metal sealing surfaces; a nonmetal seal received in the transverse facing recess; and at least one pressure communication hole on each of the first and second sealing members, wherein the nonmetal seal is in fluid communication with the pressure communication holes, and a pressure differential across the sealing device energizes the nonmetal seal.
