Abstract

A remote, automatic make-up, stab-in sealing system for providing metal-to-metal seals between a projecting structure and a surrounding bore telescopically receiving the projecting structure is disclosed. The sealing system includes the projecting structure, such as a pipe hanger or pack-off nipple. The sealing system further includes apparatus having the bore for receiving the projecting structure, such as a wellhead or tubing hanger. The sealing system also includes a seal assembly. The seal assembly includes at least one frusto-conical shaped metal gasket, a split ring and an actuator ring. The rings force the frusto-conical shape metal gasket into metal-to-metal sealing engagement with the walls of both the projecting structure and the bore as the projecting structure is telescopically received by the bore.
