Abstract
A wellhead housing includes a metal seal with a ring portion and a rib portion. The ring portion includes two frustoconical surfaces for mating with tapered surfaces of a wellhead connector and the wellhead housing. Two conical, metal-to-metal seals are created where the ring portions of the seal engage the tapered surfaces of the wellhead connector and housing. These metal-to-metal seals contain internal pressure within the wellhead. Two legs extend outward from the rib portion. An upward-facing foot surface at the end of the top leg engages the wellhead connector, while a downward-facing foot surface at the end of the bottom leg engages the wellhead housing. A metal-to-metal seal created between each foot surface and the corresponding tubular member resists external pressure to prevent water ingress into the joint.
