摘要:
A wellhead seal assembly that forms a metal-to-metal seal between inner and outer wellhead members and a face seal between inner wellhead members. The face seal is created by two opposing sealing surfaces on inner wellhead members that sealingly engage each other. The inner wellhead members that interact to form a face seal may be a casing hanger, bridging hanger, or lockdown hanger. A wicker profile formed on one of the opposing seal surfaces bites into the opposing seal surface in response to a load. The face seal is designed such that well pressure enhances the face seal.
