发明名称 Wellhead seal with protective rib
摘要 A seal member that locates between inner and outer tubular members has ribs for reducing the amount of sliding contact. The seal member is U-shaped, having inner and outer walls connected on one end by a base. Each wall has a sealing band protruding radially outward. Each wall has a rib located between the base and the sealing bands. The ribs engage the sidewall surfaces of the tubular members during installation. Each tubular member has a recess for receiving the rib to allow the seal member walls to deflect back to the proper positions once fully installed.
