发明名称 Wellhead tubular connector
摘要 Systems and methods are provided that may include employing a lockscrew to provide radial and axial force in connecting tubular members in a mineral extraction system. The lockscrew may be angled relative to the tubular members, at an angle that is greater than 0 degrees and less than 90 degrees. Further, the lockscrew may have an end portion which mates with a slot in a locking segment, and the lockscrew and locking segment may be moved from an unlocked to a locked position. In a locked position, the lockscrew exerts force axially downward and radially inward to push the locking segment against a tubular member, locking the member in place. The interconnection between the lockscrew and the locking segment may enable easier installation and may utilize parts which may be easier to manufacture. Furthermore, the angle of the lockscrew may provide improved support for tubular members.

主权项 1. A system, comprising: a locking segment having a slot that is acutely angled in a first direction relative to an axis of a tubular member in a wellhead, wherein the slot is configured to receive an end portion of a lock screw to enable rotation of the lock screw along a rotational axis that is acutely angled in a second direction relative to the axis of the tubular member, the first and second directions are crosswise to one another, the slot is configured to enable movement of the end portion of the lock screw in the first direction along the slot between first and second positions, the slot is configured to release the end portion of the lock screw from the locking segment at the first position along the slot, and the slot is configured to couple the end portion of the lock screw to the locking segment at the second position along the slot.
