Abstract
A wellhead connector has a tubular head that lands over a well conduit, such as casing. The head has an annular recess. An annular housing is located in the recess. The housing has a slips bowl which carries gripping segments for gripping the casing. The gripping segments have exterior wedge surfaces which are engaged by radially extending lock pins. The lock pins extend through threaded holes in the head and through holes in the housing. The housing has an exterior cam surface.
The lock pins may be removed from engagement with the gripping segments, the head picked up, and the lock pins reinserted into the holes for engaging the housing cam surface. Rotating the lock pins releases the segments from engagement with the casing.
The lock pins may be removed from engagement with the gripping segments, the head picked up, and the lock pins reinserted into the holes for engaging the housing cam surface. Rotating the lock pins releases the segments from engagement with the casing.
