STOP LOSS TOOL FOR WELLHEADS

摘要

The present application includes a tool configured to prevent bidirectional passage through a pipe or wellhead. The tool includes at least a housing and a latch. The housing is coupled to the wellhead. The housing has an interior volume in communication with an interior volume of the wellhead through an aperture. The wellhead has a central axis. The latch is pivotally coupled to the interior of the housing and oriented so as to pivot within a plane parallel to the central axis. The latch is configured to selectively enter and exit the interior of the wellhead between a first orientation and a second orientation. The tool may further include a tube to be coupled in axial alignment with the wellhead or pipe.
