LOCK MANDRELS

BPXNI Lock Mandrel – Interference

Used to non-selectively locate and lock into type “XN” landing nipples.

The “BPXNI” type lock mandrel has an integral collet that aids in locking the fishneck in place, this helps prevent, or mitigate the chances of a premature release of the lock mandrel from the profile nipple.

The “BPXNI” type lock mandrels utilize various equalizing assemblies depending on the desired application. 

Type “BPXNI” lock mandrels are typically used in applications where the pressure differential does not exceed 4000 psi, or 28 MpA.

 

Applications:

 

Used with various equalizing assemblies to blank off pressure of production tubing.

Used to deploy check valves, standing valves, or velocity strings in the tubing string.

Used to deploy bottom hole chokes into the tubing string.

Used to deploy or hang bottom hole instruments in the wellbore.
