X／XN PROFILE LOCK MANDREL

X PROFILE LOCK MANDREL

The X Locking Mandrel operates in the same way as the R Locking Mandrel. The X Locking Mandrel is used in standard weight tubing. The R Locking Mandrel is used in heavy weight tubing.

XN PROFILE LOCK MANDREL

The XN Locking Mandrel is the “no-go” version of the usually selective locks. The keys have an angled shoulder on them instead of the square shoulder of the selective locks. A “no-go” shoulder of an equalizing sub or a crossover sub made up on the bottom of the lock must make contact with a bore restriction in the “no go” nipple, in order to lock this mandrel, can be used in conjunction with pump through plugs, poisitive plugs, safety valves, bottom hole chokes, and standing valves.

Other sizes, connections and material options available upon request.
