"S" / "T" Locator

Description

The Type “S” and “T” Locator Mandrels are made up to the bottom of the “S” and “T” Locking Mandrels to set in Type “S” and “T” Landing Nipples. It is the position number of the keys on the locator mandrel that allow the locking mandrel to be termed selective. By changing the keys from one position to another, you may set the locking mandrel in one of five different nipples in the tubing string. The spring loaded position keys “seek out” and locate the corresponding position nipple and prevent the lock from traveling out of the bottom of that nipple. Once this is accomplished, the locking mandrel would hold pressure from below while the locator mandrel would hold pressure from above.
