The Brace Tool XN No-Go Landing Nipple is designed for use in single nipple installations or as the bottom nipple in a series of Brace X Landing Nipples. These Landing Nipples have the same packing bore ID for the particular tubing size and weight. Brace XN Landing Nipples are designed for use with standard weight tubing.
The completion typically contains only one XN type no-go landing nipple. These are placed at the bottom of the production string. The Brace XN lock mandrel is run through the tubing string with a X type running tool in the non-selective position.
