Brief introduction of Full bore safety joint


To initiate the release of the safety joint, a tension sleeve must be parted by pulling on the workstring. For complete release, vertical and rotational movement must be applied.

The RTTS Safety Joint should be run on all special tool and DST jobs directly above the packer.  The purpose of the safety joint is to provide a disconnect point in the tool string above the packer for removal of all equipment above that point if the work string becomes stuck and the Safety Joint can still be operated.

The RTTS safety joint can be installed on the top of RTTS circulating vale as well as between the RTTS circulating valve and RTTS packer. The RTTS Safety Joint is held inoperative by a tension sleeve located on the bottom of the mandrel to help prevent premature release.
