Flow Pressure Release Joint

Disconnect without dropping a ball using the DTI Flow Pressure Release Joint.
 
The DTI Flow Pressure Release Joint is designed for CT operations where wired / fibre optic CT, or other BHA tools prevent the use of drop balls. The robust Release Joint can be used where high shock loads, vibrations, tensile force and / or torque forces are expected. The tool features a torque through sealed joint that can be released by applying pressure followed by tensile load.

In normal operation, the latch mechanism is locked in place by a collar which is held in position by calibrated shock load protected shear pins. To release the joint, applying a predetermined pressure shears the pins and releases the latch collar. An overpull then shears the overpull release pins to separate the release joint and leave an internal fish neck which can be latched with a standard DTI GS Pulling Tool.

The DTI Flow Pressure Release Joint is available in standard and H2S service versions, please contact your DTI representative for more information.
