DTI 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 any CT operations where wired / fibre optic CT, or other BHA tools prevent the use of dropping balls. The robust Release Joint option can be used where high shock loads, vibrations, tensile force and/or torque forces are anticipated. The tool features a torque action through a sealed joint that can be released by applying pressure followed by a tensile load.
In a 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, it requires applying a predetermined pressure, which shears the pins and releases the latch collar. An overpull action then shears the overpull release pins to separate the released joint and leave an internal fish neck which can be latched with a standard DTI GS Pulling Tool, if required.
The DTI Flow Pressure Release Joint is available in standard and H2S service versions, please contact your DTI representative for more information.
