The round mandrel slip joint is the part of the drill stem testing work string.

3 7/8" Round Mandrel Slip Joint in Stock
The round mandrel slip joint, like other slip joints, accepts the movement associated with ocean heave or temperature change without allowing the movement to disturb the placement of downhole tools.
A slip joint operates by balancing its volume. As the slip joint stretches and increases its internal volume, a differential piston within the slip joint allows the same volume of fluid into the pipe. The net result is no change in internal volume.
Each slip joint has 5 ft (1.52 m) of travel but can be combined with other slip joints to provide additional travel.
When multiple slip joints are run, they are normally connected to one another rather than located throughout the pipe string. The number of slip joints required depends on ocean heave and the amount of expected contraction and expansion.
Features and Benefits
• Provides a variable-length joint to allow the pipe to expand and contract during testing or stimulation
• Keeps vertical movement of the drilling vessel from disturbing tool placement
• Helps space out the testing string when the subsea tree is landed
• Provides a constant weight on the packer during testing or stimulation
