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. The Round mandrel slip joint can also be used in overland formation testing operation that compensates pipe string elongation and contraction due to temperature and pressure changes. The slip joint can also connected to the lower end of multi-flow testing valve and provide free travel for testing valves switch.
