Round Mandrel Slip Joint:
Round Mandrel Slip Joint is mainly used in FUL-FLO formation test, hook wall test, fracturing, acidizing operations in drilling pontoon. On this account, the center shaft expansion joint could compensate floating up and down in drilling pontoon and guarantee to set-down right amount of gravity in downhole tool. This joint can also be used in overland formation testing operation. It compensates pipe string elongation and contraction due to temperature and pressure changes. The joint can also connected to the lower end of multi-flow testing valve and provide free travel for testing valves switch.
