  • 5 Round Mandrel Slip Joint - China

    price: contact company for price

    Halliburton type, could change with Halliburton parts. Accepts the

    movement associated with ocean heave or temperature change

    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 has the following characteristics:

    • Top of the mandrel slip joint has

    4 3/4-in. (120.65-mm) drill collar profile for easy handling with

    the rig elevators and slips

    • Maintains its full tensile rating when collapsed and locked

    • Can be locked in the closed position for handling, reducing

    the risk of damage to the lifting/sealing mandrel

    • Internally pressure and volume balanced

    • String can be picked up with the slip joint locked; the slip joint can then be unlocked before it is run into
    the hole

    • Provides free travel in the string to

    reciprocate tools without unseating the packerA slip joint

    operates by balancing its volume. As the slip joint stretches and increases its internal volume, adifferential
    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.
