A device is taught for gripping casing joints comprising one or more first cylinders and one or more second cylinders actuated by a singular hydraulic system. A second device is taught comprising a gripping system, said gripping system comprising one or more slips cammed against one or more inclined recesses when the gripping system is rotated to maintain gripping engagement of the casing. A third device is taught comprising a gripping system, said gripping system comprising one or more slips received into one or more inclined recesses. A fourth device is taught comprising one or more dies supported on one or more said slips by means of mating load transfer profiles. A fifth device is taught comprising a tubular guide means. A sixth device is taught comprising an integral fluid compensator chamber. A seventh device is taught comprising a hydraulic swivel comprising one or more sealing means having predictable seal fluid leak rates.
A device for gripping casing joints for making up or breaking out casing strings comprising one or more hydraulic cylinders comprising:
A device for gripping casing joints for making up or breaking out casing strings comprising a gripping system, said gripping system comprising one or more slips cammed against one or more inclined recesses when the gripping system is rotated to enhance gripping engagement of the casing.
A device for gripping casing joints for making up or breaking out casing strings comprising a gripping system, said gripping system comprising one or more slips received into one or more inclined recesses.
A device for gripping casing joints for making up or breaking out casing strings, said device comprising one or more dies supported on one or more slips by means of mating axial load transfer profiles formed on said slips and on each of said dies.
A device for gripping casing joints for making up or breaking out casing strings, said device comprising a tubular guide extending from a lower end of the device to receive and center the casing joint into a central bore of the device.
A device for making up or breaking out casing strings comprising an integral fluid compensator chamber.
A device for making up or breaking out casing strings comprising a hydraulic swivel to house fluids for hydraulic actuation of the device, wherein said hydraulic swivel comprises one or more sealing means having predictable and controllable seal fluid leak rates.
