Abstract
A modular pipe gripping assembly has a universal actuator assembly having a control fluid swivel. An external pipe gripping assembly can be attached to the actuator assembly for gripping the external surface of a section of pipe. Alternatively, the external pipe gripping assembly can be quickly and easily removed and replaced with an internal pipe gripping assembly for gripping the internal surface of a section of pipe. Control fluid pressure is trapped within the actuator assembly, but relieved from a fluid swivel, permitting high speed rotation of the modular pipe gripping assembly and preserving swivel seal life.
