  • Publication number: 20060118293
    Abstract: A system for coupling a pipe segment to a pipe string is provided that includes a top drive assembly having an output shaft; and a pipe running tool coupled to the top drive assembly and rotatable by the output shaft of the top drive assembly. The pipe running tool includes an internal gripper for insertion within an internal diameter of the pipe segment and a tapered slip cone section, which slidably receives corresponding tapered surfaces of a plurality of slips, such that a vertical force on the slips causes the slips to move radially outwardly into gripping engagement with the internal diameter of the pipe segment, and wherein the vertical force applied to the slips is sufficient to allow the gripping engagement of the slips with the internal diameter of the pipe segment to transmit a torque from the top drive output shaft to the pipe segment.
