A spinner apparatus for installing a pipe segment into a well pipe having a frame with a reach area formed therein, a first arm pivotally connected to the frame, a first roller rotatably mounted on the first arm, a second arm pivotally connected to the frame, a second roller rotatably mounted on the second arm, a third arm pivotally connected to the frame, a third roller rotatably mounted on the third arm, and an actuator linked to at least one of the arms so as to pivot one of the arms such that the respective rollers on the arms move into the reach area. Each of the arms is linked together such that a movement of one of the arms causes a concomitant movement of another arm so as to position the rollers around an outer surface of the pipe segment such that the pipe segment will have a central longitudinal axis in an identical position regardless of the diameter of the pipe segment.
