  • End prep tool and tool centering and mounting system for use therewith
    Patent number: 6994002
    Abstract: An end prep tool is mounted in substantial alignment with a theoretical center of a pipe and used to prepare an end of a pipe, for example, by boring and/or cutting the end of the pipe. A tool centering and mounting system comprises a clamp cage and a tool mounting member having an inner cylindrical surface. A centering tool is mounted to the tool mounting member and used to adjust the tool mounting member until substantially aligned with the theoretical center of the pipe. The end prep tool comprises a tool feed assembly that moves a cutting tool radially with respect to the axis of rotation and axially according to a predefined cutting profile.

  • Clamp release mechanism for an end finishing tool
    Patent number: 5531550
    Abstract: An end finishing tool includes a mandrel with a plurality of ribs at its distal end; an actuator longitudinally moveable in a first direction relative to the mandrel for moving the ribs radially outwardly in the installation mode to grip the inner surface of a conduit to be finished and in a second opposite direction for enabling the ribs to move radially inwardly in the extraction mode; an actuator driver threadably engaged with the actuator for driving the actuator in the first and second directions and a clamp release device for arresting movement of the actuator driver in the extraction mode for compelling the actuator to move in the second direction for enabling the ribs to move radially inwardly and release the inner surface of the conduit.
