ABSTRACT:
A retractor tool adapted to insert and retrieve sensing, measuring or control devices in high pressure containers, such as a pipeline, through an access valve and stuffing box without interrupting the fluid flow within the vessel or relieving the pressure. The tool is connected to the stuffing box by a clamshell clamp which utilizes the threaded rod of the apparatus at its hinge axis. The measuring device is inserted or retracted by the operation of a thrust coupling on the retractor threaded rod. Translational movement is imparted to the thrust coupling by means of a handle nut. The retractor tool can be attached to both hex stuffing boxes and cylindrical stuffing boxes.
