  • Tapping point clearing apparatus
    Patent number: 9468955
    Abstract: A process tapping point clearing apparatus (10) has a ram housing a piston (25) in a cylinder (12). A piston shaft (22) has a threaded first end (30) threadingly engaged with the piston. A second end of the shaft retains a clearing head extending from the cylinder, the clearing head adapted to pass through a process tapping point for removing scaling and/or debris material therefrom. The threaded first end of the shaft has an outer thread (36) diameter substantially the same as the diameter of the adjacent intermediate portion of the shaft. The piston can have a threaded aperture (44) to receive an release tool (45) to retract the piston and tapping point clearing toll (34) if stuck in an extended position.
