ABSTRACT:
A tool for removal of debris from within a transmission pipe containing gas under pressure, including, a slide tube, having an angled fitting provided at its bottom end, and generally for disposition within the transmission pipe, said slide tube extending through a reducer, that incorporates and includes therein a mounting member, such as a swivel ball, through which the slide tube locates, and has a hermetic seal therewith. The slide tube 2 at its upper end includes one or more shut-off valves, and may also incorporate a filter device, for collecting of the accumulated debris that is carried with the pressurized gas as it rapidly passes through the slide tube, after opening one or both of the shut-off valves. The slide tube generally mounts within the reducer, with the application of a pair of fittings, that cooperate with valve seats, for compressing against the swivel ball, to prevent the by-passing of any pressurized gas therepast, when the various shut-off valves are opened, for discharge of gas entrained debris, or even when the shut-off valves are closed, to prevent any further passage of the pressurized gas from the transmission pipe in which the pressurized gas is conveyed.
