Abstract
A tool, system and methods for plugging broken fluid delivery pipe are disclosed. A plugging tool can be used to plug a fluid leak in a broken pipe. A relief pipe and associated relief valve assembly can be installed on the sides of the broken pipe. Before plugging, the relief valves can be opened to relieve back pressure created during plugging operation. The relief piping can be installed on the side of a broken pipe using a diamond blade edging technique followed by threading. The tapered portion of the tool facilitates the plugging process and snuggly fit the tool into the broken pipe. A fluid storage mechanism can be provided for storing fluid obtained from the plugged pipe via relief pipes under the control of associated relief valves.
Claims5
A system for plugging a broken pipe delivering a fluid at high pressure, comprising:
- a plugging tool including a threaded shank member threadably movable within a tapered shaft, said tapered shaft insertable within a end of a broken pipe under fluid pressure and retained within the broken pipe at the end of a broken pipe by a plurality of jaw members pivotably supported within the tapered shaft of the plugging tool and firmly deployed against a inner surface of the broken pipe;
- at least one relief pipe including a valve assembly installed on a side of the broken pipe;
- and
- fluid storage coupled to the relief pipe for storing fluid obtained from the broken pipe once the broken pipe is plugged by the plugging tool.
A method of plugging a broken pipe that is under fluid pressure, comprising:
- inserting a plugging tool including a head end and tapered shaft into an opening of the broken pipe;
- turning a handle integrated with a threaded shank member threadably integrated within the tapered shaft of the plugging tool to deploy a plurality of jaw members pivotably supported within the tapered shaft against an inner surface of the broken pipe;
- wherein the threaded shank is moved within the tapered shaft by turning the handle until the plugging tool is tightly secured within the broken pipe and against the inner surface of the broken pipe by the plurality of jaw members.
A method of plugging a broken pipe that is under fluid pressure, comprising:
- installing at least one relief pipe on a side of the broken pipe prior to plugging the broken pipe with a plugging tool;
- connecting the at least one relief pipe to a fluid storage system;
- open a relief valve associated with the at least one relief pipe prior to plugging the broken pipe to relieve back pressure created during plugging of the broken pipe;
- plug the broken pipe with a plugging tool including a head end, a tapered shaft, a handle integrated with a threaded shank member threadably integrated within the tapered shaft and a plurality of jaw members pivotably supported within the tapered shaft, where the plugging tool is secured within the broken pipe by turning the handle integrated with the threaded shank member that is threadably integrated within the tapered shaft of the plugging tool to deploy the plurality of jaw members pivotably supported within the tapered shaft against an inner surface of the broken pipe;
- and
- collecting fluid from the broken pipe that is plugged by the plugging tool.
