ABSTRACT:
A device is taught for inspecting the integrity of water distribution pipelines. The device is constructed of housing units, for housing inspection circuitry, which are generally spherical in shape. The housing units are connected by flexible connectors which can, in some embodiments, allow for communication between the units. As such, the device is able to negotiate bends and pass through openings of reduced size in the pipeline. The device can be used with various inspection technologies including remote field eddy current inspection technology. A method for inspecting the integrity of a water pipeline system is disclosed wherein water hydrants can be used to access the system.
