Flexible device for remote field eddy current inspection of ferrous pipeline containing turns

摘要

A device is taught for inspecting the integrity of water distribution pipelines. The device is constructed of housing units, for housing inspection circuitry. The housing units are connected by flexible connectors which permit the units to move out of axial alignment to pass bends. In some embodiments, communication ports are provided 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.
