The Micro-Magnetic Casing Crawler (MCC) is a remotely controlled robotic inspection tool capable of inspecting and collecting data from within the annular space of cased pipe. Federal pipeline integrity rules require cased pipeline operators evaluate their pipeline on a regular basis. Since much of this pipeline is buried under highways, railroad tracks and even airport runways, the pipeline is very difficult to access without the possibility of disruption to the public. It was developed to provide a remote inspection of cased pipeline. The ultra-compact crawler magnetically attaches to the inside of the casing pipe and is small enough to travel past the spacers, accessing several hundred feet of cased pipeline from just one point of access.
