OSTI ID:538819
There is a recognized need for an advanced distribution pipe inspection system which can operate in 4` and 6` diameter pipes. This program developed a prototype sensor car based on vector magnetometry. The prototype sensor system was tested in the laboratory. Test data is presented showing defect detection capability for defects as small as 25% of the pipe wall. Field tests were also conducted with mixed results. Varying corrosion levels were observed. However, specific defects were difficult to identify.
