  • Local electrochemical impedance spectroscopy (LEIS) for detecting coating defects in buried pipelines
    Patent number: 8310243
    Abstract: A system and associated methods for acquiring and analyzing LEIS data from a buried structure, such as a pipeline. A special probe having adjustable electrodes is placed in the soil above the structure. A voltage is applied to the structure, causing more current to emanate from a coating defect than from intact coating. The probe electrodes acquire a response signal, which is analyzed to detect the defect.
    Type: Grant
    Filed: August 10, 2010
    Date of Patent: November 13, 2012
    Assignee: Southwest Research Institute
    Inventors: Pavan K. Shukla, Todd S. Mintz, Biswajit Dasgupta, Jay L. Fisher, Osvaldo Pensado-Rodriguez
