  • CAAP A Novel Structured Light Based Sensing and Probabilistic Diagnostic Technique for Pipe Internal Corrosion Detection and Localization
    CAAP: A Novel Structured Light Based Sensing and Probabilistic Diagnostic Technique for Pipe Internal Corrosion Detection and Localization
    Alzuhiri, Mohand ;
    Rathnakumar, Rahul
    2021-04-01 | PDF
    Internal corrosion in pipes is dangerous due to multiple factors contributing to its development. Degradation of the pipeline health is susceptible to hazard due to failure. To prevent such failures, a major challenge for the maintenance crew to detect and repair corrosion still prevails due to difficult and expensive accessibility during scheduled ...
  • Electromagnetic Strategies for Locatable Plastic Pipe

    External Leak Detection Body of Knowledge
    Stuver, Susan ;
    Moore, Chris
    2021-01-29 | PDF
    This work will develop a recommended practice (RP) for external based leak detection on natural gas transmission lines. Through extensive interaction with utilities, vendors, and the technical advisory panel, GTI will combine existing data into a current RP that can be adapted to new technologies and methodologies. The developed RP will build on ex ...

    Corrosion of underground natural gas and liquid petroleum pipelines occurs by a variety of forms and requires specialized methods to detect and control. Stress corrosion cracking (SCC) is a form of corrosion that results in clusters or colonies of cracks on the surface of the affected pipelines. While the three conditions necessary for SCC (metal s ...
