Application Experience of Non-Contact Magnetometric Diagnostics of Pipelines and Perspectives of its Development

摘要

At present practical application of non-contact magnetometric diagnostics during the assessment of underground or underwater gas and oil pipelines, heat lines, water mains and other pipelines constantly grows. The criteria and the program software, developed at Energodiagnostika Co. Ltd. based on the metal magnetic memory method, are applied for decoding of the information about the pipelines condition by variations of the magnetic field of the earth recorded at the depth of 200 to 300 mm from the earth surface. The report considers the main problems revealed by the authors as a result of the long-term application of non-contact magnetometric diagnostics, the issues of experts training at Energodiagnostika Co. Ltd. Certification Body and the perspectives of non-contact magnetometric diagnostics technology development.
