APPLICATION EXPERIENCE OF NON-CONTACT MAGNETOMETRIC DIAGNOSTICS OF PIPELINES AND PERSPECTIVES OF ITS DEVELOPMENT
(pp. 21-24)

Abstract. At present practical application of non-contact magnetometric diagnostics (NCMD) during the assessment of underground or underwater gas and oil pipelines, heat lines, water mains and other pipelines constantly grows. The article considers the main problems revealed by the authors as a result of the longterm application of NCMD, the issues of experts training at Energodiagnostika Co. Ltd. Certification Body and the perspectives of NCMD technology development.

Keywords: gas and oil pipeline, ground ripping-up, heat line, metal magnetic memory, non-contact magnetometric diagnostics, nondestructive testing, pipeline, stress-strain state.
