The Conference "Diagnostics of Equipment and Structures Using the Metal Magnetic Memory" was held on February 25, 2021, in Moscow. It was initiated by Energodiagnostika Co. Ltd. The conference organization was supported by: the Russian Welding Society (RWS), the Scientific and Industrial Union “Risk Management, Industrial Safety, Control and Monitoring” (SIU RISCOM), the TC 132 Technical Committee of the Federal Agency for Technical Regulation and Metrology of the Russian Federation, the Hungarian Association for Non-destructive Testing “MAROVISZ”, the Czech Society for NDT and the European Federation for NDT (EFNDT).

More than 170 specialists from different cities of Russia and other countries officially applied for participation in the conference: Argentina, Belarus, Brazil, Bulgaria, China, Czech Republic, Hungary, Iran, Japan, Kazakhstan, Korea, Lithuania, Malaysia, Moldova, Poland, Saudi Arabia, UAE and Ukraine.

Reports on the following topics were presented at the conference:

  • Application of the metal magnetic memory (MMM) method and totals of its development in Russia and other countries (as of January 2021, the MMM method has come into common use in 45 countries throughout the world).
  • Quality control of engineering products by structural inhomogeneity and residual stresses.
  • Control of equipment and structures' actual stress-strain state – the main direction in the technical diagnostics development.
  • Modern instruments and scanning devices for diagnostics of technical devices by the MMM method.
  • Non-contact magnetometric diagnostics (NCMD) underground pipeline sections and external pipelines through the insulation layer.
  • Personnel training and certification in the MMM method at Energodiagnostika Co. Ltd. Certification Body.
  • Report on the work of the ICNDT Specialist International Group on the MMM method for the period of 2018 – 2020.

The main attention was paid to the practical experience of the MMM method application in various industries and at various facilities. In particular, reports were presented on current problems of non-destructive testing and lifetime assessment of engineering products, equipment and structures and ways of their solution based on application of the metal magnetic memory method; on the prospects of the MMM method and inspection instruments development and spreading in Russia and other countries. Reports on determination of mechanical properties and the level of stress concentration in local zones of products detected by the MMM method; on the experience of the MMM method application in the oil and gas industry, power engineering, oil refining and other industries were presented. Separate reports were made on non-contact magnetometric diagnostics of pipelines located under the soil layer and under water.

More than 17 reports including 8 reports by foreign experts were presented in total.

Special attention was drawn to the report by Al. Dubov on non-contact magnetometric diagnostics, in which a unique program for processing NCMD data was presented based on calculation of the slip angle limiting value, at which damage begins to develop in the pipeline metal. The program has been tested during processing of NCMD data for pipelines used for various process purposes.

The report by A. Dubov "Modern instruments and scanning devices for technical diagnostics by the MMM method" presented some new developments:

  • the magnetic eddy current complex (MEC-TSC) capable to operate both in the eddy current control mode and in the mode of the MMM method;
  • a scanning device for in-line diagnostics of the stress-strain state of gas and oil pipelines, which has no analogues in Russia and throughout the world.

The report by S. Kolokolnikov "Specialists training and certification in the MMM method at Energodiagnostika Co. Ltd. Certification Body" notes that as of January 2021 more than 3500 experts, including over 800 foreign specialists, were trained and certified.

P. Ladanyi (Hungary) presented a report on the work of the ICNDT Specialist International Group on the MMM method for the period of 2018 – 2020. Significant work was carried out at the International Institute of Welding (IIW) to revise and agree the new revision of the international standard ISO 24497 on the MMM method. Specialists from Russia, Germany, Hungary, Canada, Czech Republic, Poland took an active part in this work. ISO/TC 44 held a successful vote on the new revision of ISO 24497 standard in March 2020.

The report by E. Gorokhov (IGP SRL, Buenos Aires, Argentina) contained an overview of the world's existing inspection devices used in non-contact magnetometric diagnostics of underground pipelines. It was noted that the Pipeline Research Committee International (PRCI) included the metal magnetic memory method, developed by Energodiagnostika Co. Ltd. (Russia), in the list of LSM methods designed to assess the stress-strain state of underground pipelines of any purpose. LSM is a family of remote test methods for classifying anomalies based on risk category.

The general opinion of participants was the need for further practical implementation of the MMM method as an effective method of early metal and welded joints diagnostics of vessels, pipelines and other equipment for various industrial applications, continuation of theoretical and experimental studies to improve the method and control criteria. The conference participants made a proposal to include the MMM method in the list of NDT methods, based on which specialists are certified in accordance with the international standard ISO 9712, and the ICNDT Specialist International Group was invited to take an active part in the work of the European conference on NDT and condition monitoring “ENDT&CM 2021” (Czech Republic, 2021) and the world NDT conference (Korea, 2022).
