To the 25-th anniversary of Energodiagnostika Co. Ltd. (Moscow). History of foundation and development
Dr., Professor A.A. Dubov, General Director of Energodiagnostika Co. Ltd.
First the company named Energodiagnostika was founded under my initiative in November 1990 in Warsaw, Poland, and then in October 1993 in Sliven, Bulgaria. In Moscow a scientific-production union - SPU Energodiagnostika - was founded in November 1992.
The name of Energodiagnostika companies that were founded in 1990-1993 in Poland, Russia and Bulgaria has the meaning "diagnostics of power engineering equipment" because by that time I had already worked in this industry for about 30 years.
Further, approximately in 2005, due to realization of the physical bases of the metal magnetic memory (MMM) method as an energy state assessment method we got a new concept that reflect the company name "Energodiagnostika" - diagnostics of the inspection object’s energy state.
Thus, the very development of the MMM method in the company named Energodiagnostika led to formation of a principally new methodology - energy diagnostics (assessment of the energy store of equipment metal’s resistance to external loads)!
From the very beginning the basic activity of Energodiagnostika Co. Ltd. in Russia, Poland, Bulgaria, China and other countries was development of the new non-destructive testing (NDT) technology based on the use of the magnetic memory of metal. Solution of the following main tasks ensured the development of the MMM method and Energodiagnostika Co. Ltd.:
- Financial provision of Energodiagnostika Co. Ltd. activity.
- Development and manufacturing of principally new instruments-magnetometers for the MMM method.
- Development of regulatory documents on the MMM method and their standardization.
- Scientific and experimental substantiation of the new inspection technology based on the MMM method. The MMM method turned out to be principally new compared to the well-known magnetic NDT methods. Therefore I had to arrange a large complex of investigation works.
- Arrangement of training in the MMM method of Energodiagnostika employees and experts of other companies ordering our products.
- Advertisement and promotion the MMM method and new inspection instruments. Development and publishing of advertising booklets, papers, reference lists, participation in exhibitions, workshops and seminars, promotion trips to the customers’ enterprises.
- Holding of All-Russian and International Conferences on the topic "Equipment and Structures Diagnostics Using the MMM Method".
Earning of the money in order to solve the above-listed problems at the first stage (1991-1995) was realized due to execution of diagnostic works at electric power stations in Russia, Ukraine, Poland, Bulgaria and India.
At present we have offices in Moscow, Reutov, Ryazan and Beijing.
The head office, where the management, expert review and diagnostics department, financial and contract group and accounting department seat, is situated in Yubileiny Prospect Street in Reutov.
The Independent Body for personnel certification in the field of NDT (Certification Body), accredited by the Technical Supervision Body (Rostekhnadzor) in accordance with the established procedure, is situated in October Street in Reutov. The metrology laboratory and instrument repair and specialized scanning devices development and manufacturing department is situated in Stroitelei Street in Reutov. The department of development and manufacturing of specialized TSC (Testers of Stress Concentration) type inspection instruments is situated in Pushkin Street in Ryazan. We have our representatives in St.-Petersburg, Nizhny Novgorod and Kirov.
At present the number of full-time employees of Energodiagnostika Co. Ltd. (Moscow) is 35 people. The total number of experts working in Beijing and Sliven offices is about 40 people.
The scientific and technical potential of the experts working for the company and those engaged for solution of specific practical and scientific problems is at the highly professional level: from ordinary engineers to doctors of science certified to Levels II and III in non-destructive testing.
Energodiagnostika Co. Ltd. is a partner of the Russian Welding Society (RWS), is an active member of the Scientific-Industrial Union "Industrial Safety, Risks Management, Control and Monitoring" (SIU RISCOM). It is a founder of the self-regulating organization Non-Commercial Partnership "Interregional Association in the Field of Industrial Safety" (SRO NP "Mezhregion IS") and heads the subcommittee PK 1 "SSS Inspection and Lifetime" of Technical Committee TC 132 of Russian Federal Agency for Engineering Regulation and Metrology and the Work Group on the metal magnetic memory method in Rostechnadzor Expert Board and in International Institute of Welding.
During the last 25 years large work was performed in the field of development of regulatory-technical documentation on the MMM method as well as the work on standardization of this method. Physical bases of the MMM method were developed based on modern concepts of the materials science and fracture mechanics.
At present more than 60 guidance documents on the MMM method, approved by the Rostekhnadzor and branch institutes, are applied in practice in various industries of Russia. There are three national and international standards (ISO) on the MMM method.
The MMM method promotion to the international standard level was performed via the International Institute of Welding (IIW). It took about 14 years. In accordance with the International Program "Round-Robin" that was approved by the IIW the method was tested experimentally in laboratory and industrial conditions in six countries of the world (USA, Germany, Poland, Russia, China and India). During the period from 1994 till 2010 more than 40 IIW documents on the MMM method in various aspects of its development (theory, practical application, inspection instruments and techniques, training of experts) were published.
Nowadays, based on the international standards on the MMM method, national standards were put into effect in Russia, Ukraine, China, Poland, Mongolia, Iran, Portugal, United Kingdom, Canada and the Netherlands.
In 2010 the Technical Supervision Body included the MMM method in the list of basic magnetic methods admitted for application at hazardous industrial facilities. In accordance with the Resolution of the Chairman of Rostekhnadzor NDT Expert Council academician V.V. Klyuev a Work Group on the MMM method (headed by A.A. Dubov) was founded in 2010.
In 2011, as a result of an experimental testing of the MMM method’s efficiency in the laboratory and industrial conditions by TUV Rheinland experts, a Certificate for application of the method during pressure equipment and vessels examination and diagnostics was obtained.
As of June 2017, along with Russia, the MMM method and inspection instruments manufactured by Energodiagnostika Co. Ltd. became widespread in 40 countries of the world.
Energodiagnostika Co. Ltd. Certification Body performed training in the MMM method of:
- more than 2000 experts in Russia;
- more than 500 experts in China;
- 75 experts in Poland;
- more than 150 experts from other countries.
The Program of experts training and certification in the MMM method is approved by Rostekhnadzor. This Program and the Training Handbook were thoroughly examined by experts from different countries within the IIW Commission "Welding Quality Control" and adopted as an IIW document No. V-1347-06.
The work of the Certification Body on training of experts in the field of non-contact magnetometric diagnostics (NCMD) of pipelines based on the MMM method is of particular note. This unique NDT technology for state assessment of gas pipelines, heat lines, water pipelines located under a soil layer or under water at the depth of 2 or 3 meters and deeper at present becomes more and more widespread in Russian and other countries. As of the present time Energodiagnostika Co. Ltd. Certification Body, being the only center for NCMD training, as trained about 350 experts in Russia and other countries.
Summarizing the development of Energodiagnostika Co. Ltd. over the past 25 years, it is necessary to note once again the value of a new trend in technical diagnostics based on the use of the magnetic memory of metal to control the quality of engineering products during their fabrication and to assess the lifetime of operated equipment and structures.
It is known that the main sources of operational damage of equipment and structures are structural stress concentration zones (SCZ), in which the processes of corrosion, fatigue and creep develop most intensively.
Therefore equipment’s stress-strain state control using the MMM method for timely detection of SCZs is a most important task during assessment of equipment’s lifetime.
Welding exists in the world for more than 100 years, and the most important factor determining reliability of a welded joint - distribution of residual welding stresses - is so far not controlled due to the lack of NDT methods suitable for wide practical application.
The use of the magnetic memory of metal formed during the metal cooling after welding provides us with a unique possibility to simultaneously determine the RS distribution and to detect welding defects.
It happened so that while experts and diagnostic companies around us in Russia and abroad tried to understand our new NDT technology, and in many cases treated it with disdain, we purposefully and persistently developed the instrument hardware and specialized scanning devices. It is known that development of any technology depends, first of all, on instruments and devices that ensure its practical implementation. This is especially important for a "pioneer" technology, which is NDT based on the MMM method. Before appearance of the MMM method Russia and other countries had no multi-channel magnetometers, and even on the basis of modern electronic and computer equipment. Therefore now, after we spent more than 25 years for development of specialized instruments with integrated processor and program software to support the metal magnetic memory methodology and took the lead not only in Russia but also worldwide, we must not lose these achievements. As awareness of the MMM method’s advantages over other NDT methods grows, we will surely have competitors in manufacturing and distribution of inspection instruments in Russia and abroad.
And we already have such examples. About five companies appeared in China, who developed and start started manufacturing specialized instruments for the MMM method. Such companies appear also in Russia. In the coming years we should expect the appearance of manufacturers of specialized magnetometers in other countries as well. Therefore our task is not to stop and to continue our further development taking advantage of the methodology and, accordingly, of our developed algorithms and software products! We have to get ready to live and work in conditions of imminent competition.
In conclusion I would like to focus the experts’ attention on the most significant direction of our work on experimental and scientific investigations aimed at further development of the MMM method based NDT technology. This work cannot be interrupted. Cooperation of Energodiagnostika Co. Ltd. experts with branch and academic institutes and, most importantly, with industrial enterprises in Russia and other countries, which took place over 25 years, should be continued in future as well. We should constantly improve our work in all areas in order not to give ground in the development of the MMM method and to remain the parent company in this activity.
