The main results of research and development in the field of creating technologies for the thermal control method carried out at the Research and Technical Center «Thermocontrol» of the Kharkiv National University of Radioelectronics since 1973 and up to the now, are presented. The results of application of thermal technologies for diagnosing bearing wear and electrical insulation faults in submersible electric motors of the SEM series used for oil production are shown. The results of monitoring the condition of metal in pipelines of the NPP unit rooms are given. It turned out that the defects caused by cavitation erosion have a “heat trace” and can be registered by the thermal method. The technology for diagnosing underground pipelines and leaks in them is described. A method of statistical processing of the results of thermal diagnostics of gas-pumping units of main gas pipelines has been developed, which includes creation of a virtual reference sample of the selected part of the unit; informative features for comparing temperature fields were formed; a decision rule was formulated, which indicates the deviation of the selected informative features from the reference value. The results of calculating the level of the liquid phase in gas pipelines have been experimentally confirmed. The results of a thermographic survey of the hydrotechnical structures of the Dnieper HPP are presented. The quantitative indicators of heat losses of buildings during thermal imaging inspection are given. The directions and prospects of the development of the thermal method are considered. Ref. 20, Fig.9 Key words: thermal non-destructive testing, thermal diagnostics, submersible motors, underground pipelines, cavitation erosion, hydraulic structures, heat losses
