dc.description.abstract	A thermophysical model of a pipe with a local defect of the “wall thinning” type is developed. Calculations of thermal anomalies for pipelines with different parameters of hidden defects are performed, illustrating the possibility of using the thermal method of nondestructive testing. The conditions and methods of thermal control of individual sections of pipelines are specified. Thermal imaging examination of steam pipelines of the main condensate of the nuclear power plant was carried out. External factors that make it difficult to detect hidden defects (the influence of external lighting, cylindrical shape of controlled objects, powerful external heat sources) are analyzed. It was found that cavitation phenomena significantly increase the temperature drop in the locations of local defects. The possibility of using the thermal method of nondestructive testing for rapid detection of hidden defects such as “wall thinning” in the pipelines of the main condensate has been confirmed experimentally.	uk_UA
