Abstract:
Analysis of industries, where passive thermal imaging methods of control became accepted for diagnostics of technical condition of difficult-of-access and potentially hazardous industrial facilities, was performed. Service conditions of the most common potentially hazardous industrial flue pipes were considered. The causes for formation and main types of defects and damage in structural elements of flue pipes were analyzed.  The main methods for assessment of technical condition of flue pipes by passive thermal imaging method are presented, that is performed by solving the direct flaw detection problem using models of thermograms of anomalies in temperature fields on the flue pipe outer surface. Ref. 10, Table. 1, Fig. 6. 45
Key words: flue pipe, passive thermal imaging method of control, causes for formation of discontinuities, methods of assessment of the technical condition
