Evaluation of the possibility of using thermal method for leakage testing of the boilerof a railroad tank car

The article presents the results of experimental studies to assess the possibility of using thermal methods of controlling the leakage of the boiler of a railroad tank car. This paper reflects the research of formation of the thermal field on the outer surface of the tank in the area of end-to-end defect such as a crack, by throttling through the gas medium due to the pressure differential. Presented thermograms show the localization of the defect with a detailed description of the anomalies of the thermal fields, recorded by the imager. Also confirmed the experiments described in the work on Joule and Thomson for throttling gas through local obstacle.
