Complex method of railway tanks and reservoirs tightness control

This article presents the development of a complex method of tank impermeability control by the example of rail tank cars. Application of methods of acoustic emission and thermal control makes it possible to detect defects on the surface of tanks in two stages-localization of the through defect is carried out by the acoustic method, and the determination of geometrical size of the defect by the analysis of temperature anomalies of the outer surface of the tank. Application of such method in practice increases reliability of nondestructive control of railway tanks and reservoirs. (paper)
