A complex of studies has been performed to establish the causes for damage of a platelike heat exchanger from AISI 316L stainless steel. Analysis of service conditions, methods of optical, scanning microscopy, visual examination, massometry, physical methods of media analysis, and testing for local corrosion resistance were used to establish the causes for formation of through-thickness damage of heat exchanger plates. It was proved that initiation of through-thickness defects is due to complex interaction of a set of factors, namely: breaking up of passive film in the points of plate abutment, development of intercrystalline corrosion of the surface layer at long downtime of a heat exchanger with a disinfectant preservative liquid, leading to formation of stagnant zones between the corrugations of the plates pressed to one another, where the liquid was retained, and increase of water corrosiveness relative to steel. 22 Ref., 4 Tabl., 5 Fig.
