Identification of zone of increased stresses of the apparatus with a shirt under conditions of corrosion wear by modeling

Abstract

Abstract Apparatuses with a shirt have two working cavities with independent pressures and temperatures, as well as independent working environments. When operating two cavities, a certain difference in pressure and temperature is simultaneously created, leading to the appearance of unfavorable zones, which can negatively affect the life of the apparatus. For the timely identification of the most unfavorable zones, a wide range of non-destructive testing methods are used, which make it possible to assess the actual technical condition and level of metal defectiveness. However, due to the design features of the apparatus with the shirt, it is quite difficult to conduct a full visual control of the inner surface. Therefore, the actual work is to assess the stress-deformed state of equipment with an original design using modeling in modern software systems in order to identify potentially dangerous sections in terms of maximum operating stresses.
