During the manufacture, transportation, installation, repair or operation of technological apparatuses of hazardous production facilities, a gradual accumulation of damages of various levels inevitably occurs. This damage can be of a technological, mechanical or operational nature. Subsequently, under certain operational factors, they can have a negative impact on the operational reliability and industrial safety of the apparatus, being potentially dangerous areas of premature destruction. The most common damage mechanism is various types of corrosive wear, which bring a construction closer to a loss of strength due to a decrease in the wall thickness of constructional elements. As a rule, corrosive wear also affects the stress-deformed state, increasing the maximum effective stresses in these zones. Almost always, there are mechanical damages on the devices - scratches, of various sizes, lengths and locations. Scratches can form at all stages of the apparatus's life cycle, from manufacturing to the transition of the apparatus to the limiting state. The permissible size of damage is strictly regulated by the current regulatory and technical documentation in the field of industrial safety. But, in conditions of corrosive wear, with the thinning of the walls of the apparatus elements, a scratch with permissible dimensions can have a significant, and sometimes decisive effect on the stress-deformed state of the apparatus. Currently, the assessment of the stress-deformed state in modern software systems, considering various factors, is relevant and in demand. This paper investigates the relationship between the size and location of the scratch in the area of uniform corrosive wear of the shirt's body, various values of thinning, as well as the action of operational loads.
