Evaluation of the stressed-deformed state of the apparatus taking into account the influence of adjacent equipment and its geometric deviations

Abstract

For timely field monitoring of equipment, the widest arsenal of non-destructive testing methods is used, which with a sufficient degree of reliability allows determining the degree and admissibility of defects in accordance with established standards. The required list of works and the established values are established by regulatory documents on industrial safety and technical diagnostics. As a rule, each device is subjected to a technical inspection individually with an individual set of tools to predict the residual life of a safe service. Existing methods do not take into account the possible impact on the surveyed apparatus of the loads and effects exerted by operational environment devices of the tested device. In addition, the current regulatory and technical documentation does not take into account the mutual influence of the quality of installation or repair of interconnected equipment. Various geometric deviations appearing during installation, repair, or operation, such as, for example, deviations from verticality, can serve to redistribute the stress-strain state and lead to premature failures and decommissioning. In this paper, we study the relationship between the impact of equipment in a technological connection on the operational parameters, as well as that of the geometric deviations of adjacent equipment on the stress-strain state of the apparatus.
