Stress-strain state assessment capacitive apparatus taking into account impact piping for connectors

Abstract

Capacitive equipment in oil refining and petrochemical processes belongs to one of the most significant and responsible groups of process equipment of hazardous production facilities. Having various purposes, an impressive part of the process vessels is operated at increased pressures and temperatures under conditions of corrosion-erosion wear. Therefore, capacitive equipment must meet all the necessary requirements in the field of reliability and industrial safety. Depending on the effect of various operational loads and other factors, the distribution of the stress-strain state of the equipment elements can vary according to various scenarios depending on the determining parameter of the technical state and the dominant damage mechanism. One such factor may be the loads on the nozzles from process pipelines. The geometry features and various operational parameters of the piping can have a significant effect on the formation of the stress-strain state of the vessel and the distribution of areas of concentration of increased stresses. In the future, defects of various levels may occur in these zones. In this regard, the work on the study of the stress-strain state of the vessel is relevant, taking into account the loads that pipelines from the process piping exert on the nozzles.
