The Research of the Stress-Strain State of the Pipeline System, Taking into Account the Change in Spatial Location

Abstract

In the work, the influence of changes in the geometry of the technological pipeline on the stress-strain state is studied, taking into account the complexity of the strapping of technological equipment and the parameters affecting the deformation. The authors analysed the stress-strain state of technological pipeline systems with a change in their spatial location, simulated 3 options for the spatial location of the pipeline system. The best option was selected to ensure its reliable operation, depending on the design parameters. In conclusion, the effect of hydraulic load on the VAT of the pipeline was investigated. The calculations were carried out according to the standard method in the PC program “Start” and using the finite element method in the PC SolidWorks. It is established that a change in the geometry of the pipeline system significantly affects its stress-strain state. On the example of changing the geometric arrangement of equipment piping shown the possibility of reducing VAT in the pipe bends by 19%. It is shown that when assessing the strength of technological pipelines with complex geometry and a significant number of elements, it is necessary to take into account hydraulic loads, which can increase the VAT in pipeline elements up to 21.7%.

Stress in the tank case at mounting displacements and loads on nozzles

“…For example, a complex effect on the SSS in the housings of capacitive equipment can have a combination of factors such as the tapping of new nozzles, changes in operating parameters, as well as the displacement of the edges of the joined elements in annular welds. With their complex impact, the formation of SPD in the vessel housings may be rather ambiguous, which must be taken into account when assigning a further service life and ensuring operational reliability [9][10].…”
