ABSTRACT

The simulation results of the stress-strain state using the software ANSYS area pipe connection to the steam boiler high pressure drum for pipe connections of various diameters and wall thickness. The areas of extreme local stresses and values of strains caused by the pressure inside the drum and the pipe connection and the temperature gradient in their walls have been determined, stress concentration factors have been calculated. A comparison of the calculated stresses with the stresses obtained by the strain measurement of a physical model of the drum with welded pipe connections has been made. Functions of the extreme stress changes depending on the position of the diametrical section of the pipe connection has been determined. Using the obtained values of stress and concentration coefficients allow to specify the strength calculation of the high-pressure drum and their reliance on low-cycle fatigue
