Read about START-PROF pipe stress analysis software
Flange leak resistance is calculated based on GOST 32388-2013 (appendix B). In addition to external and internal pressure, flanges are affected by axial force and bending moment, the values of which are determined by the analysis of the overall stress-deformed piping (for example, using Start-Base). These values are considered in pressure analysis for flange selection.
