Learn more about PASS/START-PROF pipe stress analysis software
Flange leak resistance analysis follows GOST 32388-2013 (Appendix B). In addition to pressure loads, flanges experience axial forces and bending moments determined from piping stress analysis (using tools like Start-Base). These mechanical loads are included in the flange pressure rating calculation.
