Thrust force in Modeling Relief Valve (Pressure Safety Valve)

START-PROF software provides comprehensive pipe stress, flexibility, stability, and fatigue strength analysis with related sizing calculations according to international and national codes and standards. Start-Prof can evaluate the support loads and stresses caused by relief valve discharge by static method. The relief valve discharge thrust load acts on elbow 28. In Start-Prof it should be applied at the end of the elbow in 29 node.

Methods for estimation:

1.ASME B31.1 method







2.Direct calculation of V1 и P1 by special software like Hydrosystem
