Theoretical and Experimental Research on Designed Bursting Pressure of Ultrahigh Pressure Rupture Disk

Abstract

Rupture disk safety device plays an important role as the last safety barrier to prevent catastrophic overpressure in chemical vessels. In this article, a burst pressure calculation method of ultrahigh pressure rupture disk is presented based on “Levy–Mises Increment Theory” and “Torque Theory.” Besides, the calculation result is verified reasonable by numerical simulation and experiment. Thus, the calculation formula can be applied in the design of ultrahigh pressure rupture disk.
