The burst tolerance is always В±5% in accordance with all the rupture disk codes for stamped burst pressure equal to or greater than 40 PSIG (275.8 kPag) @ 22 ВєC. The burst tolerance varies, according to the particular disk design for stamped burst pressures below 40 PSIG @ 22 ВєC. rupture disk is a non-reclosing pressure relief device actuated by the differential pressure between the inlet and outlet sides of the disk, and it is designed to function by bursting.

phase relief-device design is more difficult than single-phase design (2, 4); experts with specialized knowledge should perform two-phase relief design. This article discusses only the sizing of relief devices for single-phase flow — either all gas or all liquid entering the relief device. Although relief devices may never be activated, they must be designed and sized to function correctly Specification variables to consider when choosing the correct disc include required burst pressure, burst temperature, whether the application is one phase or two phase, whether it must be a non-fragmenting design, and whether the disc has to withstand

Detailed pressure relief system on the reactor is presented in Figure 3 and is composed of safety relief valve (SVR) and rupture disc (RD) with dimensions presented in Table 1. The pressure at which SVR piston opens depends on the physicochemical characteristics of reaction system. In present study, it is designed so that SVR opens when the reaction medium pressure is above 70 В· 10 Rupture discs are non-reclosing pressure relief devices which open within milliseconds when system pressure reaches its specific burst rating. They are designed to relieve either positive or negative conditions at a specified set pressure and in some applications, additionally withstand vacuum or backpressure. Rupture discs may also be designed to provide dual relief (positive or negative

Design of rupture discs. Rupture discs for pressure relief are round or square, consist of one or more layers, and are either flat or domed. Many rupture discs are equipped with breaking points which are created for example, by means of lasers. A rupture disk device is a non-reclosing pressure relief device that actuates upon differential pressure across the disk. It consists of two main components: the rupture disk holder which provides the pressure boundary and clamps the disk into position, and the rupture disk (the actuating element).
