The composite rupture discs are a safety device that burst at the specified pressure and prevent overpressure and damage to equipment by releasing the fluid at high flow rates. The burst pressure is determined by the bulge formed and then slotted sheet metal. In the hydraulic bulge-forming stage, the sheet is subject to biaxial stress, and after slotting, it is subject to uniaxial tensile stress. Due to the change in the loading type, the sheet has a nonlinear strain path during the bulge-forming and burst test after slotting. In the nonlinear strain paths, the equivalent failure strain changes according to the strain path. In this paper, based on the FEM simulation results and experimental tests, the relationship between plastic failure strain in uniaxial tensile state and the maximum pre-strain due to bulge forming is investigated. According to the results of this paper, when the sheet sufficiently forms under hydraulic pressure, the maximum strain in hydraulic bulge-forming and the equivalent failure strain after slotting are equal. Based on this result, analytical relations were developed to predict the burst pressure of composite rupture discs. This relation estimates the burst pressure of composite rupture discs with an average error of about 13%.

“…In general, the venting effect of a rupture disc is closely related to the parameter referred to as burst pressure, and many studies have proposed a classic method to calculate the burst pressure of a rupture disc [20][21][22]. With the application of the finite element numerical simulation method in design engineering, great progress has been made to develop calculation models of the burst pressure of rupture discs [23,24]. However, few studies have been performed on the effect of production conditions on the burst pressure of rupture discs.…”

Rupture discs, also called bursting discs, are widely used in pressure vessels, pressure equipment, and pressure piping in process industries, such as nuclear power, fire protection, and petrochemical industries. To explore the relationship between the burst pressure of reverse-acting rupture discs and their production, two common manufacturing methods, air pressure moulding and hydraulic moulding, were compared in this study. Reverse-acting rupture discs that complied with the form recommended by API 520-2014 were prepared with four release diameters, and burst pressure tests were carried out. These results showed an obvious negative correlation between the forming pressure of rupture discs and their actual burst pressure for all experimental samples. Further study showed that the main reason for this correlation was a reduction in thickness at the top of the rupture disc caused by large plastic deformation during compression moulding. To explore the relationship between the thickness reduction effect and moulding method, this study defined the “relative ratio of thickness reduction” and concluded that the effect of decreasing the thickness of the rupture disc was more obvious for rupture disc substrates with less flexural rigidity. The above conclusions have important significance for guiding the control of the burst pressure of rupture discs.

Bursting disc overpressure relief device services as the last safety barrier in preventing catastrophic overpressure of the pressure vessel. The design of ultra-high pressure bursting disc device is a tough engineering issue as it requires both strength and sealing reliability under ultra-high working pressure. In this paper, a novel ultra-high pressure bursting disc device is proposed as well as the sealing structure is designed. Firstly, the novel bursting disc device structure is introduced. Then, the wall thickness of the sealing ring is designed based on elastoplastic mechanical analysis. Numerical simulation is also conducted to investigate the mechanical and sealing performance theoretically. At last, the strength and the reliability of the sealing performance is proved by hydraulic burst test.
