“…To explore the influence of the forming medium on the performance of a rupture disc, hydraulic oil and air were compared in this study. Further, the size of the diameter of the forming die and the change in the thickness of the base material not only determine the venting diameter of the rupture disc but also have a certain influence on the formation of the rupture disc [37,38]. Therefore, this study included four die diameters (50 mm, 80 mm, 100 mm, and 150 mm) and three plate thicknesses for each diameter.…”

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.

“…Rupture disc is an important safety relief valve, which is often used for pressurized vessels and pipe in the petrochemical industry [1,2,3,4,5]. When the system pressure is suddenly increased, the greater pressure in the system can be released through the bursting of rupture disc, avoiding the occurrence of explosion for pressurized vessels and pipes as well as the following significant casualties and economic losses [6].…”

One conventional domed slotted rupture disc, which was fabricated with Inconel 600 alloy, was used in reaction kettle. It was burst after only 2000 times of operational circles. The burst causes were investigated. Morphologies of the fracture were observed by scanning electron microscope and the relatively chemical compositions were analyzed by energy dispersive spectrometer. Meanwhile, metallographic microstructures were also observed and analyzed for the material of the failure of the rupture disc. The results show that the bursting of the rupture disc was caused by fatigue fracture.
