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.
