摘要
Abstract
Considering that existing technical specifications rarely provide detailed guidelines for evaluating the service life of the rupture discs,taking the low-pressure cylinder rupture disk in the steam turbine of a nuclear power plant as an example,by analyzing the factors affecting its lifespan,comprehensive fatigue and burst tests were carried out on the rupture disk.Additionally the material quality was inspected and defects were detected for metal components,and accelerated aging tests and performance comparisons were carried out for non-metal components.The results indicate that after 100 pressure cycles,the rupture disk maintains its performance within the design parameters,demonstrating robust fatigue resistance.Both microscopic analyses of metal components and accelerated aging tests of non-metal components verified the high stability and long life of the material.Under existing service conditions and replacement cycles,the influences of primary factors influencing the lifespan of the rupture disk have limited impact on its operational damage.The decision to double the replacement cycle is substantiated by theoretical and experimental data.This research provides valuable guidance for the application,maintenance,and replacement strategies of rupture disks in engineering projects.关键词
