介绍了多层包扎压力容器的声发射检验和安全评定方法及14台氢氮气储罐的声发射检验和安全评定结果。结果证明多层容器第二次升压过程中呈现单层容器一样的弹性特征。
The acoustic emission testing and safety evaluation of multi-layer bandaged pressure vessels and the acoustic emission testing and safety assessment of 14 hydrogen-nitrogen storage tanks are introduced. The result proves that the multi-layer container exhibits the same elastic characteristics as the single-layer container during the second pressurization.
