摘要
介绍了声发射检测技术的基本原理和特点,通过100 m3液化气储罐声发射检测的应用实例,说明了声发射检测的实施过程和结论分析,因其具有简捷、经济、灵敏度高,又能检测"动态"缺陷等特点,已发展成为金属压力容器检测和安全评定的主要无损检测方法之一。
This article introduces the basic principle and features of acoustic emission testing, 100 m^3 LPG vessel by Acoustic Emission Testing Application example explain the acoustic emission testing implementation process and the conclusion of analysis, because of its simple, economic, high sensitivity, and ＂dynamic＂ defect characteristics, it has developed into metal pressure vessels safety assessment testing and the main one of the NDT methods.
