基于超声检测的临氢设施氢损伤识别与评估方法研究
Research on the Identification and Assessment Method of Hydrogen Damage in Hydrogen-exposed Facilities Based on Ultrasonic Detection
摘要
Abstract
Aiming at the problems such as low accuracy of damage detection,delay of damage detection stage and difficulty of off-line outage detection,a new method of damage identification and evaluation based on ultrasonic detection was proposed.First,X52 pipeline steel samples with different degrees of hydrogen damage were prepared by electrochemical hydrogen charging method,and the metallography morphology of each group of samples was analyzed.Then,ultrasonic detection experiments were carried out.Ultrasonic signal parameters that could reflect the state of hydrogen damage were extracted by systematically studying the ultrasonic attenua-tion characteristics and nonlinear response characteristics of different degrees of hydrogen damage.The relation-ship curve of attenuation coefficient α-nonlinear paramenter N-hydrogen charging time T was established.The results showed that both attenuation coefficient and nonlinear paramenter were significantly correlated with the hydrogen damage degree of materials.These parameters can jointly characterize the hydrogen damage state of materials,and provide a method reference for the subsequent safety assessment of in-service hydrogen facilities.关键词
