摘要
压电超声腐蚀内检测技术检测灵敏度高,并能够直接对腐蚀缺陷进行深度量化,在液态在役管道腐蚀检测方面得到广泛应用。通过分析管道压电超声腐蚀内检测技术的基本原理,总结了国内外压电超声腐蚀内检测技术的发展现状,列举了现阶段国外知名检测公司3种较先进的压电超声腐蚀内检测器的产品性能、特点,指出了压电超声腐蚀内检测技术未来的发展方向,为中国管道压电超声腐蚀内检测技术的发展提供了参考。
Piezoelectric ultrasonic based corrosion in-line inspection technology is of high detection sensitivity and can quantify the depth of corrosion defects directly. Due to its advantages, it has been widely used in the corrosion inspection of in-service liquid pipelines. In this paper, the basic principles of piezoelectric ultrasonic based pipeline corrosion inline inspection technology were analyzed, and its development status at home and abroad was reviewed. Besides, the performance and characteristics of three currently advanced piezoelectric ultrasonic based corrosion in-line inspection tools developed by the well-known foreign inspection company were listed. Finally, the future development direction of the piezoelectric ultrasonic based corrosion in-line inspection technology was pointed out. The research results provide the reference for the development of piezoelectric ultrasonic based pipeline corrosion in-line inspection technology in China.
