Phased array ultrasonic testing for hot melt joint of thick wall high densitypolyethylene pipe in nuclear power plant
摘 要
分析了核电厂厚壁高密度聚乙烯管道热熔接头体积检查的主要难点。基于对高密度聚乙烯材料的声学性能和相控阵超声声场的建模分析,定制了自聚焦相控阵超声探头和特殊结构相控阵水楔块,有效解决了壁厚大于90 mm的高密度聚乙烯热熔接头的超声检测问题。通过对国内某核电站厂用水系统32英寸高密度聚乙烯管道的现场检测,验证了该检测技术的有效性。
Abstract
The main difficulties of the volume inspection for thick wall HDPE pipe hot melt joint were analyzed. Based on the acoustic properties of HDPE material and the acoustic field modeling analysis of phased array ultrasonic, self-focusing phased array ultrasonic probe and special structure water wedge are customized, which effectively solves the ultrasonic detection problem of HDPE hot melt joint with wall thickness greater than 90 mm. The effectiveness of the detection technology was verified by the field inspection of 32 inch HDPE pipeline of the water system in a nuclear power plant.
