Phased array ultrasonic testing of dissimilar steel heating surface tubes in power station boilers

摘要: 异种钢对接接头广泛应用于电站锅炉受热面管中，其常用的检测方法主要为射线检测和常规超声检测。使用相控阵超声检测技术对某超临界电站锅炉异种钢受热面对接接头进行检测，取得了较好的检测效果。

Abstract: Dissimilar steel butt joints are widely used in power station boiler heating surface pipes. The common detection methods are mainly radiographic inspection and conventional ultrasonic testing. Phased array ultrasonic detection technology is used to detect dissimilar steel heating surface joints of a supercritical power station boiler and achieve a good detection results.
