Practical Wave-Guide Methods for AE Testing of High/Low-Temperature Vessels Using Ordinary Sensors
摘 要
为了利用常温传感器对高/低温(深冷)容器进行声发射检测,提出了实用的柱-盘式、柱-帽式和挠性焊接型波导杆结构型式。针对一些特殊工况,提出了利用容器自身的外伸构件作为波导杆,以及对单层低温容器的水-冰耦合法的经济环保型波导方法。大量的现场声发射检测实践证明,波导方法可以满足绝大多数高/低温容器采用常温传感器进行声发射检测的需要,具有简单、实用、经济、效果较好等优点。
Abstract
Three wave-guide rods including disc-rod, cap-rod and flexible rod were designed so as to test high/low-temperature vessels using ordinary AE sensors. For some special conditions, some support/fixed members protruded from insulation and welded to vessel shells can be directly used as wave-guide rods, and water-ice coupling can be adopted in AE testing of cryogenic monolayer vessels. A lot of field testing practice shows that those recommended wave-guide methods are economical, simple, and practical, they meet the needs of AE testing of most high/low-temperature vessels using ordinary sensors.
