| 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 cm 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. |
