流体输送管道的超声检漏技术

Ultrasonic leak—detecting technique for fluid—transporting pipes

超声检漏技术可以无损、快速、准确地检测出各种压力管道在输送液体或气体过程中所产生的泄漏位置。它既可对管道进行远距离检测定位,也可对压力容器、热交换器的密封性能进行检查.我们对泄漏所产生的声谱作了分析。

The principles of the ultrasonic leak—detecting technique used for fluid—transporting pipes is intrduced. The configuration of a newly-developed type of detector is given, Some experimental results with such a detector are introduced
