- 石油、化工、电力等行业的容器设备很多是在50～450℃的温度下工作,有的容器设备还要求在不停产条件下对其缺陷进行监控。高温超声波检测技术可以满足上述容器设备的检测要求。文章通过研究高温对超声波声速、斜探头折射角、超声波衰减、探头发射超声波强度以及缺陷检出率的影响,提出了对容器设备进行高温超声波检测的方法、具体检测步骤和操作要点等。
Many kinds of vessels and equipment in petroleum, chemical and electric power industries operate at 50 ～ 450 ℃, some of them require monitoring and controlling their defects under continuing production condition. High temperature ultrasonic inspection is able to satisfy those inspection requirements of the vessels and equipment. This paper investigates the effects of high temperature on ultrasonic velocity, refraction angle of inclined probe, ultrasonic attenuation, emitting strength of ultrasonic probe and defect detectable ratio, and provides practical methods of high temperature ultrasonic inspection for vessels and equipment, as well as concrete inspection procedure and key operational points.2008,3(3): 57-60 收稿日期：2007-9-27分类号：TQ050.7作者简介：雷胜军（1970-），男，湖北黄冈人，高级工程师，2003年毕业于武汉大学机械及材料工程系，现从事特种设备的检测和研究工作.参考文献：
