压力容器定期检验中应优先选用超声方法检测埋藏缺陷

Priority Selection of the Ultrasonic Inspection Mthod for Embedding Defects Inspection in Periodic Survey of Pressure Vessel

分析了压力容器埋藏缺陷存在的特点,比较了不同检测方法最适用的对象,提出压力容器定期检验时应优先选用超声波方法对埋藏缺陷进行检测。

The characteristic of the embedding defects in pressure vessel was investigated.And the effects of different kinds of inspetion method for inspecting these defects were also compared in this paper.According to the above-methioned discussion results,the ultrasonic inspection was proposed to be the optimized method to inspect embedding defects in pressure vessel in periodic survey.
