The NDT Analysis for the Leakage Reason of Ammonia Synthetic Tower Shell
-
摘要: 对氨合成塔筒体泄漏情况进行了分析，提出了在制造过程中进行一次半厚度(30mm)射线检测，焊缝内表面进行100%磁粉检测。同时，在设备设计、制造和使用过程中应严格控制和管理。Abstract: The leakage reason of ammonia synthetic tower shell was analyzed. It was proposed that both radiographic testing at half thickness and magnetic particle testing for weld surface were necessary during manufacture. On the same time, the design, manufacture and management for equipment should be strictly controlled and managed.
