| 摘 要： | 针对某公司制氢站一台冷却器换热管多处腐蚀穿孔泄漏现象,通过对其换热管化学成分分析、管子表面腐蚀产物形貌分析、腐蚀产物成分能谱分析、管子金相组织分析和水质分析,结果发现换热管失效原因是与循环冷却水质和流速缓慢有关。

| Abstract: | With respect to the leakage due to corrosion occurred in several locations in the heat transfer tubes in a cooler used in a hydrogen generation station, the chemical and metallurgical composition of the tubes, the surface form and the composition energy spectrum of the corrosion products and the water flowing in the tubes were analyzed. The result showed that the failure of the tubes was due to the composition of the cycling water and the low velocity of the water. |
