| 摘 要： | 用扫描电镜（SEM）及能谱(EDS)分析等手段，分析加氢高压换热器Ω环开裂原因。结果表明，Ω环的开裂属于H2S应力腐蚀开裂，高的工作应力和壳程少量硫化氢的存在共同促使其开裂。

| Abstract: | Cracking ofΩ loop of high pressure hydrogenation heat exchanger was analyzed by means of morphology and microstructure analysis, chemical composition analysis, SEM micro-morphology analysis and EDS analysis. The results showed that the cracking of the sample was to be hydrogen sulfide stress corrosion cracking. The high working stress and a few of hydrogen sulfide in shell side induced the cracking of theΩ loop jointly. |

| Keywords: | heat exchanger &Omega loop hydrogen sulfide stress corrosion cracking |
