摘要
通过材料性能测试、回火脆化倾向性评定和金相检验等 ,对一台旧换热器的安全性能进行了综合分析 ,实验结果表明 :该台已运行 10万小时的加氢换热器各项材料性能指标良好 ,经修复和改造后的换热器能满足安全使用要求 。
The safety properties of a used hydrogenation heat exchanger had been analyzed by means of material property testing, temper embrittlememt evaluation and metallographic observation. The result showed that material properties of the heat exchanger which had been in-service for over 100 thousands hours were satisfactory. The renewed heat exchanger which had been repaired and modified was capable to meet the requirements of safe operation and the waste equipment can be properly used.
