摘要
对运行了约８０００ｈ的废热锅炉换热管进行了室温、高温机械性能试验，扩口与压扁检验以及金相组织分析，结果表明，换热管材料性能没有发生明显变化。
For heat exchange tube of waste heat boiler had been operated about 8000 hours, the mechanical property test at ambient and high temperature mechanical property test, flaring test, flating test and metallographic structure analysis are carried into practice. The resulate state that the material performance of heat exchange tube are not distinctly changed.
