采用超声波测厚仪及现场用金相显微镜对E2 0 2A换热器主要部件的腐蚀状况和显微组织进行了检测 ,根据检测结果对E2 0 2A换热器的剩余寿命做了合理评估。
The corrosion status and microstructure of the main components of E2 0 2A heat exchanger were examined by ultrasonic thickness gauge and on-site metallographic microscope. Based on the test results, the remaining life of E2 0 2A heat exchanger was reasonably evaluated.
