摘要
对运行后的管材进行金相分析、蠕变孔洞观察及评级、高温持久实验等.采用综合分析法对其寿命进行预测.
Based on the metallographical analysis,observation,grading creeping holes as well as the experiment with the hightemperature creeprupture,this paper predicts the life expectancy of the overheater pipes after operation.Comprehensive analysis is adopted here.
