通过对水管锅炉上下锅筒的宏观检查、壁厚测量和金相组织检查,对上下锅筒的焊缝的性能进行了分析,并结合对水管锅炉上下锅筒制造缺陷的有限元计算,对水管锅炉上下锅筒的安全性进行综合评估。
Through the macro inspection, wall thickness measurement and metallographic examination of the upper and lower drums of the water tube boiler, the performance of the weld of the upper and lower drums was analyzed. Combined with the finite element calculation of the manufacturing defects of the upper and lower drums of the water tube boiler, Boiler upper and lower drum safety comprehensive assessment.
