DONG Peng, CHEN Ming, WANG Wentao, et al. Cause Analysis of Hydrogen Damage Induced Bursting of Waterwall Tubes in a Boiler[J]. 2017, 38(6): 61-63.DOI: 10.3969/J.ISSN.2095-3429.2017.06.015.
Bursting failure occurred on waterwall tubes in a power plant. Macroscopic inspection
chemical analysis
mechanical property testing and metallurgical analysis were adopted to examine the failed tube. The results indicated that the tube rupture was resulted from brittle fracture caused by hydrogen damage. The causes of hydrogen damage were analyzed and discussed.
