【Abstract】 Failure analysis method was discussed in this paper in the field of hydraulic power plant. It was mainly studied that related material fracture analysis and corrosion environmental analysis. A case was employed in this analysis process, which was concerned with draft tube bolts in a hydraulic generating unit. Component status was precisely evaluated by such analysis method, which can be very important for assessing safety of hydraulic unit.更多还原
