Research on the Fire Hose Burst Issues in the Stator of The Hydraulic Power Plant

The safety issue of technical water supply pipelines in hydroelectric power plant has been an ingrained problem, especially for the old hydraulic power plants. On the one hand, the original design and manufacture are inferior in quality; on the other hand, as the corrosion aggravates over time, water leakage and seepage frequently arise. In acute cases, the workshop may be flooded and other major accidents may occur accordingly. Starting with an accident that the fire hose of stator broke apart, this paper analysed the causes for pipeline break and presented relevant rectification scheme. It has provided technical guidance for maintaining and reconditioning the same type of water pipes.
