Avoiding the Costly Challenges of Seized Coupling Bolts in Hydropower Plants

Planned turbine outages are among the most expensive costs to power plants. Often, such costs to hydropower facilities are compounded by the seizing of conventional fitted bolts in turbine/generator (T/G) coupling flanges. These seized bolts require extensive, time-consuming labor through a number of methods – most of which typically fail. Unexpected expenditures and time delays contribute to the problem, but a solution does exist, as this white paper reveals. Cost comparisons and a hydropower plant case study are also included, making this a valuable and insightful resource for anyone involved in hydropower facility operations.
