Presentation Synopsis

Updated for May 2020, this webinar shows how a technology that’s proven effective in critical power generation applications is eliminating the costly, time-consuming challenge of seizure-prone fitted (T/G) coupling bolts during planned outages. It highlights recent cases that demonstrate this technology’s value in the field. Further, it suggests preemptive steps that onsite personnel can take to minimize flange-bolt faults in future coupling maintenance situations.

Key Takeaways for Users

  • A look at the critical-path threat that occurs in turbine/generator (T/G) coupling flanges, when fitted bolts seize in their bores.

  • The downsides and risks of using conventional bolts for turbine/generator couplings.

  • An understanding of the principles of mechanical expansion bolts – what they are, how they work, and how they alleviate the problems of conventional bolts.

  • Case studies demonstrating how mechanical expansion bolts have been successfully used in these applications.
