Overview

This analysis highlights how elastic interactions impact flange integrity and system reliability during hot bolting.

Key Points

  • The study reveals potential failures in bolted flange joints during the untightening process, leading to system risks.
  • By analyzing elastic interactions, researchers found ways to mitigate gasket damage and enhance flange performance.
  • This work involves detailed analysis of flange behavior to improve predictions and safety during hot bolting procedures.
  • The findings could enable safer disassembly operations, reducing the need for additional tools under calculated safety factors.
