Analytical Assessment and Mitigation Strategies for Vibration in High-Pressure and Temperature Piping Subjected to Wall Thinning

Abstract Critical high energy piping lines such as the Main Steam Lines of a Nuclear Power Plant are subject to high pressure, temperature, and flow rates. Operational activities on these lines can produce large dynamic loads that can cause vibration problems resulting in high stresses. High vibration in these critical lines can lead to leakages, support failures, small bore piping failures, or a main steam line break. In aging nuclear power …
