Abstract

An elastomeric expansion joint is a flexible connector fabricated of elastomers, fabrics and, in some cases, metallic reinforcements. The function of the expansion joint is to relieve stress in piping systems due to thermal fluctuation, vibration and/or piping settlement. In safety related applications, such as piping systems in nuclear power plants where the performance of the expansion joint is critical, the design must be verified to ensure all requirements are met. The objective of this project is to implement finite element as a design tool to aid the design and analysis of the expansion joints. An extensive study of a 6-inch ID open arch expansion joint was performed to obtain its pressure handling capabilities as well as the spring rates, both analytically and experimentally. The analytical and experimental results showed reasonable correlation. The study showed that finite element is an economical and effective tool for the design and analysis of expansion joints.
