Currently, Multilayer pipes are increasingly preferred over single-layer alternatives due to their enhanced mechanical and chemical properties. This research establishes governing equations for longitudinal guided wave propagation in multilayered pipes, calculating displacement fields and dynamic stresses. Dispersion curves and group velocity were derived based on boundary conditions, with ABAQUS finite element simulations validating the analytical results. The study examined how Epoxy layer thickness, configuration, and mechanical properties affect wave propagation in both two-layer and three-layer pipes. Results demonstrate that these parameters can significantly alter longitudinal guided wave propagation speeds in multilayered pipe systems.
