Non-metallic pipelines, particularly those made from Glass Reinforced Epoxy (GRE), are widely used due to their corrosion resistance, lightweight properties, and durability. However, there is a significant limitation in the ability to assess the structural integrity of these pipelines. Traditional damage detection techniques used in metallic pipelines are not directly applicable to GRE because of its composite nature and distinct mechanical behavior. This creates a critical gap in monitoring and maintaining non-metallic pipeline systems. This study aims to assess the feasibility of using the b-spline impulse response function to detect damage in GRE pipelines. By adapting this method, which has been successfully applied to structural steel, we seek to evaluate its effectiveness in identifying defects and material degradation in GRE. The methodology involves modeling the dynamic response of GRE pipelines under load. The b-spline impulse response function will be applied to analyze these responses, as outlined in previous work on 'B-Spline signature responses in structural change detection: method development.' Vibration data will be collected and processed to detect changes in response patterns that indicate potential damage. The method will be adapted to account for GRE’s unique composite structure. The expected outcome is the successful adaptation of the b-spline impulse response function for GRE pipelines, demonstrating its ability to identify the presence of damage. This method offers a non-invasive tool for assessing the structural integrity of GRE pipelines, contributing to safer and more reliable maintenance practices. The study could have a significant impact on how GRE pipelines are monitored and maintained, providing a reliable approach for ensuring their long-term functionality.
