This study evaluates the flexibility of a fiber-reinforced polymer (FRP) pipeline system, focusing on its ability to withstand various loads and stresses while maintaining structural integrity. Key aspects include analyzing FRP material properties, assessing pipe geometry, evaluating external and internal loads, and performing a flexibility analysis using CAESAR II software. The initial findings indicated that the stress levels exceeded permissible limits, necessitating adjustments in support positions and types. These adjustments successfully reduced stress levels to acceptable thresholds, ensuring reliable system performance. This study highlights the importance of meticulous design and continuous optimization to guarantee the safety and durability of FRP pipeline installations.
