The transport of hydrogen gas poses significant challenges to traditional pipeline materials such as stainless steel, primarily due to hydrogen embrittlement and corrosion. In this context, fiber-reinforced polymer (FRP) composites have emerged as a promising alternative, offering high corrosion resistance, lower density, and mechanical robustness. This study presents a comparative mechanical analysis using finite element simulations between E-glass/vinyl-ester composite and stainless steel pipes. The pipe geometries are designed according to industrial standards, and the structural response is evaluated under internal pressure conditions. This work emphasizes global structural behavior not just focusing on microstructural or morphological parameters. Results show that composite pipes provide significant advantages in terms of stress reduction and resistance reliability, and the potential use of composite pipelines in short-distance hydrogen transport networks and contribute to the ongoing development of lightweight, corrosion-resistant infrastructures for clean energy applications.
