The study aims to compare the performance of PVC-O with rigid PVC (PVC-U) and impact-modified PVC (PVC-HI) in terms of permeability coefficients and permeation rates, particularly focusing on temperature influence. The findings suggest that PVC-O pipes and M-110 couplers are viable options for hydrogen distribution networks, offering comparable or superior performance to traditional PVC materials, especially in cooler environments.
