Abstract
The work is a study of the influence of mixtures of gaseous hydrogen with natural gas with the ratios of 10 % Н2/90 % СН4 and 20 % Н2/80 % СН4 on PE-80 polymer pipes. The paper presents the results of complex structural investigations of the material of polyethylene pipes from PE-80, which were used earlier in the operating gas distribution networks of Ukraine, after 6 months of their hydrogenation. The influence of gas mixtures on the material structure was established, which is manifested in reduction of the quantity of the crystalline phase, polyethylene crystallite dimensions and their orderliness. No changes in the chemical structure of the polyethylene pipe material were found. 10 Ref., 5 Tabl., 8 Fig.
Keywords: Polyethylene, PE-80, natural gas mixtures, hydrogen mixtures, hydrogen transportation
