摘要
Abstract
The permeability of hydrogen-blended natu-ral gas in PE pipes was studied through experiments.The test gases were 100％hydrogen,100％methane,and 5％hydrogen/95％methane respectively.The per-meability coefficients of the three gases were tested by pressure difference method,and the annual gas perme-ation volume per unit length of the pipeline for the three test gases was calculated.The calculation results show that when the gas composition is 5％hydrogen/95％methane,the gas permeability meets the require-ments and does not affect the safe use of PE 100 gas pipes.关键词
