    摘要:

    工业氢气管道在氢能产业链中承担关键输送职能,但其材料在氢气环境下的氢致失效问题严重威胁系统安全性。本文系统分析了氢气对管道材料的损伤机理,重点阐释氢脆(低温氢损伤)与氢腐蚀(高温化学反应)的微观作用机制及影响因素;基于国内外标准对比,评述碳钢、奥氏体不锈钢等常用材料的氢相容性差异,指出低碳钢适用于中低压工况和奥氏体不锈钢适用于高压高纯氢环境最优选;结合化石能源制氢、工业副产氢及可再生能源制氢三类装置的工程案例,提出材料选型策略与防护建议。研究结果为氢气管道材料的标准化设计及安全运维提供理论依据,对推动氢能基础设施的轻量化与可靠性提升具有重要参考价值。

    Abstract:

    Industrial hydrogen pipelines serve a crucial function in the hydrogen energy supply chain, while hydrogen-induced material failures present substantial safety concerns. The study conducts a systematic analysis of hydrogen-induced damage mechanisms in pipeline materials, with particular emphasis on elucidating the microscopic processes and influencing factors of both hydrogen embrittlement (low-temperature hydrogen damage) and hydrogen corrosion (high-temperature chemical reactions). Through comparative evaluation of domestic and international standards, hydrogen compatibility differences among common materials including carbon steel and austenitic stainless steel are assessed. The analysis demonstrates that low-carbon steel is appropriate for medium- and low-pressure applications, whereas austenitic stainless steel represents the optimal solution for high-pressure and high-purity hydrogen environments. By incorporating engineering case studies from fossil fuel-based hydrogen production, industrial by-product hydrogen, and renewable energy-based hydrogen production systems, comprehensive material selection strategies and protective measures are developed. The research findings establish a theoretical framework for standardized design and safe operation of hydrogen pipeline materials, while providing valuable insights for improving the lightweight characteristics and reliability of hydrogen infrastructure.
