摘要:

设计了一种基于聚乙烯材料的高阻隔、高强度、轻质非金属输氢管道,通过设计开发具有内管层、阻隔层、增强层和外保护层,有效避免了金属管道的氢脆问题,同时克服了承受压力有限及气体渗透的缺点。其中内管层及外保护层由聚乙烯(PE)树脂构成,阻隔层由铝箔、乙烯⁃乙烯醇共聚物(EVOH)及改性后的线形低密度聚乙烯(PE⁃LLD)组成,增强层由涤纶丝构成。结果表明,开发的输氢管道具有承压结构强度高、盘卷柔韧性能好、高阻隔、高强度,且抗气体渗透严密、使用寿命长等特点,能够满足氢能输送的要求。将为氢气输送行业提供一种操作安全、持久且高效的输氢管道方案,进而对氢能的能量转换及未来价值链的发展做出重要贡献。

Abstract:

This study presents the development of a novel non⁃metallic, multilayer composite pipeline designed for hydrogen transport. Constructed primarily from high⁃molecular⁃weight polyethylene, the pipeline features a four⁃layer structure: an inner tube, a barrier layer, a reinforcement layer, and an outer protective layer. This design effectively mitigates hydrogen embrittlement, a critical limitation of metallic pipelines, while simultaneously overcoming the low⁃pressure resistance and high gas permeability of conventional polymers. The inner and outer layers are composed of polyethylene resin, the barrier layer combines aluminum foil with a blend of ethylene⁃vinyl alcohol copolymer and modified linear low⁃density polyethylene, and the reinforcement layer consists of high⁃tenacity polyester yarn. The resulting structure exhibits high mechanical strength, excellent flexibility for coiling, superior barrier properties, and long⁃term durability. This work provides a safe, efficient, and lightweight pipeline solution that supports the growing infrastructure needs of the hydrogen energy sector.
