国内首条跨省绿氢管道项目首批纯氢输送管下线

Core Viewpoint - The article highlights the significant advancements in the hydrogen energy sector, particularly focusing on the successful production of high-quality hydrogen transport pipes, which are crucial for large-scale hydrogen delivery systems [2][4][5]. Group 1: Hydrogen Pipeline Project - The first cross-province, long-distance, large-scale green hydrogen pipeline project in China has successfully produced the first batch of 50 buried arc-welded straight seam pure hydrogen transport steel pipes [2]. - This project involves the demonstration pipeline from Ulanqab City in Inner Mongolia to the Beijing-Tianjin-Hebei region, marking a significant step in hydrogen transportation infrastructure [2]. Group 2: Technological Innovations - The newly produced pure hydrogen transport pipes are designed specifically for the hydrogen energy sector, utilizing advanced straight seam submerged arc welding technology [4]. - These pipes exhibit ultra-high purity and fine grain size, which effectively reduces the risk of hydrogen embrittlement, ensuring long-term stable operation in high-pressure pure hydrogen environments [4]. Group 3: Industry Impact - The successful trial production of these pipes signifies a major breakthrough in core manufacturing technology for long-distance pure hydrogen pipelines, providing essential technical support for large-scale, low-cost hydrogen transportation [5].
