我国首次完成10兆帕高压氢气管道全尺寸放空试验

Core Viewpoint - The successful implementation of China's first full-scale 10 MPa high-pressure hydrogen pipeline venting test marks a significant advancement in hydrogen pipeline safety technology, filling a technical gap in the country [1][3]. Group 1: Test Significance - The venting test serves as a "safety simulation" for hydrogen pipelines, ensuring the safe and stable long-distance transportation of hydrogen, which is crucial for the widespread application of hydrogen energy [3]. - The test platform recreated various scenarios for safely venting hydrogen, including non-ignition and ignition combustion scenarios, under multiple pressure and operational conditions [3][5]. Group 2: Technical Achievements - The test successfully gathered critical parameters such as hydrogen concentration distribution, flame structure, thermal radiation intensity, and impact range, providing insights into the flow and diffusion patterns of high-pressure hydrogen during venting [5]. - The results of the test will directly contribute to the construction of large-diameter hydrogen pipelines, enhancing the safety level of pipeline operations [5]. Group 3: Industry Impact - The successful test addresses a key technical challenge in hydrogen storage and transportation, accumulating important experience for hydrogen energy safety technology in China [5]. - The findings will help improve safety standards in the hydrogen industry and promote coordinated development across various segments of the hydrogen energy supply chain, providing a solid foundation for the large-scale application of hydrogen energy in China [5].
