Recently, Hebei Canghai Nuclear Equipment Technology Co., Ltd. (referred to as “Canghai Nuclear Equipment”) succeeded in securing the contract for the 92-kilometer hydrogen pipeline project running from Damao Banner to Baotou city, thanks to its advanced pipeline technologies and system solutions. With its robust technical capabilities and high-quality products, the company became the main supplier for this project, contributing to the establishment of an efficient and safe green hydrogen transportation network. This not only demonstrates the company’s outstanding capabilities in pipeline manufacturing, but also marks a significant breakthrough for the company in the field of pipelines for new energy transmission. https://p3-sign.toutiaoimg.com/tos-cn-i-axegupay5k/aedb30f346f64a1b98aa38c46ab34424~tplv-tt-origin-web:gif.jpeg?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1764887947&x-signature=vwOAP1Q63%2BkOxArCe3DId0ebV20%3D This project serves as a key branch of Inner Mongolia Autonomous Region’s green hydrogen transportation network, which features one main pipeline and two ring pipelines with four exit points; it is approximately 190 kilometers long and acts as an important link between green hydrogen production sites and industrial users. Once the project is operational, it will enable the long-distance, large-scale, and cost-effective transportation of high-purity hydrogen, with an expected 80% reduction in the costs associated with hydrogen transportation. This will result in a yearly carbon reduction of 2.5 million tons, providing strong impetus for the green and low-carbon transformation of key industries such as steel and chemicals. https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/5522eb93aa7b28470e23652d23684eb3~tplv-tt-origin-web:gif.jpeg?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1764887947&x-signature=riPZ%2B8u9PrQRPoAE7Uqa63r2Lxo%3D Facing common industry challenges such as low density, high permeability, and flammability of hydrogen, there are extremely high requirements regarding the sealing performance and safety of materials used in transportation pipelines. Leveraging its years of technical expertise in energy transmission, Canghai Nuclear Installation established a dedicated R&D team to carry out multiple rounds of material optimization and process development. As a result, it succeeded in creating hydrogen pipeline systems with excellent resistance to hydrogen corrosion and permeation, along with an intelligent monitoring and maintenance system that significantly enhances the safety and stability of long-distance hydrogen pipelines. Of particular importance is the \"key manufacturing technologies for L360 steel pipes and L415 hot-bent pipes used for hydrogen transport\", independently developed by Canghai Nuclear. Significant breakthroughs have been achieved in terms of material property control and welding processes, enabling high toughness in weld areas with low residual stress; this meets all the stringent technical requirements for the long-distance transportation of green hydrogen. This technology has been rated as being at the leading level in China, providing a core guarantee for the high-quality construction and safe operation of the project. https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/c6ffb653d68ff1422f22e548ccc634c6~tplv-tt-origin-web:gif.jpeg?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1764887947&x-signature=ppACb2CEi2COr%2Bcc51L1gnXlVUs%3D As an important player and technology driver in the field of hydrogen energy infrastructure, Canghai Nuclear Equipment always adheres to innovation-driven development, striving to provide safe, efficient, and green pipeline system solutions for the clean energy sector. This extensive involvement in China’s first hydrogen transport pipeline represents not only a significant milestone in the company’s strategic shift from traditional energy equipment to the new energy sector, but it also demonstrates its commitment to achieving the \"dual carbon\" goals and contributing to the optimization of the energy structure.
