China's First Long-Distance Green Hydrogen Pipeline Accelerates Integration, Canghai Nuclear Equipment Leads New Breakthroughs in Hydrogen Transmission with Core Technology!

As the "wind and solar" resources of the vast grasslands are converted into green hydrogen, a critical energy artery is quietly taking shape, connecting the production and consumption of clean energy. Recently, Hebei Canghai Nuclear Equipment Science and Technology Co., Ltd. (hereinafter referred to as "Canghai Nuclear Equipment") has successfully secured the contract for the 92-kilometer hydrogen pipeline project from Damao Banner to Baotou City, leveraging its advanced pipeline technology and system solutions. With its robust technical capabilities and high-quality products, the company has become a major supplier for the project, contributing to the nation's efforts in building an efficient and secure green hydrogen transmission network. This not only highlights the company's exceptional strength in pipeline manufacturing but also marks a substantive breakthrough in the field of new energy transmission pipelines.

As a key branch line of the "One Trunk, Two Rings, and Four Outlets" green hydrogen transmission network in the Inner Mongolia Autonomous Region, the approximately 190-kilometer project serves as a critical link between green hydrogen production bases and industrial end-users. Upon commissioning, it will enable long-distance, large-scale, and cost-effective transportation of high-purity hydrogen, with projected reductions in hydrogen transport costs by 80% and annual carbon emission cuts of 2.5 million metric tons. This will inject robust momentum into the green and low-carbon transition of key national industries such as steel and chemicals.

Faced with industry-wide challenges such as low hydrogen density, high permeability, and combustibility, which impose extremely high requirements on pipeline materials for sealing and safety, Canghai Nuclear Equipment leveraged its years of technical expertise in energy transportation. The company established a dedicated R&D team, conducted multiple rounds of material optimization and process improvements, and successfully developed a hydrogen pipeline system with excellent resistance to hydrogen embrittlement and permeation. This system, integrated with an intelligent monitoring and maintenance framework, significantly enhances the safety and stability of long-distance hydrogen transmission networks.

Critically, Canghai Nuclear Equipment's proprietary key technologies for manufacturing L360 Steel Pipes and L415 hot induction bending pipes for hydrogen transmission have achieved major breakthroughs in material performance control and welding processes. These technologies enable high toughness in weld zones with low residual stress, fully meeting the stringent technical requirements for long-distance green hydrogen transportation. Recognized as domestically leading, this innovation provides core assurance for the project's high-quality construction and safe operation.

As a key participant and technological driver in the hydrogen infrastructure sector, Canghai Nuclear Equipment has consistently adhered to an innovation-driven approach, committed to delivering safe, efficient, and environmentally friendly pipeline system solutions for the clean energy ecosystem. Its deep involvement in the country's first major hydrogen transmission trunk line not only marks a significant milestone in the company's strategic transition from traditional energy equipment to the new energy sector but also demonstrates its commitment to fulfilling the "Dual Carbon" goals and advancing the optimization of the national energy structure.

From pioneering technological breakthroughs to executing major projects, and from manufacturing individual components to delivering integrated system solutions, Canghai Nuclear Equipment is charting a new course for hydrogen transport infrastructure through robust technological capabilities and forward-looking industrial strategy. In the near future, as this green hydrogen artery becomes operational, a steady flow of clean hydrogen will traverse the grasslands into urban and industrial heartlands, providing solid underpinning for China's green energy transition and high-quality development.
