Recently, Changbao Special Materials Division has completed the production and delivery of stainless steel tubes designated for the client’s water electrolysis hydrogen production project. The successful delivery of this batch of hydrogen-dedicated tubular products marks a pivotal technological breakthrough for Changbao Special Materials Division in the manufacturing of clean energy equipment, representing a solid stride forward on the emerging hydrogen energy track.

The billets for the delivered products are sourced from premium raw materials supplied by leading special steel manufacturers across the industry, guaranteeing high substrate purity and uniform microstructure from the source. Leveraging the company’s intelligent production lines, full-lifecycle digital quality control has been implemented throughout the project, covering closed-loop procedures including incoming material re-inspection, piece-by-piece production traceability, fully automated non-destructive testing and precision visual inspection. These rigorous measures secure consistent dimensional accuracy and uniform mechanical performance of every single tube. The finished tubes boast outstanding corrosion resistance, hydrogen embrittlement resistance and mechanical strength, capable of withstanding harsh operating conditions inside hydrogen production units and furnishing reliable support for long-term stable equipment operation.

As a core pillar driving the transformation of the energy system, hydrogen energy serves as a crucial engine for fulfilling the “dual carbon” goals and advancing the low-carbon transition of the real economy. China is currently accelerating demonstration projects and large-scale commercial application of renewable energy-based hydrogen production. Demand for high-performance stainless steel materials keeps surging in sectors such as liquid hydrogen storage & transportation and hydrogen refueling infrastructure construction. Aligned closely with national energy strategies and anchored on technological innovation and premium product supply, Changbao Special Materials Division actively embraces the transformation of the new energy industry and will keep expanding diversified application scenarios of clean energy and facilitate the optimization and upgrading of the energy mix.

This successful delivery of hydrogen-grade tubes stands as a landmark milestone for the commercialization of Changbao’s hydrogen energy products, as well as a fresh starting point for the enterprise’s in-depth advancement toward high-end equipment manufacturing. The Special Materials Division has built four specialized production lines for hot extrusion, high-end alloys, ultra-long precision tubes and ultra-clean tubes. Focusing on small-diameter precision seamless tubes, it commits to delivering localized solutions for critical materials applicable to thermal power, petrochemicals, offshore engineering, oil & gas exploitation, new energy, semiconductors and other sectors. Meanwhile, Changbao collaborates with partners to press ahead with technological R&D and market promotion of tubes for hydrogen transportation and storage, continuously improving its layout of key materials within the hydrogen energy industrial chain.

Going forward, Changbao will unswervingly uphold the green and low-carbon development philosophy, deeply integrate itself into the hydrogen energy industrial ecosystem, continuously upgrade manufacturing techniques, strengthen digital and intelligent quality management, and deliver more benchmark high-quality projects. With robust technological prowess and sophisticated high-end manufacturing capabilities, Changbao will contribute its share to the high-quality development of China’s new energy industry.
