Under the vision of "dual carbon", hydrogen energy, as an important tool for future energy transformation, is moving from technical exploration to large-scale application. Whether it is urban energy upgrading or industrial clean transformation, there is a basic question that cannot be avoided: How can hydrogen "run" safely and efficiently? One of the answers is Seamless Tube. With the rapid construction of hydrogen energy infrastructure, this metal material, which was once regarded as a traditional component, is reshaping its industry positioning and emerging in the wave of "new pipeline economy".
The development of hydrogen energy is not only an energy proposition, but also the core of a new round of industrial upgrading and infrastructure reconstruction. Hydrogen refueling stations, hydrogen transport vehicles, hydrogen storage equipment, industrial hydrogen supply systems... Behind these systems, the "pipeline" is the core of connection. The particularity of hydrogen - small molecules, easy leakage, high pressure, and high activity - determines that only seamless pipes with extremely high technical barriers can play the leading role. This marks the rise of a new infrastructure system - the "new pipeline economy" dedicated to hydrogen energy. The seamless pipe industry chain is in a critical stage of rapid transition from "general type" to "hydrogen energy dedicated type".
In hydrogen energy infrastructure, seamless pipes are not only material products, but also a technical solution. In order to meet the extreme requirements of "high pressure, high corrosion, no leakage, and zero fault tolerance" in hydrogen energy use scenarios, the manufacturing end is undergoing an all-round innovation: from ordinary carbon steel to low-carbon alloy steel, 304/316L stainless steel, nickel-based alloys and other hydrogen-resistant materials; these new materials have stronger corrosion resistance, ductility and resistance to hydrogen molecule permeability, and are the core of building a hydrogen energy safety system.
This means that Seamless Tube is upgrading from a general "material part" to a strategically significant "hydrogen-level basic component", and its R&D and manufacturing thresholds have been greatly improved.
From China's "Hydrogen Corridor" to Germany's "Hydrogen Backbone", to Japan and South Korea's large-scale urban hydrogen energy system layout, hydrogen pipelines are becoming the new protagonist of global energy infrastructure. The number of hydrogen refueling stations in China has exceeded 400, with more than 1,000 planned, and the annual growth rate of demand for supporting high-pressure seamless pipes exceeds 20%; Europe plans to build 40,000 kilometers of hydrogen pipelines by 2030, and puts forward new "gas-specific regulations" requirements for seamless stainless steel pipes; global high-end Seamless Tube manufacturers are saturated with orders, and many companies have started double-shift production lines. The logic of "rigid-demand pipelines" in the hydrogen energy era is accelerating the transition of the entire seamless pipe industry chain.
