Our hydrogen storage permeable stainless steel tubes are specially developed for hydrogen energy applications, enabling controlled hydrogen permeation and diffusion in metal hydride storage systems, hydrogen purification, and membrane-based separation processes. These tubes feature a uniform microporous structure, high permeability, and chemical stability, making them ideal for next-generation hydrogen storage and release systems.
✅ Controlled Hydrogen Permeation
Engineered microstructure supports steady-state hydrogen flow under pressure differentials, enhancing safety and storage efficiency.
✅ High-Temperature Tolerance
Operates effectively at temperatures up to 600–800°C, compatible with metal hydride hydrogen release systems.
✅ Corrosion & Oxidation Resistant
Made from 316L, Inconel, or Hastelloy, resisting embrittlement and oxidation under repeated hydrogen cycling.
✅ Excellent Mechanical Strength
Withstands internal hydrogen pressure, repeated thermal cycles, and long-term system operation.
✅ Customizable Porosity & Wall Thickness
Tailored to meet different hydrogen flow rate, permeation pressure, and response time requirements.
