Gaseous Hydrogen Safety Considerations
Material compatibility for hydrogen piping depends on application-specific factors, with guidance provided by ISO 11114, ASME B31.12, and NFPA 2.

Acceptability of materials is highly dependent on the specific application. Applied stress levels, exposure to contaminants, the operating temperature, the partial pressure, and number and…

Natural gas-hydrogen blends require pipeline material compatibility, odorant effects, and equipment modifications to ensure safety and operational reliability.

Hydrogen has been transported safely through pipelines for over 50 years. There are dozens of pipeline networks in safe operation globally, with several individual networks that approach up to…

Transporting hydrogen in pipelines requires material compatibility considerations and adherence to evolving standards like ASME B31.12 and B31.8.

Hydrogen affects the mechanical properties of most materials. For example, hydrogen reduces the
fracture toughness and increases the fatigue crack growth rate in steels. There is a significant…
