Design Guidelines for Hydrogen Piping and Pipelines
No German title available
Brief description
This report provides recommendations and guidance to the ASME B31.12 Hydrogen Piping and Pipelines Section Committee for design factors for metallic and nonmetallic pipe materials when used in a dry hydrogen gas environment; design life considerations; nondestructive examination (NDE) recommendations; in-service inspection (integrity management) recommendations; research needs and recommendations. The scope of this report includes all common metallic piping and pipeline materials used in the construction of piping and pipeline systems, of seamless and welded construction; composite reinforced welded or seamless metallic-lined piping and pipelines that are currently commercially manufactured and for which technical design data is available; composite reinforced plastic-lined piping and pipelines that are currently commercially manufactured and for which technical design data are available. Design factors are developed considering the operating conditions, internal hydrogen environment within the piping and pipeline systems and the effect of dry hydrogen gas on the material of construction. Composite piping and pipeline line pipe are considered as hoop-wrapped construction with liners capable of withstanding longitudinal loads. Other examination and inspection recommendations are made using similar considerations. Research recommendations are made based on lack or vagueness of existing data or where the research results were not readily adaptable to engineering use.
