Code for Hydrogen Piping and Pipelines
• B31 Hydrogen Section Committee to develop a new code for H2 piping and pipelines
– Include requirements specific to H2 service for power,process, transportation, distribution, commercial, and residential applications – Balance reference and incorporation of applicable sections of B31.1, B31.3 and B31.8 – Have separate parts forindustrial, commercial/residential and pipelines – Include new requirements for construction, operation, and maintenance

Performance-Based vs. Prescriptive Standards
• Performance-Based
– – –States goals and objectives to be achieved Describes acceptable methods to determine goals and objectives have been met Focuses on desired characteristics of final product Prescribes materials, design,construction requirements without stating goals and objectives Focuses on requirements for processes to produce the final product

•

Prescriptive
– –

•

ASME standards include bothprescriptive and performance-based elements
