Option A utilizes traditional prescriptive engineering design. It relies on standard, pre-established allowable stress tables and material specifications. Because it assumes worst-case material degradation without project-specific testing, Option A requires highly conservative safety factors, resulting in thicker pipe walls and higher initial material costs.

Hydrogen is often stored and transported at very high pressures (up to 15,000 psi or more), requiring robust wall thickness calculations provided in the code. Key Sections of the Code Materials:
The Future of Energy: Navigating ASME B31.12 for Hydrogen Piping
Requirements for volumetric examination (Visual, Radiographic, and Ultrasonic testing) are significantly higher than those found in standard B31.3 process piping codes.
