Stringent control of welding consumables to avoid hard, brittle zones. 2. Design Considerations
— Hydrogen leaks are harder to detect and easier to ignite than other gases. B31.12's safety framework extends to leak detection, ventilation in enclosed spaces, and component compatibility.
ASME B31.12 strictly requires full penetration welds for branch connections, requiring full thickness welding. asme b 31.12 pdf
Focuses on hydrogen piping in industrial settings (e.g., chemical plants, refineries). It includes specific design, fabrication, and NDE (Non-Destructive Examination) requirements that are often more conservative than B31.3. Part PL (Pipelines):
Using inert gas (like nitrogen) when moisture contamination must be avoided. Stringent control of welding consumables to avoid hard,
Covers cross-country pipelines used to transport gaseous hydrogen over long distances. Why a Specific Code for Hydrogen?
The safe transportation of hydrogen through pipelines is critical to prevent accidents, injuries, and environmental damage. ASME B31.12 provides a framework for ensuring the integrity and reliability of hydrogen pipelines, which is essential for: It includes specific design
