Division 3: Same scope as Divisions 1 & 2 except for pressures above 10,000 psig. Article KD-10: For all vessels in gaseous hydrogen transport and storage service. Each pressure component shall be evaluated for the specified fatigue cycle and shall meet the fracture toughness requirements in this article. These requirements are in addition to other requirements in Division 3.

A Project Team on Hydrogen Tanks is developing new rules for metallic and composite construction for hydrogen tanks operated at pressures up to 15,000 psig. Its strategy includes development of Code Cases for hydrogen specific applications written in conjunction with current rules published in the ASME BPV code, rather than development of a completely new code for hydrogen pressure vessels. Code cases are being written for expedited approval and publication of the technology and thus, allow for early implementation. The primary BPV code rules being addressed are Section VIII, Division 3 and Section X. The following actions have been completed: · Article KD-10 – Special requirements for fracture resistance of all-steel vessels in Section VIII, Division 3 · Code Case 2579 – Hoop-wrapped Composite Reinforced Pressure Vessels with Welded Liners for Gaseous Hydrogen Service; Section VIII, Division 3 · Code Case 2569 – SA-372 Steel Construction for Use in High-Pressure Hydrogen Application; Section VIII, Division 3 · Code Case 2563 – Aluminum Alloy 6061 Construction for Use in High-Pressure Hydrogen Applications; Section VIII, Division 3 Actions underway include: · Code Case for Fully Wrapped Fiber Reinforced Composite Pressure Vessels with Non-Load Sharing Liners for Gaseous Hydrogen Service for Section X application as a new class 3 up to 15,000 psi · Guidelines for in-service inspection of composite hydrogen vessels.
