ASME BPV Project Team on H2 Tanks Meets in
Portland
John Koehr and Gerry Eisenberg, ASME
 The
ASME Boiler and Pressure Vessel Code (BPVC) Project Team on Hydrogen Tanks
met on February 15, 2006 in Portland, Oregon as part of the quarterly Boiler Code
Week meetings. The project team is developing new rules for stationary, transportable,
and portable tanks in hydrogen service at pressures up to 15,000 psi. The scope
includes metallic and composite materials as well as pressure vessels for metal
hydride storage. Key activities include:- Fracture resistance requirements:
A recommended new Article KD-10 has been proposed for ASME BPVC Section VIII Division
3, providing additional toughness requirements for all-steel pressure vessels
in Hydrogen service.
- Addition of new materials (e.g. Al alloy
6061) not already covered in Section VIII Division 3.
- Design Margins
for Composite Vessels: A technical report was prepared to address design margins
for composite tanks that will build upon the information developed in the Hydrogen
Standardization Interim Report for Tanks, Piping and Pipelines which was distributed
to the Project Team. The scope of this study includes stationary (e.g. storage)
and transport tanks; it does not include vehicle fuel tanks. The report provides
recommended design margins relative to short term burst pressure and interim margins
for long term stress rupture based on a fixed 15 year design life for fully wrapped
and hoop wrapped composite tanks with metal liners.
- New Code
Case for Composite Vessels: A draft Code Case is being developed by a Task Group
that covers the fabrication of fiber reinforced thermosetting plastic pressure
vessels for high-pressure service. The Case covers three applications of pressure
vessels, Class A-portable, Class B-transportable, and Class C stationary applications.
- Revision to Code Case 2390: expanding the scope of metallic lined
composite reinforced circumferentially wrapped storage and transport pressure
vessels to Hydrogen service at 15,000 psi.
- Metal Hydride Vessel
Design: A draft Code Case has proposed for Section VIII Division 1 application.
- Improved methods for inservice inspection.
