Enric ASME Hydrogen Storage Vessel – 186 Cu Ft | 8,000 PSIG Design Pressure | Skid Mounted (8T)

Is this ASME or DOT rated, and what does that allow me to do with it?

This is an ASME-coded vessel, which certifies it for stationary installation at your facility. ASME vessels are designed for permanent or semi-permanent mounting and cannot be transported filled over public roads—DOT certification is required for transport service. The skid mounting allows relocation when empty, but this unit is intended for fixed-site hydrogen storage applications.

What is the MAWP and capacity at service pressure?

The working pressure is 7,000 PSIG with a design pressure of 8,000 PSIG. The water volume is 186 Cu Ft; to determine usable hydrogen capacity at your operating pressure, you'll need to apply the compressibility factor for hydrogen at your specific temperature and pressure conditions. The listing does not provide gas capacity in SCF, so request that calculation from the seller if needed.

What should I inspect before putting it into service?

Verify all ASME U-1 manufacturer's data reports are present and review the hydro test documentation to confirm the vessel meets the stated 10,400 PSIG test pressure. Inspect the SK-372 Gr. J Cl. 70 tube material for external corrosion, impact damage, or arc strikes, and check all manifold connections, isolation valves, and pressure gauge for leaks using appropriate hydrogen-rated methods. Given the -40°F MDMT rating and hydrogen embrittlement concerns, have a qualified inspector review the vessel's suitability for your specific service conditions and confirm compliance with your jurisdiction's hydrogen storage requirements.
