Fiba 40' ASME N.B. Cryogenic Storage Vessel — 103 Gallons, 3,100 PSIG

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

This is an ASME vessel with National Board registration, which qualifies it for stationary installation at your facility. ASME vessels are built to Section VIII standards for fixed storage applications and cannot be transported over the road when charged, unlike DOT-certified cylinders. The National Board registration provides third-party verification of the ASME construction and enables tracking through the NB database.

What is the MAWP and capacity at service pressure?

The maximum allowable working pressure is 3,100 PSIG with a capacity of 103 gallons. The listing does not specify whether this capacity is water volume or rated cryogenic product volume at service pressure, so confirm with the seller whether the 103 gallons represents geometric capacity or usable cryogenic fluid storage at the working pressure.

What is the requalification or inspection status?

The listing does not provide hydrostatic test dates, last inspection records, or current certification status. For a new vessel you should receive the manufacturer's data report (U-1A), National Board Form U-2 if registered, and radiography reports. Confirm with the seller that all original fabrication documentation is available and ask whether it has been hydrostatically tested or placed into service.

What should I inspect before putting it into service?

Verify the nameplate data matches the documentation, check all welds and the outer jacket for shipping damage or corrosion, and confirm the vacuum integrity if this is a vacuum-insulated unit. Inspect all valves, pressure relief devices, and instrumentation ports for completeness and damage, and verify that pressure relief capacities match your intended service. Your jurisdiction may require an authorized inspector's review and hydrostatic test before initial installation, even on new vessels.
