Fiba ASME N.B. Packaged Vessel — 24.0 Gallons, 8000 PSIG

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

This is an ASME National Board coded vessel. ASME vessels are designed for stationary installation at industrial facilities and cannot be transported filled over public roads, which requires DOT certification. The 8000 PSIG rating and Grade J construction make it suitable for high-pressure gas storage in fixed locations such as tube trailers that remain on-site, gas cylinder filling stations, or process buffer storage.

What is the MAWP and capacity at service pressure?

The listing states an 8000 PSIG pressure rating and 24.0 gallon capacity but does not specify whether this is MAWP, test pressure, or working pressure, nor at what pressure the 24.0 gallon capacity applies. You should request the vessel's ASME U-1 manufacturer's data report and nameplate details from the seller to confirm the stamped MAWP, design pressure, and water capacity.

What is the requalification or inspection status?

The listing describes this as new condition but does not state whether it has an original hydrostatic test date, ASME certification paperwork, or National Board registration. For a new ASME vessel, you should request the U-1 form, mill test reports, and confirmation of National Board registration to establish the initial certification baseline for your internal inspection program.

What should I inspect before putting it into service?

Verify all nameplate data is legible and matches the U-1 form, confirm vessel registration with the National Board, and perform a visual inspection for shipping damage, particularly to nozzles, valve connections, and protective coatings. ASME Section VIII vessels at this pressure class typically require internal inspection and hydrostatic testing per the owner's inspection program before initial service, with particular attention to weld quality, thread condition on high-pressure connections, and proper torque on closure hardware if the vessel includes removable heads or plugs.
