Fiba 40' x 24" ASME NB Cryogenic Storage Tank — 3,800 gal, 4000 PSIG

What is the current vacuum reading, and what is the NER?

The listing does not provide current vacuum level or normal evaporation rate data. For a new unit these figures should be available from factory testing; request the manufacturer's test report or data plate documentation showing vacuum hold time and NER at the time of fabrication. On cryogenic vessels, vacuum degradation over time is the primary mode of insulation failure, so baseline values are essential for establishing future inspection intervals.

What product has it held, and what can it be converted to?

The listing indicates new condition, so the vessel has not been in service. Cryogenic tanks are typically designed for specific products—LOX, LIN, LAR, or LNG—with material compatibility, vaporizer sizing, and relief device settings configured accordingly. The seller should confirm the intended service designation on the data plate, as converting between oxidizing and inert services requires thorough cleaning, material compatibility review, and potentially different relief and pressure-building coil specifications.

Is the data plate legible, and is the U-1A available?

The listing confirms ASME Section VIII Division 1 construction with National Board registration but does not specify U-1A documentation status. Request photographs of the data plate showing the NB number, MAWP, design temperature, and year of manufacture, along with the U-1A manufacturer's data report. These documents are required for jurisdictional acceptance and insurance coverage in most states.

What is involved in relocating and re-commissioning it?

The unit is a 40-foot packaged vessel that will require heavy rigging, an extendable trailer or lowboy, and escort depending on jurisdiction. Typical cryogenic tank installation includes foundation or saddle preparation, piping connections, electrical for pressure-building and instrumentation, and initial vacuum pull-down verification before product fill. Since this is listed as new, factory vacuum should be intact, but verify vacuum hold and conduct a pressure test per the installing jurisdiction's requirements before commissioning.
