Cryogenic Tank 18,000 Gallon / 175 PSI - LNG Storage, Vacuum Tested VS-18000SC-175CS-LNG

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

The listing states the tank has been vacuum tested and nitrogen purged but does not provide a current vacuum level or normal evaporation rate. Request the latest vacuum reading (typically measured in microns) and the NER in gallons per day or percent per day—these are the most critical indicators of insulation performance and will determine whether the vacuum jacket needs service before or shortly after installation.

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

The listing does not confirm data plate condition or U-1A availability. Both are essential—the data plate provides the National Board number, MAWP, and shell thickness required for recertification, while the U-1A manufacturer's data report is needed for jurisdictional filing and insurance approval in most states.

What is involved in relocating and re-commissioning it?

The estimated weight of 47,700–58,400 lbs and vertical orientation with four leg mounts mean you'll need a crane with sufficient reach for the approximate 39'–50' height, a foundation sized to the mounting pad configuration, and rigging that protects the vacuum jacket from impact. Re-commissioning typically requires vacuum verification, relief valve testing and recertification, trycock and gauge calibration, a pressure test if required by the jurisdiction, and possibly a new authorized inspection if the tank has been out of service beyond the jurisdiction's grace period—the listing notes schematics and drawings are included, which will be necessary for the work.
