CCH Custom Build VPC-30K — 30,000 gal 700 PSI Cryogenic Storage Tank

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

The listing does not provide the current vacuum reading or normal evaporation rate for this tank. Ask the seller for the most recent vacuum measurement in microns and the daily NER as a percentage of capacity, and request documentation showing the trend over the past year if available.

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

The listing does not confirm data plate condition or document availability. Request photos of the nameplate showing the ASME stamp, National Board number, and design specifications, and ask whether the seller has the original U-1A manufacturer's data report and any U-3 reports from past reinspections.

What is involved in relocating and re-commissioning it?

The listing does not detail the tank's current condition or commissioning status. Cryogenic tanks of this age typically require vacuum re-pull and leak testing, pressure vessel recertification per the jurisdiction of installation, and replacement of instrumentation and relief devices that may no longer meet current codes; verify whether the inner vessel has been exposed to atmosphere, as that significantly extends the vacuum recovery timeline.
