Cryogenic 600 Gallon 50 PSI Tank on 20 ft Goose Neck Trailer LIN/LAR Service

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

The listing does not provide current vacuum performance or Normal Evaporation Rate data. For a vessel built in 1961, vacuum degradation is common and these figures are essential to assess usability—request a recent vacuum gauge reading in microns and NER in gallons per day or percentage of capacity. On older cryogenic vessels, expect vacuum space contamination that may require re-evacuation or perlite replacement.

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

The listing confirms ASME Section VIII, Div. 1 certification with National Board Number 17706, but does not state whether the physical nameplate is readable or whether the U-1A manufacturer's data report is on file. Both documents are critical for inspection, recertification, and jurisdictional acceptance—request photos of the nameplate and a copy of the U-1A before committing to purchase.

What is involved in relocating and re-commissioning it?

The unit is a gooseneck trailer-mounted vessel located in Waxahachie, TX, requiring a fifth-wheel-equipped truck for transport and compliance with DOT and state regulations for wide load or oversize permits depending on trailer width. Re-commissioning typically involves jurisdictional pressure vessel inspection, vacuum system evaluation, relief valve recertification, and potentially vacuum pump-down or insulation repair if NER is out of spec. Confirm the trailer's road-worthiness, DOT compliance, and current registration status with the seller.
