ISO 734026-1 — 1,522L Process Tank, 2,200 PSIG

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

The listing does not provide current vacuum quality or nitrogen evaporation rate data. Because condition verification is incomplete, you should request recent vacuum level readings (typically measured in microns or as annular space pressure) and NER figures from the seller before evaluating thermal performance. Cryogenic vessels of this age should show stable vacuum and NER below 2-3% per day for nitrogen service if the insulation system remains intact.

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

Data plate condition and U-1A form availability are not addressed in the listing. Both documents are critical for establishing ASME certification, fabrication code year, and legal ownership transfer for pressure vessels. Request confirmation that the nameplate is readable and that the original U-1A manufacturer's data report is on file before proceeding.

What is involved in relocating and re-commissioning it?

Relocation requires offloading the frame-mounted unit intact (verify lifting lug condition and total loaded weight with seller), transportation under DOT regulations if it retains pressure capability, and re-siting on a level pad with adequate clearances. Re-commissioning will require hydrostatic retest per jurisdiction—typically every 5 years for ASME vessels—vacuum verification, safety valve recertification, and possibly material recertification depending on the receiving facility's requirements and how long the unit has been idle.
