New 26,000 SCFH 700 PSIG Horizontal Ambient Vaporizer — HBVP-26K-AL

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

The listing does not provide vacuum reading or NER (Normal Evaporation Rate) data. Request current vacuum gauge reading in microns and documented NER; these are the two primary indicators of annular space integrity on high-pressure cryogenic tanks. On units of this type, typical acceptable vacuum is below 50 microns and NER under 0.5% per day, but actual performance varies significantly with service history and maintenance.

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

The listing does not confirm data plate condition or U-1A availability. Request photos showing the full ASME data plate and copies of the U-1A manufacturer's data report before inspection; these documents are essential for verifying design pressure, MAWP, fabrication code year, and jurisdictional acceptance. Missing or illegible data plates typically require re-stamping processes through an authorized National Board repair organization.

What is involved in relocating and re-commissioning it?

The unit measures 120" L × 66" W × 97" H and will require heavy rigging and likely an over-width permit depending on transport orientation. Re-commissioning typically includes hydrostatic or pneumatic pressure testing to 700 PSIG, vacuum pump-down and leak testing of the annular space, safety valve testing and recertification, and potentially a jurisdictional CSD-1 inspection depending on your state or municipality. Request current vacuum hold test data and the date of last pressure test to assess the scope of recommissioning work.
