US Steel ASME Pressure Vessel — 38.9 cu ft, 16" × 36' × .738"

Is this ASME or DOT rated, and what does that allow me to do with it?

This vessel is ASME-coded, which qualifies it for stationary pressure service at industrial facilities. ASME vessels are typically used for compressed air storage, nitrogen buffering, gas distribution headers, and similar fixed installations where DOT transportation certification is not required. You'll need to verify the code year and nameplate details to confirm compatibility with your jurisdiction's inspection requirements.

What is the requalification or inspection status?

The listing states the vessel has been inspected in stock condition, but does not provide dates or documentation for the most recent internal inspection, hydrostatic test, or jurisdictional certification. ASME pressure vessels in stationary service typically require periodic internal and external inspection per the National Board Inspection Code or local authority requirements, with intervals commonly ranging from 1 to 10 years depending on service and jurisdiction. Request copies of the most recent inspection reports and confirm whether a new hydrostatic test or authorized inspector certification will be required in your state before installation.

What should I inspect before putting it into service?

Verify that the ASME nameplate and code stamp are legible and match any documentation, then examine all welded seams, nozzles, and penetrations for cracks or corrosion. Measure actual wall thickness with an ultrasonic gauge at multiple points to confirm it meets or exceeds the nameplate minimum after accounting for corrosion allowance—the listed .738" is likely the as-built thickness, not current. The lack of stated service history means you should treat this as unknown previous contents; confirm compatibility with your intended gas, inspect internal surfaces if possible, and follow your facility's commissioning procedures including hydrostatic testing if previous service involved corrosive, toxic, or incompatible media.
