LOX Equipment 1920 Oil Field — 1920 gal Horizontal Tank

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

This tank is listed as ASME/DOT certified. ASME certification allows stationary installation at your facility, while DOT certification would permit transport if the unit meets current highway transport requirements. You'll need to verify the actual nameplate certifications and whether the DOT rating is current, as DOT certification requires periodic requalification and may have lapsed since 1977.

What is the MAWP and capacity at service pressure?

The pressure rating is listed as 46 PSIG and capacity is 1,920 gallons. For cryogenic service, effective capacity depends on fill limits and working pressure—typical LOX service runs below MAWP with ullage space, so ask the seller for the nameplate MAWP, design temperature range, and what fill percentage was used in oil field service.

What should I inspect before putting it into service?

On any 1977 cryogenic tank, prioritize the vacuum integrity of the annular space, inner vessel condition, and all pressure relief devices which may be obsolete or out of hydro test date. Check for external corrosion on supports and jacket, verify all original nameplates are intact, and have the seller provide radiographs or previous NDE records if this will store LOX or other oxidizers. Given that this unit could not be located during inventory, confirm its physical condition and that all components including valving, instrumentation ports, and fill/withdrawal connections are present.
