Fiba 57.8 cu.ft. ASME Packaged Vessel — 5500 PSIG

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

This is an ASME Code certified vessel, which means it's designed for stationary installation at a fixed location. ASME vessels cannot be transported over public roads when pressurized—if you need portability, you would require DOT certification instead. This unit is suited for permanent or semi-permanent high pressure gas storage at your facility.

What is the MAWP and capacity at service pressure?

The listing states a working pressure of 5500 PSIG and capacity of 57.8 cubic feet. The MAWP (Maximum Allowable Working Pressure) should be stamped on the vessel nameplate and may differ from the working pressure rating—verify this on the data plate. If you need gas weight capacity or standard cubic feet at a specific fill pressure, ask the seller for the vessel's tare weight and the nameplate specifications.

What should I inspect before putting it into service?

Verify the ASME nameplate is legible and matches your required specifications, and inspect all valves and fittings for damage or contamination. Check the vessel exterior for corrosion, dents, gouges, or arc strikes, and confirm that pressure relief devices are present, in-date, and appropriately sized for your gas service. Even though the listing states new condition, confirm no shelf corrosion has occurred and that the vessel has been stored properly, then conduct or arrange for hydrostatic testing and inspection per your jurisdiction's requirements before pressurizing.
