10 Gallon 3600 PSI Type 1 CNG Tank Good through 10/2034

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

This is a DOT-rated CNG cylinder (Type 1 designation indicates all-metal construction under DOT standards). DOT cylinders are designed for transportation and mobile storage applications, whereas ASME vessels are typically used for stationary installations; this unit is suited for vehicle fuel storage, mobile refueling, or transport applications where DOT compliance is required.

What is the MAWP and capacity at service pressure?

The maximum allowable working pressure (service pressure) is 3600 PSI at 21°C. Storage capacity is 10 gallon / 80 liter; the listing does not specify the actual gas volume (SCF) at working pressure, which you'll want to confirm with the seller along with the specific gas factor for this cylinder.

What is the requalification or inspection status?

The tank was manufactured in 2014 and carries certification good through 10/2034. DOT Type 1 CNG cylinders typically require requalification every 3 or 5 years depending on service and DOT exemptions; confirm with the seller when the last inspection was performed and whether the 2034 date reflects the 15-year service life or a recent requalification interval.

What should I inspect before putting it into service?

Inspect the exterior for corrosion, dents, gouges, or arc strikes, and verify the Sherwood valves cycle freely without leaks. Check the brass thermal PRD for corrosion or damage, confirm all manufacturer stampings and DOT markings are legible, and verify the cylinder has not been exposed to fire or overpressure (look for discoloration or distortion). Hydrostatic testing may be required depending on time since last requalification and your application's regulatory requirements.
