What is the difference between API 620 and API 650 Storage Tanks?

Both API 620 and API 650 Storage Tanks can be shop fabricated or field erected depending upon your site and project’s requirements.

In general, API 650 tanks are ideal when you need large capacity, lower pressure or ambient-moderate temperature storage. API 650 is often more cost-effective and often, but not always, comes in a vertical cylindrical design.

Feature	API 620	API 650
Pressure Rating	Higher (<= 15 PSI)	Lower (<= 2.5 PSI)
Temperature Range	Low-temperature (<= 250 ˚F)	Ambient to moderate (<= 500 ˚F)
Vacuum Range	<= 1 PSI	<= 1 PSI
Size & Shape	Customizable shapes & sizes	Predominantly vertical cylindrical
Common Applications	Cryogenic, chemical storage, etc	Chemical, Oil, water, bulk storage, etc
