API 620 Tanks

The design configuration of API 620 requires that the user has an elevated or flat bottom on which to set the steel tank. This type of storage tank has a single, vertical, central axis of revolution, and can store contents at slightly higher pressures and lower temperatures than API 650. Available as a stainless-steel tank or carbon steel tank.

The design configuration of API 650 covers tanks that support the whole bottom evenly and tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. API 650 tanks can store oil, gas, chemical, water, and biofuel and are some of the most common steel tanks in the industrial markets. Available as a stainless-steel tank or carbon steel tank.

API Tanks are inspected in accordance with the appropriate API standard and the corresponding label is attached.


Your API shop fabricated tank is delivered to your facility anywhere in the continental U.S.


We manufacture API tanks of various shapes and sizes to accommodate different capacities and applications. Diameters for API tanks can range from 36″ to 192″.

36″ diameter tanks: Capacity up to 10,000 gallons (typically store smaller quantities of materials, such as on a drilling rig or at a small-scale production facility).

48″ diameter tanks: Capacity up to 25,000 gallons (commonly used in small to medium-scale industrial applications).

72″ diameter tanks: Capacity up to 60,000 gallons (suitable for larger industrial applications).

96″ diameter tanks: Capacity up to 120,000 gallons (typically used in large-scale industrial applications).

120″ diameter tanks: Capacity up to 220,000 gallons (commonly used to store petroleum or other chemicals).

144″ diameter tanks: Capacity up to 320,000 gallons (suitable for larger-scale petroleum storage applications).

192″ diameter tanks: Capacity up to 500,000 gallons (often used to store petroleum or other liquids in large-scale industrial facilities).
