Dixie Southern designs and completes custom chemical tank fabrication. Our above-ground, welded-steel storage tanks meet the exacting standards of the American Petroleum Institute (API).
API establishes standards for the design and fabrication of welded-steel storage tanks. Carbon steel and stainless-steel tanks are often used for storing oil and other liquids. The API standard is applicable for stationary atmospheric and low-pressure petroleum storage tanks used in all sectors of the petroleum and petrochemical industry. We serve customers in the oil and gas industry, and beyond, for their custom, legal load or over-dimensional, API certified storage tanks in carbon steel and stainless-steel tanks.
Some examples of API shop fabricated tanks we design and fabricate:
- Flocculation tanks
- Separator tanks
- Petroleum storage tanks
- Chemical storage tanks
- Storage tanks
- Sulfuric acid storage tanks
- Bulk tanks
- Caustic tanks
- Caustic storage tanks

- Oily water tanks
- Sulfuric acid tanks
- Stainless steel tanks
- Carbon steel tanks
Dixie Southern has decades of experience designing, fabricating, assembling, and inspecting API 620 and API 650 storage tanks. At our 12-acre, 65,000 square foot manufacturing facility in West Central Florida, we have the professional designers, welders, and fabricators needed to build your custom welded API storage tanks.
API 620 Tanks
The design configuration of API 620 requires that the user has an elevated or flat bottom on which to set the stainless-steel tank. This type of storage tank has a single, vertical, central axis of revolution, and the tank is used for products that have high internal pressures, such as liquified natural gas and cryogenic tanks. Available as a stainless-steel tank or carbon steel tank.
API 650 Tanks
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 oil industry. Available as a stainless-steel tank or carbon steel tank.
Our API Tanks are designed, fabricated, and delivered to your facility worldwide.

DIMENSIONS
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).
