WINBCO ensures decades of longevity with our durable API 650 oil storage tanks delivered online, on time, every time.

What is an API 650 tank?

API 650 tanks are built and tested to design standards identified by the American Petroleum Institute (API) for the construction of above-ground welded tanks for oil storage. The code regulates the construction of atmospheric tanks up to 2.5 psig and 500°F with the option of flat or sloped bottoms and cone or dome roofs.

Though API 650s set the standard for oil storage tanks, they’re also commonly used to safely store chemicals, gas, water and biofuels in low-pressure conditions. WINBCO’s highly trained team of oil storage tank manufacturers completes shop-assembled projects in our 80,000+ square feet facility located in Iowa, the heart of the biofuels industry and a central location to ship tanks from coast to coast. We can also travel for field-erected assignments if the scope of the project requires on-site construction.

WINBCO’s Custom-Manufactured API 650 Oil Storage Tanks

While the WINBCO team strictly follows regulations outlined by the API 650 standard, we have the expertise and experience in the industry to custom-build oil storage tanks and process tanks to your specifications while remaining compliant. We’ll work with you to decide on custom specs like diameter, height, construction material, internal and external design pressure, design temperature, design-specific gravity, tank support (self-supported cones or internally supportive columns) and more. We specialize in stainless steel fabrication to provide the maximum product lifespan and quality but also work with carbon steel and other alloys as requested.

Our welded tanks for oil storage are built using WINBCO’s innovative technology and automated welding equipment developed in-house for superior quality, performance and finish. We guarantee no scratching on final products, 100% penetration welding to X-ray standards and a tighter, finer finish no other manufacturer on the market can live up to. As a result, WINBCO’s oil storage tanks and process vessels are dependable and cost-effective, with few maintenance needs and uninterrupted performance for decades of uptime and lower total cost of ownership over the lifespan.

For shop-assembled fabrication, we can custom-build API 650 tanks for a variety of purposes up to 14 feet in diameter and 150 feet tall. Anything outside of those parameters is eagerly handled by our field erection team who build our vessels on site to meet your specifications. API 650 tanks are typically used for liquid storage, but we can design a custom tank to meet your needs, including food-grade finishes if applicable. Examples of our wide variety of API 650 tanks include, but are not limited to:

  • Stillage tanks
  • Storage tanks
  • Fermenters
  • Beer wells
  • Equalization tanks
  • Liquefaction tanks
  • UASB reactors
  • Slurry tanks
