STAINLESS STEEL BOLTED & UNCOATED TANKS

As another storage tank alternative, Superior Tank offers 304 and 316 stainless steel storage tanks in both a bolted and welded tank design. Our stainless steel storage tanks are a great option for numerous applications and are designed to securely hold both very corrosive and non-corrosive liquids in a clean and sanitary manner.

Stainless steel bolted storage tanks are used in industries such as food processing, agriculture and chemical storage as the stainless steel does not react with the tank contents.

We offer stainless steel bolted tanks in a wide range of capacities and configurations to meet the project requirements. In addition to stainless steel liquid storage tanks we can also design stainless steel storage silos. For select applications, we can also provide tanks without coating. Please ask your sales representative for details.

304 VS. 316

Superior Tank aims to provide its customers with a range of options to meet the diverse needs of each project. When it comes to offering Stainless Steel bolted tanks, we have the capability to offer both 304 and 316 Stainless Steel. Both steel grades are comparable in appearance, chemical makeup and general characteristics. Each type of steel is naturally resistant to corrosion, highlighting the fact that neither requires a special coating or finish. Conversely, both types of steel serve a different purpose when it comes to the storage of specific liquids and material. Below are general differences in characteristics and applications:

304 Stainless Steel

  • More versatile and widely used
  • Less Expensive then 316
  • Better with milder acids & less salt exposure
  • Contains more Chromium

316 Stainless Steel

  • Superior corrosion resistance
  • Better with powerful corrosives, chlorides and salt exposure
  • Expensive
  • Longer Lasting
  • Contains of Molybdenum: a chemical element used for the strengthening and hardening of steel

ALUMINUM BOLTED TANKS

For specific projects, Superior Tank manufactures aluminum bolted steel tanks. These custom engineered tanks are for specialty applications such as oil storage and storage of extremely corrosive liquids. Our aluminum tanks are also used for sanitary storage of foods and beverages.
