For over 30 years, Superior Tank Co., Inc. (STCI) has designed, manufactured, installed and serviced bolted tanks and welded tanks for oil storage.
STCI is one of the only bolted steel manufacturers which can proudly display the prestigious American Petroleum Institute (API) SPEC 12B monogram on our bolted tanks for oil storage. In order for a bolted tank to include the API 12B monogram, the storage tank must strictly adhere to the API SPEC 12B standards. In addition, the tank manufacturer must be recertified on an annual basis to meet the strict API SPEC Q1/ISO 9001:2008 quality standards.

All STCI bolted tanks for oil storage are engineered and manufactured to meet the strict API SPEC 12B design standard and include numerous elements to increase tank durability and longevity. To seal our tanks, we use heavy duty gaskets made of Buna-N or Viton in place of mastic putty which is incompatible with oil storage. Our custom made Buna-N and Viton gaskets are extremely durable and resistant to crude oil and other corrosive liquids. Also, to increase the lifespan of the bolted tank, our gaskets have high tensile strength to prevent tearing and remain flexible over time. In addition, our gaskets do not require routine replacement thereby decreasing maintenance requirements. To reduce service intervals, our bolted tanks feature premium Scotchkote powder coating which is specifically formulated for oil storage. Our API SPEC 12B bolted tanks range in capacity from 100 to 10,000 bbls and adhere to dimensions determined by the API SPEC 12B specification.

Every year, we sell hundreds of parts for bolted tanks and welded steel tanks. Even though many ground storage tanks needing parts were not originally manufactured by Superior Tank Co., Inc., we can provide standard replacement components for steel storage tanks or can fabricate custom parts and accessories to fit.

Over the last 32+ years, we have discovered there are five storage tank elements which are key to ensuring your water and oil storage tanks achieve their maximum lifespan:

1 Ground storage tank bottoms
2 Roof rafters
3 Ladders and safety railings
4 Hardware, gaskets and appurtenances
5 Powder coating touch up kits

While these seem to be the fundamental oil and water storage tank components, we have found many ground tanks in the field require one of more of these items.

For example, it is not unusual for welded steel tanks to experience bottom corrosion and subsequent steel loss as the underside cannot be coated. In addition, select hot dipped galvanized bolted tanks which are over 30 years old can experience bottom corrosion and require new components. Our fabrication department will custom manufacture replacement steel tank bottom sections to any size or dimensions to fit either bolted tanks or welded steel tanks.

Superior Tank Company., Inc (STCI) is one of the only manufacturers of bolted steel oil storage tanks which can feature the prestigious API SPEC 12B monogram. In order for the bolted steel tank to include the API 12B monogram, the tank must strictly adhere to the API SPEC 12B standards.

Our bolted steel tanks for oil storage are engineered to meet the strict API SPEC 12B design standard and include numerous elements to increase tank durability and longevity. To seal our tanks, STCI utilizes Buna-N or Viton gaskets in place of mastic putty which cannot be used for oil storage. The Buna-N and Viton gaskets are extremely durable and resistant to crude oil and other petrochemicals. In addition, the gaskets have a high tensile strength to prevent tearing and they remain flexible over time, thus eliminating leaks. For increased durability, we apply factory powder coating specifically formulated for oil storage. For continuous immersion service, epoxy factory powder coating or premium Scotchkote powder coating is applied to tank interiors. TGIC polyester powder coating is used on the exterior of our bolted steel tanks for greater UV resistance. API approved appurtenances such as specialized roof vents, gas outlets, liquid outlets and manways are used on all steel tanks for oil storage. Superior Tank Co., Inc. can also fabricate custom internal and external piping to meet customer requirements.
