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. Read More “Complete Solutions for Oil Storage Tanks”
