One of the first questions we are asked is “how much does a bolted steel tank cost”? Unfortunately, the answer is a little complex as the price of a bolted tank is impacted by a variety of factors. Elements include storage tank design specification, relevant local building codes, quality of raw materials, scope of work included in the contract, manufacturer experience and tank installation team skills/training.
The various design specifications such as AWWA D103, NFPA 22 and API 12B determine tank appurtenances, shell design, steel thickness and even tank size in some cases. For example, the American Water Works Association (AWWA) D103 standard applies to all bolted tanks used for potable water storage and mandates the interior epoxy coating is NSF 61 certified. Bolted tanks for fire protection need to comply with the National Fire Protection Association (NFPA) 22 standards which requires specific tank components such as tank heating systems when needed and reinforced concrete ringwall foundation. When a bolted tank is used for oil storage, the American Petroleum Institute (API) 12B standard is commonly used as a reference but tanks do not have to comply. However, for customers desiring a guaranteed level of quality, the API 12B monogram program ensures the tank meets very specific design criteria and the bolted tank manufacturer is API Spec Q1 / ISO 9001:2008 certified.Read More “How Much Does A Bolted Steel Tank Cost?”
