API 650 and 12C Field Storage Tanks Should Follow This API Standard to Ensure Safety and Efficiency

Storage Tanks Considering using oil storage tanks for your company? It’s a good choice if you know what you’re getting into. Here’s what you need to know about the API 653 requirements.

What is the API 653?

In January 1991, the American Petroleum Institute (API) published the first edition of the “Tank Inspection, Repair, Alteration, and Reconstruction” also known as the API Standard 653. It is a formal standardization manual that discusses the requirements for the reconstruction, alteration, repair, and inspection of steel tanks used to store petroleum and chemicals.

The requirements in API cover above ground storage tanks that are made of steel and were built based on the API 12C (1st published in 1936) and API 650 (1st published in 1961) standards. It provides minimum requirements for two main purposes: for integrity and maintenance of storage tanks.

Minimum requirements for the API 653 maintain the integrity of used above ground storage tanks that are refrigerated or non-refrigerated, riveted or welded, and with atmospheric pressure. It specifically applies to the nozzles, attached appurtenances, roof, structure, shell, bottom, and foundation of the first welding-end, first threaded joint, or first flange connection of the tank.

Why You Should Use It

API 653 can also be applied in the inspection and relocation of existing API 12C and API 650 storage tanks. This raises the question: why should it be used to make sure that existing API 12C and API 650 storage tanks are safe to use?

According to API, ignoring 653 can result in technical, maintenance, and operational problems later on. There are three other reasons: First, API 653 can make your tanks engineered for safety. It is based on principles guided by expert engineers in constructing safe storage tanks for highly volatile liquid. Second, its standards are accepted both internationally and in all states in the U.S. Established in 1919, API is the reliable, credible, and the only source of industry standards in oil and natural gas. You can never go wrong with the standards they recommend. Third, the API 653 requirements put into consideration the rights of consumers to a correctly built field storage tank.

Finding the right storage tanks for oil and natural gas is easy, and dangerous, if you don’t follow industry standards. Learn about API 653 and how it can ensure safety for your oil storage tanks.
