Most states require regular inspections of ASTs to ensure their integrity to safely hold the contents. API 650 also addresses how best a tank can be constructed to withstand natural conditions such as earthquakes and high winds.ĪPI 653 is the standard for the inspection and repair of ASTs as built to the API 650 standard. The API Specifications address the required thickness of each piece of steel based on the size of the tank being built as well as the welding requirements.

The main API specifications that are the recognized standard for large field-welded steel ASTs are API 650 for construction and API 653 for tank inspection.ĪPI 650 is the internally recognized standard for the construction and maintenance of AST units. Even if an above ground storage tank is not regulated by law, the American Petroleum Institute (API) provides standards that provide guidance as to sound engineering for the manufacturing, use, maintenance, and inspection of these tanks. Depending on the type of substance stored in the tank, ASTs may be regulated by the federal or state government.
