Steel storage tanks are everywhere in the US. They store everything from water to gasoline. However, not all tanks are the same. There are rules and regulations for each type, depending on what they contain. For tanks that store petroleum products, it has to follow the rules under API 653. If you want a tank reconstruction so you can store gasoline, you need to know the regulations.
API stands for American Petroleum Institute. API 653 is the standard for steel tanks used to store gasoline and petroleum products. Because these are dangerous and toxic liquids, it is important for the safety of people and the environment to make sure that storage tanks are in good condition. Service providers such as Heartland Tank Services can be of great help in this regard. It is an improvement of the old standard API 650, which replaced API 12C. However, API 650 is still around. If there are differences between the two standards, API 653 rules apply.
API 653 inspectors check on all tanks in active service. They make sure that the tanks have no leaks or weak spots that can lead to problems, such as bursting at the seams. They also approve plans to repair, modify, move, and reconstruct storage tanks. They check the bottom, top, shell, and foundation of the tank. Inspectors also test the nozzles and other stuff attached to the tank. If the tank does not fill the minimum requirements, it is not certified.
API 653 applies only to organizations that have their own engineers and technical staff to do any work on the tank. The inspector is part of API to make sure that the work is correct. The rules do not cover everything, however. Anything not detailed in API 653 should observe what is in API 650.
Using a steel tank to store flammable or toxic chemicals is risky. However, if the tank owner follows the API 653 standard, there should be fewer problems. The API website has the latest version of the API 653 guidelines.
