Have you seen those tanks used in non-refrigerated service? How about those tanks that are well-supported in the bottom? Those tanks are based on the API 650 design by the American Petroleum Institute (or API).
Here are some facts about the design of API 650 tanks:
- Their main advantage is they come in almost any size, making them ideal for storing chemicals, gas, biofuel, oil, and water. Thanks to this, they are among the oil industry’s most commonly used tanks.
- Their design uses two units (systems). One is the SI Units (or the International Standard) and the other is the US Customary Units.
- They are made with special considerations as a basis. Their design gives allowance for corrosion. The API 650 tanks’ main foundation should also have tolerance for the levelness of secondary foundations.
- Different designs for their roofing system are allowed. Some of the common roof designs are dome, umbrella, and fixed roof. You can also find that their roofing systems give support to the plates and the whole structure.
- The main material used for construction should be chosen carefully. Particularly, the metal should be capable of lasting well in rough temperatures. They should not be easily destroyed upon exposure to temperatures around 15 degrees Fahrenheit.
- The API follows a foot by foot method for the measurements of standard tank sizes. As this method says, API 650 tank designs should have an estimated total weight (empty tank) of 354,980 lbs.
- They can last well in conditions with high temperatures and low pressure. They can store content in an environment of 40F up to 500F. They can also store contents at lower pressure (2 1/2 PSI max).
If you compare them to others, storage tanks under API 650 stand out. They are highly functional, and they offer lots of advantages.
