Tanks play an important role in the storage of various liquid materials and products. The oil and natural gas industry, for example, relies on different types of tanks to keep their products safe and in optimal condition during processing and storage.
The American Petroleum Institute (API) is a key name in the industry; they set the standards, which are used and adapted by various oil and petroleum companies worldwide.
API put in place stringent standards in the manufacture of storage tanks. They help ensure quality in each tank – from design and manufacture to erection and maintenance.
Among API’s various standards, API 650 is one of the more popular. Many industrial tanks used today are built according to this golden standard. API 650 Standard tanks are commonly used as containers of oil, gasoline, and various types of chemicals. They are designed and built to store special types of liquid. This is why many production facilities and refineries rely on them.
API requires high-quality materials in the manufacture of 650 tanks. These materials include carbon steel, austenitic stainless steel, duplex stainless steel, and other hardwearing metals. These tanks must also have a ground-supported bottom, as required by API.
API 620 is another popular standard in the industry. It covers the design and manufacture of large welded steel tanks used for storing products requiring high internal pressure. API 620 tanks have a single, centered, vertical axis of revolution, making it different from other tanks. They are designed particularly for operation at 250 degrees Fahrenheit or below.
They are also made of a combination of metals such as carbon steel, austenitic stainless steel, and nickel alloy. The standard requires an elevated or flat bottom on which to place the tank.
