The oil and natural gas industry relies on high-quality equipment to ensure safe and efficient transfer and storage of their products. The American Petroleum Institute, for instance, is one of the biggest names in the manufacture of such equipment. For many years, they have served a vital role in the industry, thanks to their tanks and storage products.
API is more than just a manufacturer and supplier of tanks and equipment to some of the biggest oil and natural gas companies in the country. The association is also well respected in the industry for providing guidelines and standards. In fact, they maintain an inventory consisting of over 600 standards and recommended industry practices.
The association imposes stringent measures and standards in operations involving above ground industrial steel storage tanks. Their comprehensive standards include everything from design and fabrication to the erection of tanks.
API 650 is one of most popularly used standards. Many manufacturers follow these standards to deliver high-quality industrial tanks. API 650 tanks are used as storage equipment for oil, gasoline, chemicals, and produced water. Most production facilities and refineries rely on these tanks for safe and efficient storing of their materials and products.
Based on the standards, the tanks must have a ground-supported bottom, with its roof either open or closed. They are made from a variety of metals including carbon steel, aluminum, austenitic stainless steel, and duplex stainless steel.
API 620 is the standard covering the design and construction process of large welded steel tanks. API 620 tanks are low-pressure tanks and are designed to work at 250 degrees Fahrenheit or lower. Another distinguishing feature is their single, centered, vertical axis of revolution.
These tanks are used to store products that demand high internal pressure, such as in the case of LNG and cryogenic tanks. Materials used for API 620 tanks include carbon steel, nickel alloy, and austenitic stainless steel.
These are only two of the commonly used API standards in the industry. By abiding by these standards, manufacturers and service providers are able to provide high-quality storage equipment and related services to oil and gas companies.
