API flanges refer to flanges that meet the standards set by the American Petroleum Institute (API). These flanges are typically used in applications related to the oil and gas industry, including pipelines, refineries, and petrochemical plants.

API flanges come in various sizes and pressure ratings, and are available in different materials such as carbon steel, stainless steel, and alloy steel. The most commonly used API flanges are the API 6A and API 16A flanges.

API 6A flanges are used for wellhead and Christmas tree equipment, while API 16A flanges are used for blowout preventers (BOPs) and their associated equipment. These flanges are designed to withstand high pressure and temperature conditions, and are subject to rigorous testing and certification procedures to ensure their safety and reliability.

API flanges are typically connected using bolts and nuts, and the sealing surfaces are usually machined to ensure a tight and leak-free connection. Proper installation and maintenance of API flanges are crucial to ensure their performance and safety in high-pressure applications.
