API 579 Insights

What is API 579?

API 579, also known as Fitness-For-Service (FFS), is an assessment procedure published by the American Petroleum Institute (API) for evaluating the structural integrity of in-service equipment. It provides methodologies for evaluating flaws and damage mechanisms in pressure vessels, piping, and storage tanks to determine if they are fit for continued service. It is commonly used in the petrochemical and refining industries to make run/repair/replace decisions based on engineering principles, optimizing safety and minimizing downtime.
