It discusses procedures for performing proper fitness-for-service evaluations and ensuring the safe and reliable operation of older plants and existing facilities. This standard contains numerous sections on assessment procedures for calculating the impact of damage mechanisms such as brittle fracture and general or local metal loss.

API 579 is a complex document covering several different types of equipment that may contain flaws or damage. When performed correctly, the assessments laid out in this standard can provide information on the current state of damage, as well as offer an estimate for the projected remaining life.
