What standard is the primary reference for Fitness-for-Service (FFS) assessments referenced in API 510?

Accepted Answer

API 579-1/ASME FFS-1

Answer

API 579-1/ASME FFS-1 is the joint API/ASME standard specifically developed for Fitness-for-Service assessments of in-service pressure equipment.

Question 2

How many levels of Fitness-for-Service assessment are defined in API 579-1/ASME FFS-1?

Accepted Answer

Three levels: Level 1, Level 2, and Level 3

Answer

API 579-1/ASME FFS-1 defines three levels of assessment ranging from conservative screening (Level 1) to specialized engineering analysis (Level 3).

Accepted Answer

To evaluate whether equipment with a flaw or damage can continue to operate safely

Answer

FFS assessments evaluate whether in-service equipment containing flaws or degradation can continue to safely operate at defined conditions.

Question 4

What is the Remaining Strength Factor (RSF) as used in API 579-1/ASME FFS-1?

Accepted Answer

The ratio of the damaged component's failure strength to the undamaged component's failure strength

Answer

The RSF quantifies structural integrity by comparing the failure load of the damaged component to that of the same component without damage.

Question 5

What is the default minimum allowable Remaining Strength Factor (RSFa) specified in API 579-1/ASME FFS-1?

Accepted Answer

0.90

Answer

The default RSFa in API 579-1/ASME FFS-1 is 0.90, meaning the damaged component must retain at least 90% of the undamaged component's failure strength.
