Fitness for Services (FFS)

Fitness-for-service (FFS) evaluations are performed on pressure equipment to check for various types of flaws.

Process industry and manufacturers often need to be able to track the readiness and structural integrity of their equipment in order to ensure that it is functioning optimally and that there is no risk of sudden, unexpected breakdowns.

Our solution

VELOSI performs fitness-for-service evaluations on pressure vessels, heat exchangers, boilers, storage tanks, piping and other specialized equipment in order to ensure the structural integrity of equipment for the intended design parameters, which are usually level 1, 2 and 3. These evaluations are based on API-579-1 /ASME FFS-1, (fitness-for-service) and other applicable codes, standards and specifications.

VELOSI has evaluated all types of damage that can occur in the refining and petrochemical industries on a wide variety of pressure vessels, process piping, transmission pipelines, storage tanks, heat exchangers, heaters (casing, tubes and stacks) and mechanical components of specialized equipment.


FFS is useful for manufacturers who are concerned about unexpected down time and equipment failure. By conducting this type of evaluation, problems can be pre-empted and dealt with quickly and effectively.
