Fitness for service evaluations determine whether equipment with existing flaws (such as distortions or cracks) found by inspection is suitable for continued service.
Codes and standards for pressurized equipment provide rules for the design, fabrication, inspection, and testing of new pressure vessels, piping systems, and storage tanks. These Codes do not address the fact that such equipment may degrade while in service, and that deficiencies due to degradation, or original fabrication defects may be found during subsequent inspections of in-service components.
We provide Fitness-For-Service (FFS) evaluations to demonstrate the structural integrity of such equipment.
Our evaluations, based on API-579 and other Codes and Standards, are used to make run/repair/replace
decisions. These evaluations ensure that pressurized equipment containing
flaws which have been identified by inspection can continue to operate.
Such evaluations include components designed and constructed to the following
codes:
- ASME B&PV Code, Section VIII, Division 2
- ASME B&PV Code, Section VIII, Division 1
- ASME B&PV Code, Section 1
- ASME B&PV 31.3
- ASME B&PV 31.1
- API 650
- API 620
Fitness for Service evaluations often result in lower maintenance & operating costs as well as improved plant safety.
