FFS Helps Make Decisions to Run, Repair or Replace
The American Petroleum Institute (API) conducts training classes that can help you understand and use the techniques Fitness-For-Service Assessments of pressurized equipment including pressure vessels, piping, and tankage. The ASME and API design 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 typically do not provide assessment procedures to evaluate degradation due to in-service environmentally-induced damage or from original fabrication that may be found during subsequent inspections.
Fitness-For-Service (FFS) assessments are engineering evaluations that are performed to demonstrate the structural integrity of an in-service component containing a flaw or damage. The first edition of API 579 was developed to provide guidance for conducting FFS assessments of flaws commonly encountered in the refining and petrochemical industry that occur in pressure vessels, piping, and tankage. However, the assessment procedures have been used to evaluate flaws encountered in other industries such as the pulp and paper industry, fossil electric power industry, and nuclear industry.
New Joint API and ASME FFS Standard Released July, 2007
API and ASME formed a joint committee to produce a single FFS Standard that can be used for pressure-containing equipment. This standard is known as API 579-1/ASME FFS-1. The new joint standard includes all topics contained in the 2000 Edition of API 579 and includes new parts covering FFS assessment procedures that address the unique damage mechanisms experienced by other industries such as the fossil electric power industry and the pulp and paper industry.
API 579-1/ASME FFS-1 for State-of-the-Art FFS Assessments
The FFS methods in API 579-1/ASME FFS-1 are quantitative engineering evaluations that demonstrate the structural integrity of an in-service component that is flawed or damaged. The procedures, which are specifically prepared for equipment in the refining and chemical process industries, can be used to make run-repair-replace decisions. This is needed to ensure the safe operation of pressurized equipment that may have flaws or damage identified through inspection.
FFS procedures enable users to assess the integrity of equipment and make projections about its remaining useful life. The course teaches evaluation methods for general and localized corrosion, widespread and localized pitting, blisters, laminations, weld misalignment, shell distortions, and environmental cracking. Attendees also learn assessment methods for brittle fractures, long-term creep, and fire damage.
If the results of an FFS assessment indicate that a certain equipment component is suitable for current operating conditions, it can continue to be operated at these conditions if appropriate monitoring and inspection programs are established. If the results of the FFS assessment indicate that the equipment is not suitable for current operations, API 579-1/ASME FFS-1 provides calculations that can be used to re-rate the component.
For pressurized components (e.g. pressure vessels and piping), these assessments can be used to find a reduced maximum allowable working pressure and/or coincident temperature. For tank components (shell courses), the calculations can be applied to determine a reduced maximum fill height.
The methods and procedures in API 579-1/ASME FFS-1 are intended to supplement the rules in API 510, 570, and 653 and other Inspection Codes. The procedures in API 579-1/ASME FFS-1 can be used for FFS assessments and/or re-rating of components that are designed to the following codes:
- ASME B&PV Code Sec. VIII Div. 1
- ASME B&PV Code Sec. VIII Div. 2
- ASME B&PV Code Section 1
- ASME Piping Codes (B31.3/B31.1)
- API 650 and API 620
- Other international codes and internal corporate standards
An introduction to API 579-1/ASME FFS-1 is provided to first time users. This class covers inspection rules for all levels of assessments with a focus on Level 1 assessments. This course is primarily intended for inspectors who inspect pressure vessel and may perform Level 1 calculations. Attendees should have a working knowledge of equipment design codes and standards, and code calculations. The Course Outline is shown below:
- A. Overview of FFS
- B. Introduction to API 579-1/ASME FFS-1
- C. FFS Assessment Procedures
- D. Assessment of Equipment for:
- - Brittle fracture
- - General Metal Loss
- - Local Metal Loss
- - Pitting Corrosion
- - HIC, SOHIC and Hydrogen Blister Damage
- - Weld Misalignment and Shell Distortions
- - Crack-Like Flaws
- - Creep Damage
- - Fire Damage
Some Level 1 assessment example problems are discussed in the course. However, due to the scope of the API 579 Standard, detailed example problem solving practice and explanation are not the focus of this course.
The instructors, who are also the principal contributors to API 579 and API 579-1/ASME FFS-1, will discuss the background behind the assessment procedures and intersperse some example problems. In addition, other highlights include:
- - Various detailed inspection techniques for damage mechanisms, with focus on flaw characterization.
- - Presentation of practical examples of FFS procedures.
- - Interaction of API 579-1/ASME FFS-1 with API Publications 510 and 570, API 653, and NBIC NB-23.
- - Overview of how to assess damage/flaws that are not directly covered in API 579-1/ASME FFS-1.
Who Should Attend
Plant inspectors for refining and petrochemicals.
Training in API 579-1/ASME FFS-1 can also be beneficial for the fossil fuel utility, pulp and paper, nuclear energy, and other industries that use and maintain pressurized equipment.back to top
The course fee does not include a copy of API 579-1/ASME FFS-1 Fitness-For-Service. It is suggested that all students have a copy of the latest edition during the course.
