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.
API and ASME formed a joint committee to produce a single FFS Standard that can be used for pressure-containing equipment. This standard, released in 2007, 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
3-Day Introductory Course
An introduction to API 579-1/ASME FFS-1 is provided to first time users. This class covers all assessment levels and is primarily intended for engineers or inspectors who perform pressure vessel calculations. Attendees should have a working knowledge of equipment design codes and standards, and basic stress calculations.
- A. Overview and Opportunities for FFS
- B. Introduction to API 579-1/ASME FFS-1
- C. FFS Assessment Procedures
- D. Damage Mechanisms Overview
- E. 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 and Remaining Life
- - Fire Damage
- - Dents, Gouges and Dent-Gouge Combinations
- - Laminations
- F. In-Service Margins/Validation
The instructors will discuss the background and logic behind the assessment procedures and intersperse some example problems. However, due to the scope of the API 579 Standard, detailed example problem solving practice and explanation will be the focus of the additional 1-day Equity Engineering example problem course. In addition, other highlights include:
- Discussion of damage mechanisms and the importance of identification.
- Various detailed inspection techniques for damage mechanisms, with focus on flaw characterization.
- Overview of remaining life assessment, remediation, and methods to extend the life of damaged equipment.
- Presentation of practical examples of FFS procedures.
- Details on how to assess damage/flaws that are not directly covered in API 579-1/ASME FFS-1.
- Interaction of API 579-1/ASME FFS-1 with API Publications 510 and 570, API 653, and NBIC NB-23.
- Relationship of API 579-1/ASME FFS-1 with other international FFS standards.
- Future directions of API 579-1/ASME FFS-1.
1–Day API 579 Problem Solving Course (Equity Engineering)
The time does not allow for a detailed example problem working sessions during the API course. Therefore, an additional day has been added to provide the instructors/attendees a chance to review example problems in depth. The instructors will guide the students through the API 579-2/ASME FFS-2 Example Problem Manual and discuss the procedures and solutions in detail. Typical problems solved during the session include brittle fracture, general and local metal loss, pitting, crack-like flaws and creep.
Equity’s VCESage FFS Software will be used to demonstrate additional problems.
API does not endorse this 1-day course or the software that Equity uses. Students can register for only the API course and are not required to take the 1-day example problem course.
Who Should Attend
Plant engineers in mechanical reliability programs, plant inspectors, central engineering staff and consultants 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
