BechtFFS Software Package

BechtFFS main screen

BechtFFS is an API 579-1/ASME FFS-1 compliant, web-based software application designed to assist operators/owners in evaluating equipment items which have developed defects in service. The quantitative calculations performed in BechtFFS assess the structural integrity of the flawed component and ultimately provide a recommendation whether the component should be taken out of service and retired or repaired, or is fit for continued service.

  • Immediate access from any internet-enabled device
  • Developed by leading industry FFS experts
  • User-friendly format with online Help Manual & Video Training
  • Free 30-Day Trial

ffsmainpicBecht Engineering has extensive experience and expertise in the field of Fitness-For-Service. We have performed evaluations for all of the damage mechanisms covered in ASME FFS-1/API 579 for clients around the world. We have performed Fitness-For-Service evaluations on piping, pressure vessels, heat exchangers and tanks. Our wealth of knowledge and experience enables us to provide authoritative, practical, knowledge based answers, and to solve your problems. We have performed fitness for service assessments on more than 2,000 pressure vessels.

We are organized to quickly and efficiently handle all levels of Fitness-For-Service assessments including rapid response to emergency situations where quick assessments are required to keep a plant running or when damage is found as part of discovery during turnarounds, and rapid assessments are necessary to determine the path forward. For immediate response, contact our FFS coordinator, Magnus Gustafsson at 571-550-0722 or click on the urgent request button on this page. The request will go to Mr. Gustafsson, as well as our President, Dr. Charles Becht and General Manager, John Basil.

Our knowledge comes from active participation in the new construction codes for equipment such as pressure vessels and piping as well as post construction standards. Magnus Gustafsson is a member, Gerrit Buchheim has been a member since inception and is taskgroup chair for Part 7 Hydrogen Blistering/HIC/SOHIC, Jim McLaughlin is a contributing member, Bob Sims is a member and the past vice-chair and George Antaki is past vice-chair of ASME FFS-1/API 579. Dr. Charles Becht IV is the founder and immediate past-chair of ASME PCC-2: Repair of Pressure Equipment and Piping and member and past chair of the ASME Post Construction Committee. When required, we design the repairs to restore the equipment integrity.


Request Info on Fitness for Service

Metallurgical and Corrosion

Becht staff include over ten senior materials experts with expertise in applications including power, refinining, petrochemical and chemical facilities, and materials including metals, coatings and linings, and nonmetals such as refractories, thermoplastics (e.g. high density polyethylene) and reinforced thermosetting resins (e.g. fiberglass).  Our services include material selection, establishing operating envelopes for equipment, failure analysis, remaining life assessment, and establishing deterioration mechanisms and their associated probabilities for risk based inspection and development of equipment reliability plans.  We are experts in modifications to existing chemical processes to alleviate and control corrosion that allows continued operation of existing equipment.  We are experts in the equipment requirements for processing corrosive crudes (e.g. high TAN crudes such as Doba crude) as well as material applications for high temperature services such as steam cracking furnaces and furnaces to produce synthesis gas.

Multi-Discipline Team

Becht Engineering has experts in Codes and Standards, Stress Analysis, Materials, Corrosion, Fracture Mechanics, Vibration, Fluid Flow, Hydraulics, Inspection and Testing to draw upon in performing the Fitness-For-Service assessment.  Most damage mechanisms do not act in isolation, and our multi-disciplined approach has successfully solved some of the most challenging problems.


Occasionally, the Fitness-For-Service assessment will indicate that suitable margins against failure are not achieved.  One recourse is to re-rate the equipment.  Becht Engineering has substantial experience and expertise in re-rating equipment; skills that we can use in this outcome of a Fitness-For-Service assessment.  As members of ASME Boiler and Pressure Vessel as well as ASME B31 Piping code committees, we are experts in the application of code rules.   Re-rating equipment may allow it to be safely operated until the damage can be repaired or a replacement can be fabricated.


Sometimes, the appropriate course of action for in-service damage is to execute a repair.  From our wealth of knowledge based in our leadership in the development of ASME PCC-2: Repair of Pressure Equipment and Piping, we can recommend an effective and functional repair for most in-service damage mechanisms.  We even have welding experts with over 50 years of experience who can provide welding procedures for the most complex welding repairs.

Vibration Assessment and Correction

Becht Engineering evaluates piping, vessel, heat exchanger, fired heater, stack and other equipment and structural vibration and vibration failures and develops corrective actions. Our tools range from simple screening criteria to sophisticated finite element and piping dynamic analyses. We provide detailed designs that correct the vibration conditions. We also measure the levels of vibration in the field with sophisticated data acquisition equipment. Dr. Becht and Don Frikken teach a course on Practical Piping Vibration.


Becht staff includes materials and mechanical engineers with expertise in welding and fabrication of pressure equipment. This includes expertise in heavy wall vessels, welding in difficult circumstances such as the weld repair of embrittled material, and welding of modified 9 chrome steel. In addition, we have designed and evaluated heat treatment plans such as bulls-eye heat treatment for coke drum repairs and heat treatment of new nuclear heat exchangers. This expertise is applied both for new construction and repair.
