At Matco Services, we specialize in failure analysis and corrosion investigations in boilers and turbines. We will determine if a failure is caused by inappropriate material selection, design, fabrication or operating conditions. Major corporations that rely on Matco expertise include US Airways, General Electric, Simens, Westinghouse, Southern California Edison, Allegheny Energy, ABB Power, NY Power and many more.
The principal mechanisms by which boiler tubes fail during service are discussed as well as several important factors often associated with component failures including deficiency in design, fabrication, operating conditions, unsuitable materials selection, and expended useful life. Among the case histories discussed are: fatigue, erosion, short-term overheating, and hydrogen damage.
Common questions we address:
a. Which component failed first?
b. What was the mode of failure? How did it fail?
c. What were the trajectories of failed parts and the consequential damage?
d. What is the root cause of the failure?
e. What are the possible corrective actions?
f. Inspection procedures and inspection frequency?
An on-site inspection and investigation that enables engineers to review operating conditions and maintenance records may be essential to determine the most likely sequence of events in a failure.
.
Some of the components that we look at in a typical day include mechanical equipment; turbine and compressor blades; superheater & boiler tubes; treatment processes; pipelines; pressure vessels; forgings; castings; and welds/brazes. Based on the test results and the data obtained, the life expectancy of a component can often times be determined.
Determination of the root cause of failure of systems or components can be very complex, and may require multidisciplinary testing and analysis. The first requirement for success is having a full-equipped modern laboratory. Matco’s labs include light and electron microscopy, mechanical and electrochemical testing, chemical characterization, and fracture mechanics/FEA analysis capabilities.
The other half of the battle is having the right staff. Matco‘s staff includes experienced PhD-level Metallurgists, and Materials and Mechanical Engineering Scientists; Professional Engineers; Chemists; Paint and Coating Specialists; and NACE (National Association of Corrosion Engineers) Certified Corrosion Engineers, Materials Selection/Design, Coatings and Cathodic Protection Specialists. By combining the right equipment with the right staff, rapid and accurate determinations of the causes of failure can be made.
An illustrated formal report documents the results of the investigation. If necessary, Matco personnel can usually be on-site almost immediately when requested during emergency situations.
Please review the just released technical publications entitled "Failure Analysis and Investigative Methods for Boiler Tube Failures" and "A Re-Examination of Failure Analysis" for more information on boiler tube failures.
