Performing engineering failure analysis services – resolving materials, weld, vibration, fatigue, and other operational issues to prevent recurrence. Ensuring structural integrity, and maximizing equipment reliability & controlling costs for owners/ users.
We are a team of engineers, metallurgists & weld experts investigating the root cause of structural and weld failures due to thermal/ transients, vibrations, thermal fatigue and more.
Applications include aluminum, stainless steels, titanium, nickel based and exotic alloys used in aircraft, petrochemical plants, industrial machinery, automotive components, medical equipment, ASME boilers and pressure vessels and oil/gas pipelines. Other applications include:
- Compressors, Pipes, Valves, Pumps
- Tanks, Reactors, Dryers, Autoclaves
- Turbomachinery, Shafts, Blades, Gears, Bearings
- Heat Exchangers, Steam Generators, HRSGs
- HVAC Systems, Boilers and Industrial Furnaces
- Materials, Paints, Coatings
- Machinery, Lift Trucks, Cranes, Welded Structures
For a more comprehensive list, see Industries Served.
Root Cause Failure Analysis
Components not meeting their intended design life, or accidents and failures typically occur due to fatigue, but other factors may include:
- Misuse or abuse
- Improper Maintenance
- Unforeseen Operating Conditions
- Inadequate Quality Sssurance
- Environmental Issues (Vibration, Corrosion, etc.)
Interdisciplinary teams are essential for performing most failure analyses, since the root cause is rarely the result of a single variable. In performing metallurgical failure analysis, we investigate operational issues, environmental factors, load paths and stresses to a system or component.
Once we identify potential component failure modes, we recommend inspection methods/ intervals, and design solutions to reduce the likelihood of future failures.
In elevated temperature applications, complicated failure modes may occur, such as creep ratcheting, rupture, and creep fatigue. Our engineers have the expertise, technology, and experience to identify and quantify these failure modes – helping you understand the root cause and developing solutions to prevent costly recurrences, thus improving safety and lowering operating costs.
