Root Cause Failure Analysis
Components not meeting their intended design life, or accidents and failures often result from factors including:
- Design errors
- Material imperfections
- Manufacturing issues
- Welding issues
- Improper heat treatments
- Misuse or abuse
- Improper maintenance
- Unforeseen operating conditions
- Inadequate quality assurance
- Inadequate environmental controls (Vibration, Corrosion, etc)
Interdisciplinary teams are essential for performing most failure analyses, since the root cause is rarely the result of a single variable. Understanding not only the metallurgical properties but also the environmental effects and stresses to a system or component is important in determining the cause of a material failure.
Once we identify component failure modes, we assess component remaining life, recommend inspection methods/ intervals, develop repairs to components and modify equipment designs to reduce the likelihood for future failures and ensuring structural integrity.
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.
