Root Cause Analysis

FAC Failed Tube Metallurgical Analysis

Knowing the fundamental causes leading to failure is essential to make the right steps to mitigate the risk of the failure repeating.  Tetra Engineering calls on an interdisciplinary team to assess the failure (or degradation) and determine the root cause.

The assessment may include:

  • Operational Data Review
  • Metallurgical Examination in a laboratory
  • Mechanical Testing
  • Chemical and Fuel Analysis
  • Scanning Electron Microscopy
  • Finite Element
  • Boiler Process Modelling

Related and follow-up services for remediation may include fitness-for-service (FFS) or remaining life assessment, as needed.  

The underlying objective is to “use” the failure as an opportunity to improve operational practices or identify potential design problems and thereby ensure long-term reliability of the steam cycle.
