Recent Completed Project on 'Root Cause Failure Analysis of a Push Plate Sub Sample' for an Asian Power Plant

ETD is pleased to announce the successful recent completion of a failure analysis project.

An Asian based client approached ETD to provide a quotation to perform Root Cause Failure Analysis (RCA) of a push plate sub sample.

The scope of the work carried out was:

  • Visual examination of the sample including component appearance, evidence of corrosion and/or other surface defects;
  • Assessment of condition of the surfaces;
  • Dimensional examination of the sample to examine the thickness;
  • Chemical analysis of base material to determine the chemical composition of the sample material to establish actual material constituents;
  • Metallographic examination of the sample using optical microscopy to assess the condition of surfaces, material degradation and also to identify the damage mechanism(s);
  • Further assessment using Scanning Electron Microscope (SEM) to confirm the damage mechanism;
  • Hardness testing and evaluation to determine the equivalent tensile strength values (using published hardness/UTS correlation tables) to assess the mechanical strength or softening of the sample materials or welds;
  • Basic review of design drawings, operating parameters, previous failure and maintenance history.
  • Root Cause Failure Analysis (RCA) based on the findings of above investigations.
  • Report covering results of investigations, RCA and recommendations for any further actions to be taken for safe operation of the components.
