Elevated Temperature Design & Analysis - OCE

Performing design and analysis of equipment operating in elevated and super-elevated temperature service. President, Bill O’Donnell, Sr. co-developed the ASME design criteria for elevated temperature equipment – the O’Donnell-Porowski solution for the response of structures subjected to cyclic thermal and pressure loads. This criteria is used world-wide in the design of elevated temperature components. 

  • Creep Fatigue Evaluations
  • Creep Rupture Damage Analyses
  • Creep Ratcheting Evaluations
  • Creep Buckling
  • Weld Evaluations
  • Materials Evaluations
  • Tensile Instability Analyses
  • Heat Transfer Analysis
  • Thermal Analysis
We have resolved numerous issues in elevated temperature applications, including:
  • Thermal transient analysis of heat exchangers and other process equipment
  • Weld stress relieving of assemblies and structures
  • Thermal analysis of heat regenerators, combustion and blast furnace components
  • Failure analysis of tube-to-tubesheet welds in a Superheater

    Examples Include:

    • Nickel Alloys
    • Austenitic Steels
    • Super Alloys
    • Refractory
    • Petrochemical
    • Manufacturing
    • Process
    • Energy
    • Aerospace
    • Pressure Vessels
    • Heat Exchangers
    • Steam Turbines
    • Reactors

    Equipment operating at elevated temperatures requires a knowledge of creep, creep ratcheting and creep fatigue.

    Basic elevated temperature failure modes include ductile rupture from short-term loads, creep rupture from long-term loads, creep fatigue failure and buckling due to short-term loads. President, Bill O’Donnell has written papers on these subjects – as well as assisted in the design, analysis & troubleshooting of equipment in elevated temperature service. In addition, he has published Vessels for Elevated Temperature Service.
