Performing design and analysis of pressure vessels and 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.
- Thermal transient analysis of heat exchangers and other process equipment
- Weld stress relieving of assemblies and structures
- FEA Analysis of Elevated Temperature Vessel
- Thermal analysis of heat regenerators, combustion and blast furnace components
- Failure analysis of tube-to-tubesheet welds in a Superheater
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 performed the design, analysis & troubleshooting of equipment in elevated temperature service. Two such papers he co-authored are Vessels for Elevated Temperature Service and
Creep Tensile Instability Solutions in Design Applications.
