Providing engineering troubleshooting and repair on (pressure vessels, heat exchangers and other process equipment) with issues including thermal, mechanical, corrosion, materials/ weld, vibration, and fatigue – keeping our clients compliant to AWS, API, ASME and other Codes.
We have solved problems in applications including prototypes, production lines, and field failures – enabling our clients to save their time and reputation, as well as minimizing total cost of equipment ownership.
We were asked to investigate the failure of a splined clutch power transmission shaft. This macrophotograph at 7x shows a broken tooth with simultaneous fatigue initiation at the root radius of each side of the tooth. Reverse loading ultimately lead to fatigue fracture.
Materials & Weld Engineering
To ensure continued reliable service, we provide materials & weld testing and analysis. Mechanical testing provides ductility, strength, toughness, corrosion resistance, and fatigue properties of the as-fabricated materials. Such testing assists in the prediction of when and how materials and assemblies will fail under various loading conditions. Our weld engineering services include joint analysis, procedure development and qualification, process and filler-metal selection, as well as investigating non-conformance and Code compliance. We provide assistance to keep you in accordance with AWS, ASME and other relevant Codes.
A few examples include:
- Heat Exchangers
- Pressure Vessels
- Chemical and Mechanical Analyses
- Metallographic Examination
- Fractography (SEM and TEM)
- Accelerated Testing of Failure Modes
- Corrosion Testing
Fatigue/ Failure Analysis
Fatigue is one of the key contributing factors to the degradation of aging components. Fatigue failures occur when these structures are subjected to cyclic stresses and strains over time. This leads to the development of micro-cracks in the most highly strained locations, which subsequently propagate until the component fails. We investigate the factors that contribute to structural failure – and provide practical repair solutions to get you fully operational.
Often, various technical issues may reach litigation. We provide forensic engineering services to predict how components have failed – providing results that are easily understood by Judges and Juries. We have testified in State, Federal, and International Courts, in both defendant and plaintiff cases. Some of our projects have included:
- Materials/weld and construction issues on a Coke Oven Battery
- Investigation on a failed pressure vessel used to make crystals for cell phones
- Forensic investigation over a newly constructed collapsed Paper Rack Storage Facility
Learn from the experience of others. Especially when one such “other” is Dr. William O’Donnell, PhD, PE, Founder and President of O’Donnell Consulting Engineers, Inc., and ASME “Engineer of the Year” – his 50 years of experience in analysis of components including fatigue and fracture safety evaluations and failure analyses are now comprised in this volume.
If you are interested learning more in Engineering Design, Manufacturing and Construction, as well as Failure Analysis, then this book is a must have!
