Thermal, mechanical, corrosion, materials/ weld, vibration, and fatigue occur on power and process equipment including pressure vessels, heat exchangers, piping and compressors. We provide engineering troubleshooting and repair solutions, keeping our clients compliant to AWS, API, ASME and other Codes – enabling them to save time, reputation, and reducing life cycle costs.
Mechanical Engineering
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.

Recent Projects
Materials & Weld Engineering
We have the answers you need, based on over 30 years experience of our Engineering Team – ensuring continued reliable service through materials & weld testing and analysis. Mechanical testing provides ductility, strength, toughness, corrosion resistance, and fatigue properties of the as-fabricated materials – providing critical materials data in the prediction of when and how materials and assemblies will fail under various loading conditions.
Our weld engineering services include joint analysis and procedure development and qualification, as well as investigating non-conformance and Code compliance – providing assistance assistance to keep you in accordance with AWS, ASME and other relevant Codes.
Examples Include:
- Heat Exchangers
- Pressure Vessels
- Condensors
- Compressors
- Petrochemical
- Mining
- Transportation
- Aerospace
- Energy
- Steam Generators
- Superheaters
- Evaporators
- Piping
Metallurgical Evaluations
Our troubleshooting services include a full spectrum of metallurgical testing including corrosion investigations, surface condition studies, mechanical and fracture mechanics testing. Read more about Metallurgy or Corrosion.
- Chemical and Mechanical Analyses
- Metallographic Examination
- Fractography (SEM and TEM)
- Accelerated Testing of Failure Modes
- Corrosion Testing
Fatigue/ Fracture 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. Read Introduction to Fatigue.
Fracture mechanics studies the propagation of cracks in materials and the material’s resistance to fracture. Analysis is done to determine residual strength in structures, develop recommended inspection cycles, and to determine repair urgency when new cracks are discovered in an existing system.
We perform fatigue and fracture analysis – and provide practical repair solutions to keep you fully operational.
Forensic Analysis
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.
