Stress Corrosion Cracking Mitigation

Stress Corrosion Cracking (SCC) Mitigation

O’Donnell Consulting evaluates stress corrosion cracking and performs Fitness-For-Service evaluations per API-579 and ASME Section II – evaluating NDE test results, design weld repairs, and design safety constraints. We have proprietary SCC mitigation technology which has been successfully used in numerous applications.

Failures of structures often involve environmentally assisted cracking. Stress corrosion cracking (SCC) is one of the most common environmentally assisted failure modes encountered. It typically occurs due to improper materials selection or heat treatment, design issues, and unforeseen environmental conditions, i.e., inadequate maintenance, thermal transient conditions, or lack of consideration of residual stresses. We can assist you in the evaluation and mitigation of SCC – enabling you to lower costs, and improve safety.

  • Hydrogen Embrittlement Analyses
  • Weldment Residual Stress Analyses
  • Linear Elastic Fracture Mechanics
  • SCC Mitigation Applied to Weldments in Heat Exchangers, Pressure Vessels, Chemical Reactors, Nuclear Components
  • Thermal and Mechanical Stress Relieving
  • Crack Growth Analyses
  • Thermal Crack Growth Mitigation Techniques
  • Elastic-Plastic (J Integral) Fracture Mechanics

A few examples include:

  • Petrochemical
  • Oil/Gas
  • Process
  • Energy

In considering the stress corrosion cracking problem in the heat affected zone of field welds in BWR primary pumping, the O’Donnell team developed a reliable mechanical stress improvement process which applies compressive stresses and is easy to control and verify.

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!
