Stress Corrosion Cracking (SCC) Mitigation

Stress Corrosion Cracking (SCC) 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. It is one of the most common environmentally assisted failure modes encountered.

We evaluate stress corrosion cracking (SCC) issues and develop solutions to mitigate its effects. In addition, we perform Fitness-For-Service evaluations per API-579 and ASME Section II – as well as evaluating NDE test results and designing weld repairs. Our experience includes carbon & stainless steels and other materials – on pressure vessels, heat exchangers, boilers, piping, and other process equipment.
