What Causes Stress Corrosion Cracking? SCC is the result of a combination of three factors – a susceptible material, exposure to a corrosive environment, and tensile stresses above a threshold. If any one of these factors are eliminated, SCC initiation becomes impossible. What causes stress cracking? Tensile Stress In the case of stress corrosion cracking,
What Is Stress Corrosion Cracking In Pipelines? What is stress corrosion cracking and why does it occur? SCC in pipelines is a type of environmentally assisted cracking. SCC results from the formation of cracks due to various factors in combination with the environment surrounding the pipeline that together reduces the pressure-carrying capability of the pipe.
How Do You Prevent Stress Corrosion From Cracking? Avoid the chemical species that causes SCC. Control of hardness and stress level (residual or load). Introduce compressive stress by shot-peening for example. Use of materials known not to crack in the specified environment. What causes stress corrosion cracking? Stress corrosion cracking (SCC) is the cracking induced
