Influence of Ultrasonic Nanocrystal Surface Modification on the Corrosion and Stress Corrosion Cracking Behavior of Welded Joint in District Heating Pipe

Picture for Influence of Ultrasonic Nanocrystal Surface Modification on the Corrosion and Stress Corrosion Crack
Available for download

Stress corrosion cracking behavior measured by slow-strain rate tests with accelerated anodic & cathodic reactions. Results indicated the UNSM treatment has a significant effect on the corrosion condition. No effect appeared in the hydrogen embrittlement.

The effect of ultrasonic nanocrystal surface modification (UNSM) on the corrosion and stress corrosion cracking behavior of welded joint in district heating pipe were investigated. After UNSM treatment the microstructure of welded joint was transformed from the grain boundary ferrite widmanstatten ferrite to polygoanl ferrite and refined the grain. In the electrochemical tests the corrosion resistance of welded joint was increased after UNSM treatment due to the grain refinement and stability of oxide film. The stress corrosion cracking behavior was measured by slow-strain rate tests with accelerated anodic and cathodic reactions. The results indicated that the UNSM treatment has a significant effect on the corrosion condition whereas no effect appeared on the hydrogen embrittlement.

Key words: weld, steel, corrosion, stress corrosion cracking, polarization

How Many Excavations are Required to Confirm the Absence of SCC on a Pipeline Following SCCDA

This paper examines the relationship between stress corrosion cracking (SCC) threat modeling and the number of digs required to conclude that a pipeline is SCC free. Results show that when a reliable inspection prioritization model is used, few digs are required to infer that a pipe has a low probability of SCC.
