Effect of Field Bending and Girth Weld on the Initiation and Early Growth of Near-Neutral pH Circumferential Stress Corrosion Cracking (NNpHCSCC) in Thin-walled Pipeline
DownloadFall 2023
Pipeline failure because of near-neutral pH stress corrosion cracking (NNpHSCC) has been a concern in Canada for over 30 years. Previous studies focused on axial NNpHSCC, which has happened more frequently than circumferential NNPHSCC (C-NNPHSCC). This study focuses on the significance of...

Understanding the Effects of Hydrogen, Hydrostatic testing and Mill- scale on SCC of Pipelines in Near-Neutral pH Environment
DownloadFall 2016
Near-neutral pH stress corrosion cracks (NNpH SCC) are developed under coating disbondments on the external surface of pipelines where the surface of pipeline is exposed to the soil solution. NNpH SCC initiation and early stage of growth is mainly governed by the dissolution process of steel....
