...Abstract NACE Standard Practice SP0204, Stress Corrosion Cracking Direct Assessment Methodology (SCCDA), is used by pipeline operators to infer the presence or absence of stress corrosion cracking (SCC) on a pipeline. Results from direct examinations of the pipeline are easy to interpret when SCC...

...Abstract Stress Corrosion Cracking of pipelines is controlled by several environmental, material, and loading factors. Therefore, SCCDA requires the operators to collect and analyze a lot of historic and current data to prioritize the protection of highly susceptible pipeline segments. For pre...

... SCCDA Crude Oil Pipeline Integrity Management In the present work, a 48 inch (~121.9 cm) diameter crude oil pipeline with a 0.375 inch (~ 9.53mm) nominal wall thickness that was coated with coal tar enamel was examined. This pipeline was installed in Kuwait in 1968 and runs from a gravity-feed...
