Corrosion Science Section

Water wetting is a crucial issue in carbon dioxide (CO2) corrosion of multiphase flow pipelines made from mild steel. This study demonstrates the use of a novel benchtop apparatus, a horizontal rotating cylinder, to study the effect of water wetting on CO2 corrosion of mild steel in two-phase flow. The setup is similar to a standard rotating cylinder except for its horizontal orientation and th...

The effects of surface pretreatment on the rate of scribe-creep caused by underpaint corrosion on coated AA2024-T3 (UNS A92024) were investigated. Scribe-creep experiments were conducted on epoxy polyamide-coated (average coating thickness: ~10 μm) AA2024-T3 in 80% relative humidity at 25°C, 40°C, and 50°C. Scribe-creep was observed to be enhanced by exposure test temperature regardless of surf...

Corrosion Science Section

An experimental prototype, comprising a buried pipeline, was built with the purpose of calibrating a transmission line model and an artificial neural network (ANN) algorithm for locating and assessing the severity of external corrosion damage of defects in the pipeline’s coating when the pipe was subjected to different levels of cathodic protection (CP) and to different environmental scenarios....
