Corrosion: Environments and Industries
External corrosion direct assessment (ECDA) is a structured process intended for use by pipeline operators to assess and manage the impact of external corrosion on the integrity of underground pipelines. This article focuses on four steps of ECDA, namely, preassessment, indirect examinations, direct examination, and post assessment. The ECDA tool selection matrix used to determine the tool choices is also presented.
