The Case of...Improper Selection of a maintenance Strategy Takes Corrosion Protection from Bad to Worse

摘要

When conducting a coating failure investigation, the investigator's first inquiries should be "What was sup posed to be done," and "Does it make sense?" The answers to these questions are typically revealed in the specification for the project. However, in this "Case from the F Files," there was very little information in the specification to guide the investigation; and there was little information available from the application, because in process inspection was not performed. These circumstances made the failure much more challenging to resolve, and the resolution was based solely on the results of the field and laboratory investigations, along with the experience of the investigator.
