Abstract
Two cases of corrosion caused failures in prestressed concrete cylinder pipelines are presented. After determining the nature of the corrosion and its causes, cathodic protection was taken as the only tool that could be applied to try to save the pipeline. This paper describes the methods used to apply cathodic protection using sacrificial magnesium anodes to a pipeline of 800 pipe sections. Also presented are the results of the first year of application.
