Abstract
The use of sacrificial anode cathodic protection has successfully prevented the corrosion of both new and old corroding prestressed non-cylinder concrete pipelines. Field results from 5 new and 3 old lines, which have been cathodically protected for up to 18 years, are reported. In all cases the required potential difference criteria have been achieved with current densities in the range 0.2 to 1.8 mA per square metre of steel surface area.
