Root cause of degradation of ICCP system against corrosion for cooling water pipelines
Abstract
The impressed current cathodic protection (ICCP) combined with coating has been designed and installed to protect underground cooling water pipelines against corrosion. In order to prevent sagging, the pipelines are supported by zinc galvanised steel racking system.
This paper presents the results of the survey finding the root causes of damage and the impact of the racking system on the performance of the cathodic protection system. From these results, recommendations have been made regarding measures to assure the safe and efficient operation of the cooling water pipelines.
