Pipelines, which are mostly buried for the conveyance & distribution of gas, water & other hydrocarbons are particularly prone to corrosion – which can result in serious consequences. Typical examples are as follows: • Conveyed-product leaks – at times accompanied by explosions & fires when gas or other hydrocarbons are involved; • Contamination of water being conveyed in pipelines; • Pollution of the soil, streams, waterways & shallow or deepwater estuaries; • Interruption to services resulting in high equipment replacement & installation costs; • Reducing the pressure rating of the pipeline as a result of deterioration caused by corrosion. These costly drawbacks and damages could be avoided if pipelines were provided with effective cathodic protection. However cathodic protection could only be effective if the pipelines were: • Provided with a high quality insulating
