Examples of Design for

2 Examples of Design for Cathodic Protection Systems † Soil resistivity in the service area. † Structure to soil potential shift required to produce polarization needed to meet ca- thodic protection criteria. This is the immediate change in potential of an isolated structure measured to a point at “remote earth” when cathodic protection is applied.ICCP or sacrificial anodes for buried tanks? - Cathwell,Sacrificial anodes. The most commonly used anode material for external protection of buried tanks is magnesium, and the voltage difference between steel and a magnesium anode is 1.2 to 1.8 V (depending of type of magnesium alloy used).. Magnesium anodes can protect underground tanks in most soil conditions, however, most suitable for use in ground with moderate resistivities.TS 0440 Cathodic Protection Part 1 - Pipelines,AS 2239 Galvanic (sacrificial) anodes for cathodic protection AS 2832.1 Cathodic protection of metals, Part 1: Pipes and Cables AS 3000 Wiring Rules AS 4827.1 Coating defect survey for buried pipelines Part 1: Direct current voltage gradient (DCVG) AS 4832 Cathodic Protection - Installation of galvanic sacrificial anodes in soil
