| Abstract | ||
| In this research, the effect of soil resistivity on the sacrificial cathodic protection of a pipeline steel of oil was studied. Sufficient sacrificial cathodic protection could be obtained at various soil resistivty for different types of anodes. High current output (2.98, 2.38 and 8.33 Amps) of Zn, Al and Mg anodes respectively, are obtained at 25 ohms.cm soil resistivity. Simultaneous, for the same conditions, low numbers and large weights of anodes are required to satisfy protection. | ||
