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