Soil corrosion is a complex phenomenon which primarily depends on the nature of soil properties and other adjacent environmental factors. A handful of research papers has already been published highlighting the effect of soil properties on metal corrosion. This unique experimental setup includes two samples of buried steel pipes, one provided with an impressed current cathodic protection (ICCP) system and the other left unprotected. The two samples are placed in an artificial environment, in which the author is able to manipulate the soil properties. Copper sulphate reference electrodes (CSE) are placed in the vicinity of the pipes to obtain pipe to soil potentials. A rectifier is also included in the experiment to provide ICCP to one of the sample pipe. Various electronic sensors are placed near the pipe samples to acquire various relevant data’s. Wenner four-pin method is used to check the soil resistivity. The environmental effects on the test pipes is acquired, analysed and stored. An automated data acquisition system (DAS) is used to collect the data from various electronic devices, used in the experiment. This paper presents the details of the experimental setup used in studying the effect of chemical properties of soil on metal corrosion and analysis of the same.

 

Keywords: - Impressed Current Cathodic Protection, Copper sulphate reference electrodes (CSE), Transformer Rectifier, pH, moisture content, Wenner four-pin method, Data Acquisition System, Soil Resistivity.
