Effect of soil resistivity in Pekan campus to the corrosion behavior of steel pipe system

Underground pipe system will place at different place and will pass through the different soil structure. This different soil condition has different soil resistivity that will give the different result of the corrosion rate at same pipeline system. In this experiment, soil resistivities of differen...
