Experiments were conducted to investigate the correlation of soil properties towards metal loss of API 5L X42 carbon steel coupons, with emphasis on soil pH and resistivity. A total of four pieces of X42 coupons was placed in four different soil samples gotten from four different villages within the Nagapattinam Delta region for 2400 hours, to study the influence of soil properties towards metal loss via weight loss method. The soil coupons were buried in the soil samples placed in a plastic container, allowed to corrode naturally and then retrieved every 240 hours. The influence of soil pH value and resistivity were evaluated using the weight loss method to evaluate the corrosion rate on coupons in the different soil samples. Results showed that both parameters had an influence on buried steel, but soil resistivity had a dominating influence compared to soil pH
