Study the effect of soil corrosion of metal pipes (cast iron and wrought iron)

Abstract

The aim of this study is to show the extent of soil effect (soil Technical Institute / Cote) on two types of metals (cast iron and wrought iron) when immersing the two species in the soil and certain period of time, after a month of immersing the pieces in the soil were dug out the first two pieces to calculate the amount of corrosion output was the first piece weighed before immersion (892.21 g) and after immersion (886.44 g) and the second piece before immersion (543.97 g) and after immersion was weighing (497.723 g) and after two months of immersion were extracted the other pair of the pieces was the first weight (885.15 g ) the second and weight (487.97 g), and after the third month was extracted last two pieces was weigh (866.16 grams) (482.52 g) consecutive laps that the percentage of soil effect on the wrought iron than in cast iron and is due to several reasons, including the proportion of carbon, as well as elements of foundries used to have a clear effect of leading to a change in the metal corrosion response.
