Corrosion of carbon steel in synthetic freshwater for water distribution systems

Abstract

Corrosion is one of the most common problems in water distribution systems. The purpose of this research is to investigate the corrosion rate of carbon steel in synthetic freshwater. The influence of a variety of time exposure that represents the actual conditions in practice was performed. Research conducted by weight loss methods using immersion test. The parameters of water quality were measured by using a multimeter portable (Hach HQ40d). From the experiments obtained that the corrosion rate of carbon steel in freshwater ranged between 0.41-0.76 mpy. The results of this study are expected as a first step, as input for prevention, to prevent leakage flow and pipe due to corrosion by the life that has been designed.
