Corrosion Resistance of Pipe Materials Used in Water Distribution System

EasyChair Preprint no. 5365

Abstract

This study investigates corrosion rate behaviors of stainless steel and galvanized iron in different acid, alkali and salt concentrations. All samples were prepared based on the testing specification requirement and the mass of specimen were obtained using electronic weighing balance of sensitivity 0.001g. To obtain corrosion rate, weight loss test was conducted and the samples were immersed in three different aqueous solutions which were hydrochloric acid sodium hydroxide and sodium chloride. Diameter of the material and height were obtained using divider and meter rule to calculate the area of the specimen. Result shows that in acidic solution, the percentage mass loss in ten days were 15.3(%) and 9.17(%) for galvanized iron and stainless steel respectively. For alkaline solution, the average mass loss for ten days were 7.41(%) and 3.79(%) for galvanized iron and stainless steel respectively. For salty solution, the average mass loss for ten days were 12(%) and 4.85(%) for galvanized iron and stainless steel respectively. The rate of corrosion determined from this experiment showed that stainless steel is not totally unaffected by corrosion.

Keyphrases: aqueous solution, corrosion resistance, galvanized iron, stainless steel
