Pipes accumulate rouge from rusted equipment upstream, chlorides in the fluid passing through pipes, or exposure to high temperature steam. Rouge and micropits on stainless steel pipes resulting from rusted equipment upstream is focused on. The purpose of this project was to determine the most effective procedure to remove rouge and micropits via remediation (rouge removal) followed by oxidation (restoration of the passive layer). Coupons were rouged with HCl, remediated with citric or phosphoric acid, and passivated with hydrogen peroxide, potassium permanganate, and air. Results of interest include weight loss, a color analysis using RGB and HSV values, and changes in surface roughness.
