Abstract

This study examines the effect of the continuous decrease of the nitrite concentration on the corrosion properties of a carbon steel pipeline in deaerated synthetic tap water. Passive film, which is composed mainly of maghemite (γ-Fe ₂O ₃), was formed in synthetic tap water containing 200ppm nitrite. A carbon steel pipeline in synthetic tap water containing 100ppm nitrite was more susceptible to localised corrosion than that containing 50ppm nitrite due to the effect of the small anode and large cathode area. Uniform corrosion dominates in synthetic tap water containing 50ppm nitrite.
