摘要

Deterioration could lead to destruction of materials with chemical or electrochemical reaction as corrosion. Corrosion is one of the most complicated and costly problems facing in municipal drinking water utilities. A large number of parameters affected pipe corrosion, including water quality and composition, flow conditions, biological iron activity, and corrosion inhibitors. Corrosion scales play an important role in modifying water quality in drinking water distribution systems. The corrosion scales from old water pipe lines were analyzed for their structure and composition. This paper mainly studied the deposits found in water distribution system of Municipal and protection of corrosion methods as well as to preventive measurements of the iron pipe corrosion. The corrosion scales had a shell-like, enveloping layer, covering porous deposits of iron oxide phases. Catastrophic failures are obtained in water distribution systems, so major layer will be occurred. The ground water samples were drawn from the area and subjected to physical and chemical analysis and the analysis results were used to evaluate in laboratory works.
