Evaluating the corrosion problems induced by the of chlorine in pipe water facilities in Alkufra - Libya

Abstract

Corrosion processes consist of a series of electrochemical reaction occurring at the metal surface in contact with water and its constituents. Analyzes were conducted on water samples in various wells in the studied area. Electrical conductivity EC, pH, total soluble salts TDS, a negative charge ion (anion) sulphate, chloride. Through the results obtained from water analysis operations to study the rates of corrosion inside the pipes, it causes corrosion processes, temperature values ranged from 35 C0 to 37 C0 Electrical conductivity EC ranges between (206-1301) microseism/cm the pH values ranged between (7.25-7.39). TDS between (195- 736) ppm). The values the Larson Index ranged between (0.408 to 1.88). Through these values ​​obtained from analyses, the electrical conductivity values ​​were found to increase with the presence of chloride ions in the water, as well as the values ​​of the corrosion coefficients resulting from the chloride ions, showing the presence of corrosion processes inside the pipes.
