Abstract

Corrosion of metallic water pipelines is a function of the pipe's surrounding environment (soil and water) This means that it is important to know the physical and chemical characteristics of the pipe's surrounding environment The corrosion of externally unprotected metallic water pipelines, particularly ductile iron pipes, in localities with aggressive soil conditions is becoming a significant problem repair and replacement costs are high, and failures cause supply interruptions to customers and inconvenience to the public Anti-corrosive protection for metallic water pipelines, their fittings and accessories is very important, because they may be attacked by corrosion with time The tendency of a metallic substrate to corrode is a function of the surface characteristics of the metal and of the metal/protective film Interface, the physical, electrical and electrochemical properties of the film, and the nature of the environment in which the pipelines system is placed
