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.
In this work the authors have looked at the corrosion problems of metallic
water pipelines and their control. The corrosive properties of water and soil
environments are reviewed. Parameters affecting corrosion are discussed. The
pollution of drinking water transported by metallic pipes caused by corrosion is
discussed. The purpose of this work is to provide guidelines for materials
selection in water and soil environments, and how the water pipelines can be
protected against metallic corrosion.
Keywords: corrosion of metallic water pipelines, drinking water pollution,
corrosive water, metallic water pipes.
