What is one issue caused by electrochemical corrosion?

Electrochemical corrosion can significantly affect the integrity and functionality of pipes used in water systems. When corrosion occurs, it leads to the deterioration of the metal material that composes the pipe. This deterioration can result in the loss of material from the pipe wall, which reduces the overall carrying capacity as the cross-sectional area through which water can flow becomes smaller.

Additionally, as the internal surface of the pipe becomes rougher due to pitting and scale formation from corrosion processes, or if the pipe wall becomes thinner, there may be restrictions that further lessen the flow rate and efficiency of water transportation. Therefore, the lowered carrying capacity of the pipe is a clear and direct outcome of electrochemical corrosion, impacting the water supply system's effectiveness and reliability.

In contrast, enhanced water clarity and improved pipe durability do not result from electrochemical corrosion; rather, they are characteristics that one would hope to achieve in a well-maintained system. An increased C-factor generally reflects a smoother pipe surface, which is not a consequence of corrosion but rather a sign of new or well-maintained piping.
