What type of corrosion occurs primarily due to high velocity in copper pipes?

The type of corrosion that occurs primarily due to high velocity in copper pipes is known as erosion corrosion. This process happens when the flow of water at high speeds creates turbulence that disrupts the protective oxide layer on the surface of the metal, leading to increased wear and removal of material.

In this scenario, the high velocity of water can cause localized damage to the copper pipe, allowing the corrosive nature of the water to penetrate and contribute to further corrosion rates. This is particularly evident in areas where there are bends, fittings, or other changes in direction within the piping system, which can enhance the velocity and turbulence of flow.

Understanding erosion corrosion is important for water operators as it helps identify conditions that may lead to pipe failures and informs maintenance practices to mitigate such risks, ensuring the integrity and longevity of the piping system.
