Corrosion in pipe networks is primarily caused by the interaction of the pipe material with its environment, notably the presence of dissolved oxygen in the water.
The Role of Dissolved Oxygen
According to our reference material, dissolved oxygen is a key factor in pipe corrosion. Specifically:
- Oxygen's Interaction: Dissolved oxygen in water contributes to corrosion by interacting with the metal interior of the pipes.
- Copper Piping: It is predominantly oxygen that causes copper corrosion when it comes into contact with copper piping.
Mitigation Strategies
Addressing corrosion in pipe networks often involves strategies to minimize the presence or impact of dissolved oxygen. Some of these strategies include:
- Oxygen Removal: Employing methods like chlorination or ozone systems to remove dissolved oxygen from the water supply can reduce corrosion.
Other Contributing Factors
While dissolved oxygen is a primary cause, other factors can also contribute to corrosion in pipe networks:
- pH Levels: Highly acidic or alkaline water can accelerate corrosion.
- Water Velocity: High water velocity can erode protective layers on the pipe's interior.
- Presence of Salts: Certain salts in the water can increase its conductivity and promote corrosion.
- Microorganisms: Certain bacteria can contribute to corrosion through biological processes.
