Copper Pipe Corrosion
Why Do Copper Pipes Corrode?
While copper is known for its durability and resistance to rust, it is not completely immune to corrosion. Several factors can contribute to the deterioration of copper pipes over time, including:
- Water Chemistry: High acidity (low pH) in water can accelerate corrosion.
- Dissolved Oxygen & Minerals: Excess oxygen and minerals in the water can lead to oxidation, forming pinhole leaks.
- Velocity of Water Flow: High-speed water can cause erosion corrosion, wearing down the inside of the pipes.
- Electrochemical Reactions: If copper pipes are in contact with other metals, a process called galvanic corrosion can occur, leading to accelerated deterioration.
- Sediment & Contaminants: Buildup of debris, chlorine, or sulfate compounds in the water can contribute to corrosion over time.
How Does AQUABION Protect Against Corrosion?
Once the AQUABION has been installed, the zinc sacrificial anode helps protect the pipeline system. Since zinc is a less noble metal than copper, the zinc anode is oxidized (corroded) first, rather than the pipe wall.
This process creates a thin, protective boundary layer inside the pipe, preventing direct contact between the water and the copper surface. This scientifically proven effect is similar to methods used in ship hull and boiler protection, ensuring long-term resistance to corrosion.
Long-Term Benefits of AQUABION
By preventing corrosion, the AQUABION system extends the lifespan of your pipework, reducing costly repairs and replacements. Unlike chemical-based treatments, AQUABION operates without electricity or regular maintenance, making it an eco-friendly and cost-effective solution.
Whether in homes, businesses, or industrial settings, AQUABION provides a long-term safeguard against pipe deterioration, ensuring a reliable water system for years to come
The effect is known and scientifically proven. In industry, the effect is used for the protection of ship hulls and boilers.
