Buried copper (Cu) pipes are often fitted with zinc (Zn) strips, also known as a protective coating or encapsulation layer.

Cu pipes are commonly used in various applications such as plumbing, electrical wiring, and chemical processing industries due to their high thermal conductivity, corrosion resistance, and durability. However, Cu pipes can be exposed to environmental factors such as moisture, temperature changes, and chemicals that can cause damage to their surface.
One of the primary reasons for the use of Cu pipe protection is the potential for exposure to environmental hazards. For example, water containing salt, calcium carbonate, and other minerals canCu pipes over time. Additionally,Cu pipes may be exposed to environmental pollutants such as acids, alkalis, and other substances that can accelerate the process.
Another reason for the use of Cu pipe protection is the potential for physical damage caused by exposure to temperature changes and chemicals. For example, Cu pipes can expand and contract when subjected to changes in temperature, which can cause stress on their structural integrity. Similarly,Cu pipes can react with chemicals in various environments, leading to rusting or corrosion.
To prevent these types of damages, Cu pipes are often fitted with a protective coating or encapsulation layer made of zinc (Zn). This coating provides a barrier between the Cu pipe and its environment, protecting it from harmful chemicals, moisture, and temperature changes.
The choice of Cu pipe protection material depends on several factors, including the type and location of the, the level of environmental exposure required, and the desired durability and resistance to corrosion.
Zinc (Zn) is a good choice for Cu pipe protection because it is highly resistant to corrosion, has low reactivity with moisture and certain chemicals, and can form a stable film over the Cu pipe’s surface. Zinc can be applied to Cu pipes using various methods, such as electroplating, sintering, or mechanical exfoliation.
Once the protective coating is installed, it will provide an additional layer of protection against environmental hazards and physical damage. The copper pipe remains protected even if it is subjected to harsh conditions, such as extreme temperatures or chemicals, and can continue to function without degradation.

In conclusion, Cu pipes are often fitted with zinc (Zn) strips as a protective layer to prevent damage from environmental hazards, temperature changes, and chemicals. The choice of the protective coating material depends on several factors, and choosing the right one can ensure the longevity and performance of Cu pipes.
