What should be used to prevent pipe corrosion when installing copper pipes?

Using electrolyte isolation is an effective method to prevent pipe corrosion when installing copper pipes, especially in situations where dissimilar metals come into contact. Electrolytic corrosion occurs when two different metals are connected in the presence of an electrolyte (such as water), leading to unwanted chemical reactions that can damage the pipe. By ensuring that copper pipes are isolated from other metals, you can significantly reduce the risk of corrosion. This isolation can be achieved through the use of insulating materials or fittings that prevent direct contact between the copper and other metals.

In contrast, plastic sleeves, anti-corrosion chemicals, and pipe insulation may provide some level of protection, but they do not address the root issue of electrolytic interaction between dissimilar metals. Plastic sleeves may simply cover the copper without preventing galvanic action. Anti-corrosion chemicals can help reduce corrosion but may not be practical for long-term use in all applications. Pipe insulation primarily addresses temperature control and moisture, rather than directly preventing corrosion. Thus, electrolyte isolation is the preferred strategy for effectively preventing pipe corrosion in copper installations.
