Which of the following conditions prevents the use of copper and copper alloy piping in power plants?

Copper and copper alloy piping is often used in various applications, but certain conditions can limit its use, particularly in power plants. One significant factor is high temperature. At elevated temperatures, copper can become susceptible to various forms of deterioration, including oxidation and softening, which can compromise the integrity of the piping system. This makes copper less suitable for high-temperature applications often encountered in power plants, particularly those involving steam and heat transfer.

In environments where temperatures can exceed the operational limits of copper, it becomes critical to select materials that can withstand the stress and strain without failure. This is crucial for maintaining safety and efficiency in power generation processes. Thus, high temperature being a prime factor directly influences the decision to avoid using copper and copper alloys in those particular scenarios.
