What type of pipe is not acceptable to use with R-717 refrigerant?

Explanation:
R-717 is ammonia, and ammonia is corrosive to nonferrous metals like copper and its alloys. Copper and bronze alloys are particularly susceptible to corrosion in ammonia systems, especially when moisture is present, which can lead to leaks and compromised joints. For this reason, piping made from copper or copper alloys is not suitable for R-717. Instead, carbon steel or stainless steel are typically used in ammonia refrigerant systems because they resist ammonia corrosion and provide the necessary strength.
