Which material should NEVER be used in ammonia refrigeration systems due to corrosion risk?
Understand the Problem
The question is asking for the material that is not suitable for use in ammonia refrigeration systems because it risks corrosion. It is testing knowledge about material compatibility in specific applications.
Answer
Copper and copper alloys
The material that should NEVER be used in ammonia refrigeration systems due to corrosion risk is copper and copper alloys.
Answer for screen readers
The material that should NEVER be used in ammonia refrigeration systems due to corrosion risk is copper and copper alloys.
More Information
Ammonia can cause stress corrosion cracking in copper and its alloys, which makes them unsuitable for use in refrigeration systems where ammonia is present.
Tips
A common mistake is assuming that all metals are compatible with ammonia; however, copper is particularly susceptible to corrosion.
