In ammonia solutions with a concentration of less than 35%, when the temperature is reduced from 145 degrees to 80 degrees, what type of heat exchange tube material should be used? Please provide some information on this.

Graphite heat exchangers are recommended. Graphite heat exchangers can be used for a long time under the boiling conditions of ammonia at any concentration without experiencing corrosion.

Ammonia water is somewhat corrosive; it is recommended to consult the corrosion data sheet! I don’t have the exact data available at the moment to tell you!

Senior, how did you choose the material later on?
