    Pipe Contamination in NH3 Systems

    This morning one of my clients asked me to look into a problem they have found in the ammonia piping. They were noticing a small ammonia smell in a freezer.

    Upon inspection they found this flange that was leaking. When they took the flange apart to replace the gasket and inspect the flange, they found the stuff you see in the picture.

    I'm still looking into the details for location of this flange, etc. I will post more information as it becomes available.

    Has anyone seen anything like this before? This is a new situation I have not seen before.
