Ammonia Pipe Marking

Ammonia Pipe Marking

Stay IIAR compliant.
Mark your ammonia pipes.

If your facility has pipes containing ammonia, you must follow International Institute of Ammonia Refrigeration (IIAR) labeling requirements. These labels feature black text on an orange background and have five key components: abbreviation, physical state, marker body, pressure level, and flow direction. Choose the labels below that match the contents of your pipes. Then select the appropriate sizes. Consult our free Ammonia Pipe Marking Guide for details about ammonia pipe marking requirements.
