IIAR Ammonia Refrigeration Piping Handbook
The is the definitive technical resource for the design, installation, and maintenance of closed-circuit ammonia refrigeration systems. Published by the International Institute of Ammonia Refrigeration (IIAR), it serves as a bridge between high-level engineering principles and practical, on-site application. Purpose and Scope
- Galvanized steel (zinc reacts with ammonia to form a catalyst for corrosion).
- Copper and brass (ammonia attacks copper).
- Gray cast iron (brittle under thermal shock). It recommends ASTM A53 Type E or A106 seamless carbon steel for most applications.
Industry training courses:

- Require qualified welders and documented procedures (WPS/PQR). Conduct radiographic or dye-penetrant inspection per code or company quality program.
- Avoid onsite brazed copper in ammonia service; brazed joints with copper alloys can embrittle or fail in ammonia.
Material Selection:
It specifies the use of carbon steel (typically Schedule 80 for smaller lines and Schedule 40 for larger ones) and stainless steel, while strictly forbidding copper and brass, which ammonia rapidly corrodes. Galvanized steel (zinc reacts with ammonia to form
