By applying the principles found within the IIAR Ammonia Refrigeration Piping Handbook, industrial facilities ensure:
This chapter covers proper selection and installation of hand stop valves, flow-regulating valves, solenoid valves, pressure regulators, and check valves. The valve selection process is critical to system performance and safety.

IIAR’s annual conference features four-hour courses examining all parts of the Refrigeration Piping Handbook, including the use of computer programs and nomographs for pressure drop calculations, vertical suction riser flow theory, evaporator and condenser piping methods, plant layout, welding requirements, and insulation systems for piping and equipment.
It aligns with ASME B31.5 (Refrigeration Piping and Heat Transfer Components).
The IIAR (International Institute of Ammonia Refrigeration) Ammonia Refrigeration Piping Handbook is the definitive global standard for designing, fabricating, and installing safe industrial refrigeration systems. Closed-circuit ammonia systems operate under high pressures and use a toxic, flammable refrigerant, making precise piping design a critical safety requirement.
Ammonia does not mix with oil in the same way Freon does. The handbook explains the complex piping arrangements required to separate oil from the system and return it to the compressor, specifically focusing on hot gas discharge lines and suction lines .
