The IIAR Ammonia Refrigeration Piping Handbook serves as the industry standard, bridging theoretical design with practical, field-proven applications for anhydrous ammonia systems. It provides comprehensive data on pipe sizing, safety guidelines regarding prohibited materials, and updated insulation standards for engineers and contractors. For more details, visit OSHA .

The handbook covers several critical areas of system architecture:

One of the most heavily utilized portions of the handbook is its appendix of sizing charts. It provides pre-calculated tables matching pipe diameters to tons of refrigeration (TR) capacities based on: Evaporating temperatures. Allowable pressure drop per 100 feet of pipe. Equivalent lengths of valves and fittings. 4. Component Piping Layouts

If liquid ammonia is trapped between two closed valves (e.g., during maintenance) and the ambient temperature rises, the liquid will expand. Because liquid ammonia is virtually incompressible, the resulting hydrostatic pressure will easily burst the pipe. The handbook outlines where to install hydrostatic relief valves to safely vent this pressure back into a lower-pressure zone of the system.

The IIAR Piping Handbook is recognized by major regulatory bodies—including the and the Occupational Safety and Health Administration (OSHA) in the United States—as a core component of RAGAGEP.

Focuses on preventing and mitigating accidental atmospheric releases. 4. Insulation, Corrosion, and Vapor Barriers

Best practices for pipe slopes, minimizing fittings, and incorporating expansion loops to handle temperature fluctuations.

Are you trying to troubleshoot an issue like or vibration in an existing facility?

Ammonia refrigeration systems experience extreme thermal swings—from hot compressor discharge gas (up to 240°F / 115°C) to ultra-low freezing temperatures (-40°F/C or lower). These temperature changes cause significant physical expansion and contraction. Thermal Movement Management
