COMPRESSED AIR PIPE SIZING CHART mm ID

Compressed air systems rely on correctly sized piping to maintain pressure, efficiency, and performance. The internal diameter (ID) of the pipe determines how much air can flow without excessive losses. This chart provides typical pipe sizes in millimetres for given air flow rates and line lengths, supporting accurate design of pneumatic and process systems.

Based on a straight pipe run at 7 bar and 0.3 bar pressure drop. Add bends and fittings values separately.

Proper pipe sizing is essential to minimize pressure drop and energy waste. Undersized lines restrict air flow, causing compressors to work harder, while oversized lines increase installation costs. Selecting the correct diameter ensures stable pressure delivery for actuators, valves, and pneumatic tools throughout the system.

In fluid handling and food processing environments, compressed air often powers pumps, conveyors, and control systems. Maintaining consistent air pressure ensures reliable equipment performance and hygienic operation. Using this chart during design or expansion helps engineers plan efficient, balanced air distribution networks.

Pressure losses grow with pipe length, fittings, and bends, so total system layout must be considered. By referencing equivalent pipe lengths and selecting appropriate diameters, engineers can optimize performance and reduce compressor energy consumption, which is a major operational cost in many facilities.

Accurate pipe sizing improves system reliability, extends equipment life, and reduces maintenance requirements. This table serves as a practical guide for specifying air lines in industrial and food-grade applications, ensuring efficient operation and compliance with safety and performance standards.
