The compressed air pipe sizing diagram below allows you to determine the diameter of the main line.
- Choose the flow rate of compressor in the red column.
- Choose the distance between compressor and the most distant using point in the blue column.
- Cross the lines of flow rate and blue column of distance to choose the diameter.
Pressure 7 bar – Total pressure drop 4%
* Pressure drop is higher than 4%
What happens if my pipe diameter is too small?
The most overlooked area in piping layout and design is the velocity of the compressed fluid. Under-sizing the diameter of the pipe will increase the velocity.
What is wrong with high velocity?
Fluid runs through the system faster, when it hits a valve or crossing tee, all the accumulated energy creates high turbulence and therefore significant back pressure.
This back pressure in your airline can have a very negative impact on your system’s performance and running costs.
High velocity (under sizing the pipe system) can be a significant cause of:
- Erratic pressure control
- Turbulence in the pipe system
- Pressure drop, and
- Extra power requirements at the compressor
