Design data for air pipes

Chose the diameter for the installation

Dimensioning

The right dimensioning of an air pipe is very important: A pressure decrease from 6 bar to 5 bar reduces the power of the machines and tools by up to 25%. If the final compression pressure is increased by 1 bar to compensate for decrease in pressure, costs for operating power increase by 10%.

Pressure decrease 0,1 bar on operating pressure 7 bar. The diagram below allows to determinate the diameter of the main line. By ring line halve the flow rate and the distance.
