9.2.1.2. The distribution line- ring line


<BR>The distribution lines are laid through the entire operation and bring compressed air to the devices. They should always take the form of a ring line wherever possible. This increases the economy and security of operation of the line as a whole.

Pressure loss Dp in the distribution lines should be no higher than 0.03.

<BR>A ring line forms a closed distribution ring. It is possible to isolate individual sections of the network without interrupting the supply of compressed air to other areas. This provides assurance that compressed air will be available for most devices, even when servicing, repairs and extension work is being carried out.

If the compressed air is supplied through a distribution ring, the compressed air has a shorter route to travel than with stub lines. This means that lower pressure loss Dp is needed. When dimensioning the ring line one can calculate with half the flow pipe length and half the volume flow.
