Main pipe (MP)
The main pipe joins the compressor sta-
tion to the distribution network. It should
be dimensioned with adequate capacity
for future expansion.
The pressure loss in the main pipe
should not exceed
∆pMP ≤ 0.03 bar.
Distribution pipes (DP)
The distribution pipes distribute the com-
pressed air within a point-of-use section.
They can be arranged in the form of
feeder branches, a ring line or a ring line
with integrated feeder branches.
In production halls where the com-
pressed air does not have to meet any
special requirements, it is usual to install
a ring line system. The installation of
small ring lines to supply specific ma-
chines or plant groups is generally an
advantage. Where this is not possible,
i.e., where a large ring line has to be in-
stalled, it is advisable to combine this line
with feeder branches. The provision of
shutoff valves at strategic points makes
it possible to close down individual pipe-
work sections in order to carry out main-
tenance work or fit an extension.
Individual feeder branches may be in-
stalled for conveying compressed air of a
specified standard to machine groups or
other production equipment. This applies
particularly to production processes and
plant (assembly lines) where the produc-
tion layout is frequently changed resulting
in changes in the infrastructure.
The pressure loss in the distribution
pipes should not exceed
∆ ≤ 0.03 bar.
Nominal diameter (DN) of main pipe (MP)

up to 100 m and an operating pressure
