AIR LINE PIPING
(STATIONARY COMPRESSOR OUTFITS)
The use of plastic pipe, soldered joint,
or failure to insure system capability
of flex joints and
result in mechanical failure, property
damage, and serious injury.
Plastic or PVC pipe is not designed for
use with compressed air. Regardless
of its indicated pressure rating, plastic
pipe can burst from air pressure. Use
only metal pipe for air distribution lines.
A typical compressed air distribution system as shown
in Figure 2, should be of sufficient pipe size to keep
the pressure drop between the supply and point of use
to a minimum. All pipes and fittings used must be cer-
tified safe for the pressures involved. Pipe thread
sealant must be used on all threads, and all joints are
to be made up tight, since small leaks in the piping
system are the largest single cause of high operating
costs.
All piping should be sloped to an accessible drain
point and all outlets should be taken from the top of
the main distribution air line so that moisture cannot
enter the outlet.

Typical Compressed Air Distribution System
The main distribution air line should not be smaller
than the compressor air discharge valve outlet. A
smaller line will restrict the flow of air. It is recom-
mended that a flexible coupling be installed between
the air discharge valve outlet and main air distribution
line to allow for vibration.
To remove entrained dirt, oil and water, install a
separator in the main distribution line, a sufficient
distance from the compressor. This will allow the
air to cool to room temperature before passing
through the separator.
Additional separators or filter may be used depending
on the application.
For underground installation, bury air
lines below the frost line and avoid
pockets where condensation can gather
and freeze. Apply pressure before under-
ground lines are covered to
sure all pipe joints are free from leaks.
