Cyclones
When installing a cyclone in the pipe system, it is
important to obtain the right entry angle.
Do not install a bend turning in the opposite direction
of the cyclone right in front of the entry. If this is done,
the effect of the cylone is more or less neutralized.
If it is necessary to install a bend prior to the cyclone,
it shall bend in the same direction as the cyclone, or a
straight pipe of minimum 1 m (3.3 ft) must be installed
between them.
Back-pressure
If material is being blown into for example a container
with inadequate air outlet the back pressure will reduce
the conveying capacity. Open the container to allow air
to escape.

Supports
The pipe line shall either be supported or suspended
at a distance of max. 4 m (13 ft). Furthermore, it is
recommended to support the pipe as close to the
bends as possible.
Connections and centering
When connecting the pipes, bends and other material,
which are designed for high speed conveying , it is
important to center the pipes as precisely as possible
at the connecting points.
Do not rely on centering the pipe with the clamps
alone. The clamp is designed for pressing the OK-pipe
ends very hard together in order to ensure a very high
tightness. This causes the friction between the
pipes to become so high, that the clamp is unable to
center the pipes. Check gap between clamp and pipe
to ensure it is similar on both sides. Check the pipeline
visually to secure a straight line.
If the pipes are not centered, the wear on the
connection result in a fast wear out.
If a completely tight connection is required, the
connection can be winded with sealing tape before
installing the clamp.
OKD downpipe material
Do not use OKD downpipe bends and diverters in a
pneumatic conveying system. Down pipe components
are not airtight, resulting in loss of capacity and
damage to the material.
