Safety
Equipotential bonding
According to German standard VDE
0190, equipotential bonding is required
between all types of protective conductor
(PE) and existing “conductive” pipes.
However, BEKOFLOW pipes are not
electroconductive and can therefore not
be used for equipotential bonding as
stated in DIN VDE 0100.
Jointing system
Compressed air networks have to be
tight to avoid loss of compressed air and
unnecessarily high operating costs.
Leaks in the pipe network will mainly be
found at the various joints.
Pipes and fittings (couplings, etc.) should
be continuity bonded. By continuity bond-
ing one understands direct homogeneous
bonding between the pipe and the con-
nection element without the use of any
additional substances such as adhesives.
A continuity-bonded connection can only
be undone by complete destruction.
Resistance welding for PB joints
Vibrations
Vibrations are the root cause of most ir-
regularities in compressed air networks.
Therefore, it makes sense to use a pipe
system that prevents the propagation
of vibrations. Contrary to metal pipes,
BEKOFLOW
®
pipes are flexible and can
be used to provide a vibrationless pipe
system.
Pipe laying system
Pipe laying is dealt with here under the
aspect of “material selection”.
The BEKOFLOW
®
pipes recommended
by us are more than 80 % lighter than
steel pipes manufactured to DIN 2440. In
view of the flexibility of these pipes and
their low weight, the scope for pipe instal-
lation is greatly increased.
Efficient preparation as well as simp-
le and fast installation are decisive for
keeping the installation costs as low
as possible.
Because of their low weight,
BEKOFLOW
®
pipes and fittings can
be laid in or fixed along existing cable
ducts.
