Note
Border sealings made of NBR (nitrile rubber) are suitable
for the use in the food sector (FDA approval available).
In the area of explosive gases and dusts the earthing of all
pipeline parts must be checked after the installation.
Conductive border sealings made of EPDM do not make
conductive connections with primed pipe parts due to the
insulating paint.
– Refinish damaged flanged edges (e.g. realign).
– Remove irregularities from the flanged edge (e.g. paint
bubbles, zinc drops).
– The weld seam at the flanged edge must not be ripped.
– Do not reuse damaged border sealings.
– The pipework must be laid free of tension.
– The flanged sealing ring must not form any loops during
the tension ring installation.
– Horizontally installed lines must be supported approx.
every 4 m. If there are several short pipe parts in the
line, the distance of the support points should be re-
duced. The same applies in case of additional loads.
Outgoing lines must be secured in a way that they do
not create a torque in the main line.
CAUTION
With primed pipe parts the contact points must be freed
from the primer! A possible corrosion protection must be
conductive. (e.g. zinc spray).
CAUTION
Upon fastening the earthing bridge the tension ring screw
must be secured against unscrewing.
 Screw the earthing bridge on the projecting thread of
the tension ring screw.
 Tighten the earthing bridge with a torque of 8 to 10 Nm.
Note
– A thread projection of 8 mm suffices to secure the
earthing bridge.
– Required tools: Pliers and wrench SW 13 (better ratchet).
 After installation, remove the transport lock by means
of the pliers.
The joints are permanently pressed onto both pipe
parts by means of spring force.
 Check the spring tension by moving the joints after in-
stallation.
Should the spring force not suffice at extreme junctions, it
can be increased by the installation of one or two short
springs on the joints.
