ACCESSORIES<br />
Strip inserts<br />
These protect the sealing collar during increased mechanical or chemical loads in the area of the pipe end. Strip<br />
inserts are required for:<br />
– large pipe end gaps – external pressure (e.g. underwater pipes)<br />
– axial movements (expansion/contraction) – high temperatures<br />
– large misalignments and axial shifts – fuel applications<br />
– Vacuum / underpressure (e.g. suction line) – rubber swelling due to chemical contact<br />
Installation can also be carried out at a later date for all<br />
couplings. The material selection is determined by the<br />
medium and the temperature. Plastic strip inserts for<br />
normal temperatures and chemicals, steel strip inserts<br />
for higher temperatures, vacuum and external pressure.<br />
Combinations of plastic and steel are also possible. Tprofile<br />
strip inserts prevent the coupling moving due to<br />
axial changes in length and dynamic variations of load on<br />
the pipe system.<br />
OPEN-FLEX fitting pliers<br />
OPEN-FLEX couplings are opened during installation and<br />
closed around the pipe. The cut collar must be pressed<br />
with a certain force to achieve a perfect seal. At the same<br />
time, the rubber collar presses on the metal bridge of the<br />
coupling and thus makes it difficult to easily reinsert the<br />
locking bolts. This pressing force can be applied easily<br />
and saving energy with the OPEN-FLEX fitting pliers.<br />
Earth connector<br />
In contrast to STRAUB-GRIP couplings, FLEX/OPEN-FLEX couplings have no electrical conductivity and should be<br />
considered as insulating connections. If required, an electrical bridge from pipe to pipe can be established using<br />
a metallic earth connector, which is laid in the coupling. The STRAUB earth connector replaces the external cable<br />
bridge.<br />

Torque wrench<br />
It is a requirement to use a torque wrench for the successful<br />
installation of a coupling. The range of torque required<br />
can be covered with three torque wrenches.<br />
