General instructions
STENFLEX
®
rubber-type expansion joints can only function accurately if the installation is
performed to a skilled and professional standard. The life service duration not only depends
on the operating conditions but particularly on correct installation as required. Expansion
joints are not just simply plain piping elements. They are moving components which have to
be subjected regularly to inspection.
Expansion joints are special components of a piping system. STENFLEX

rejects all and any
warranties for imitated products or for modifications on the original products.
In order to avoid installation errors, it is very important that the following instructions
are observed with due consideration of the technical dimensional data sheets in our
catalogue.
ATTENTION: Failure to observe these instructions can lead to a destruction of the
expansion joint, injury to persons as well as causing a hazard for the environment.
In case of doubt, contact our Technical Consultation Service by calling:

Installation
Q
Store the expansion joint in a clean and dry condition. For outdoor storage, ensure
suitable protection against intensive sunshine and weather influence.
Q
Before installation, inspect the packing and the expansion joint for any damage. In the
event of damage, irrespective of its nature, the product shall not be installed.
Q
Ensure that the expansion joint is free internally and externally from foreign matter such
as dirt, insulating material and similar. Inspect the expansion joint before and after instal-
lation in this respect.
Q
Remove the transport securing elements and protection cover only immediately before
installation work.
Q
The expansion joints shall be mounted by authorised and qualified personnel only. Ap-
plicable rules and regulations for accident prevention shall be observed as required.
Q
Do not throw or hit against the expansion joint; protect it against falling items.
Do not attach chains, ropes or cables directly on the bellows.
Q
Special seals are not required as the expansion joints are self-sealing. The sealing sur-
faces of the mating flanges must be flat and clean. Additional seals are not necessary; a
seal only has to be applied when installing guide sleeves.
Q
Install rubber expansion joints with a vacuum back-up ring for sub-atmospheric pres-
sure operation.
Q
The length of the installation gap should be equal to the constructional length of the
expansion joint.
Q
The expansion joint should be preferentially loaded with compression.
