EAGLEBURGMANN
Test & Quality Inspection
Low cycle fatigue test rig.
High cycle fatigue test rig.
Raw materials, semi-finished products and complete
expansion joint constructions undergo both general
and comprehensive tests and control procedures.
These tests and control procedures include recog-
nized standard tests according to DIN norms etc.
and more advanced tests which simulate the actual
conditions, under which the expansion joint construc-
tion must operate.
Entry control
plays an important role in ensuring that the quality
of expansion joints is constantly maintained at the
highest possible level.
EagleBurgmann KE has in-house capabilities to test:
±
flexibility
±
temperature resistance
±
tensile, abrasive and tear strength
±
mechanical strength
±
chemical resistance
±
heat convection
±
recovery rate after compression
±
fibre size and number
±
weaving and the strength of same
The chemical resistance of our products are veri-
fied using our in-house test rig where the material
is exposed to concentrated aggressive media in an
accelerated environment. The tested material is then
checked carefully to determine what damage (if any)
the material has sustained.
Fabrics that are exposed to high temperatures must
maintain their mechanical properties to a certain
extent. These materials are therefore subjected to
high temperature for a specific period of time and
then tested to ensure that their mechanical proper-
ties are retained within an acceptable level.
In-house lifetime simulation
can be performed on request by EagleBurgmann KE
developed test equipment. Lifetime can be simulated
on our high cycle fatigue or low cycle fatigue move-
ment simulator. The simulator will test expansion
joint units in axial or lateral direction, and test the
material to a total of 100.000 movements.
Application technology
i.e. to know the requirements imposed on an expan-
sion joint from different processes and industries,
play a major role in order to design the right expan-
sion joint.
Based on our test and research results, we are able
to document the operational reliability and lifetime of
an expansion joint for a given application. We also
carry out customer-specific tests.
By default, all expansion joint constructions can be
测试方面:
±
flexibility rate of the expansion joint type
±
leakage rate of the expansion joint type
±
sound insulation properties of the expansion joint
±
temperature distribution (heat/energy loss)
through the expansion joint
±
FEM (Finite Element Method) of expansion joint
and steel parts with regard to life and fatigue
Each product undergo final inspection before being
shipped from the factory ensuring that the delivered
product lives up to customer expectations.
