3. Definitions and Purpose
Expansion joints are flexible connectors designed to provide stress relief in ducting systems by absorbing movements caused by thermal changes.
Moreover, fabric expansion joints have an extended role in terms of:
Vibration and noise isolation
Shock absorption
Compensate misalignment of ductings

4. Various types of Expansion Joints
Metallic Expansion Joints or Bellows
Non-metallic Expansion Joints
Rubber or Moulded Expansion Joints
Fabric Expansion Joints or Compensators

10. Movements Axial movement Lateral movement Torsion Angular movement
Compression
Extension
Lateral movement
Torsion
Angular movement
Vibrations
You should prefer duct systems with circular shapes rather than rectangular as the combination of axial, lateral and angular movements is more easily absorbed and it affects the joint uniformally

11. Inner sleeve design Welded to the expansion joint frame (straight)
Welded to the duct plate (semi-airfoil)
Bolted to the duct flange (semi-airfoil)
Designed as part of the expansion joint frame (telescopic)

12. Design of inner sleeve Enable free movement of joint and flanges
Protects bolster and or joint from gas and dust flow
Enable laminar flow of gas within the ducting
Should be designed according to corrosion regarding choice of material and thickness
Should ease installation or replacement of bolster/compensator
Should eventually enable cleaning of ducting
Must take into account dilatations (approx. 3 mm per meter at 300°C)

13. Bolster or stuffing mat
Function:
Thermal insulation
Acoustic insulation
Protection of expansion joint
Reduce the pulsation effect
Construction:
Retaining bag: wire mesh and/or heat resistant glassfabric or silicate fabric
Insulation: mineral or ceramic wool
Advices:
Do not use bulk insulating materials
More difficult to install in correct position
Exposure to fibres during handling and installation
Does not resist to abrasion
Quicker deterioration of expansion joint

14. Bolster or stuffing mat
It also prevents particules or dust accumulation between the inner sleeve and the expansion joint which can lead to the explosion of the expansion joint

15. Tabbed bolster Enables the bolster to stay into position
May also be pinned to the frame

16. CLAMP BARS AND FASTENERS
Clamping methods
WORM DRIVE CLAMP
CLAMP BARS AND EXTERNAL CLAMPS
CLAMP BARS AND FASTENERS
(Bolts, Nuts, Washers)
CLAMP BANDS

17. Various clamping methods
Method of clamping
Ease of installation or replacement
Cost
Suitability
Warm drive clamp
Very simple
Low
Used for small size expansion joints
Clamps bands with screw or bolt fixing
Circular shape & low pressure only
Clamps must be split into several segments
Clamp bars with bolts and nuts
Simple
Medium
Pre-formed corners with slotted holes
Do not use clamp bars too long when temperature is very high
Clamp bars fitted to stud bolts welded to joint frames
Easy but care should be taken in order not to damage studs
Medium to high
Easier when the joint is not too thick
Slotted holes in clamp bars make installation easier
Clamp bars with « U » or « E » clamps
High
Longer E clamps may be used to keep heat away from the bolt

18. Clamping methods

19. Clamping methods Clamping using « G » clamps
Used for belt type expansion joints
No need for drilling

20. The benefits of fabric expansion joints
Large movements possible in short face-to-face distance, especially with pre-set position installation
Capacity to absorb simultaneous movements in several planes
Acoustic and vibration isolation
Great possibilities regarding the design
No thermal conductivity
High resistance to corrosion
Lower replacement cost
Light weight
Easier installation and maintenance

21. Prior to installation
Please proceed to the following checkings before installing expansion joints:
Generally, do not (re-)install material which is not in good condition
Duct flanges are in good conditions and tight welded, no sharp edges in the area of expansion joint
Duct flanges and holes are correctly lined up, within tolerances
The distance between flanges in cold position is equal or inferior to installation height of expansion joint
Clamp bar side in contact with expansion joint is rounded
Inner sleeve is in good condition and correctly positionned
Bolt heads cannot get into contact with outer cover of expansion joint while expending. If it is the case, decide for design with countersunk bolt heads

22. Precautions during installation…
Large/heavy expansion joints must be supported with lifting devices during installation
Lifting devices should not be attached directly to the fabric but on the lifting lugs of a frame designed to support the joint
Protective materials or shipping bars should not be removed before installation is completed, especially when work is carried out in the area
Install expansion joint with elastomer coated surface on the outside
On horizontal ducting put the junction on the top to avoid condensation on the junction

23. Precautions during installation
The head of bolts should be placed on the backing flange side
Protect the expansion joint from surrounding activities
Do not put materials, such as scaffolding, on the expansion joint
All clamp bars should be installed and bolts and nuts hand-tightened before tightening further to the requested torque
Ask manufacturer’s recommandations regarding tightening torque
The expansion joints should not be insulated

24. Recommendations after installation
After commissioning the components of the expansion joint will settle in their operating position. By consequent, fasteners of the clamping devices should be re-tightened at the recommended torque
Expansion joints should be visualy inspected on a regular basis
During visual inspection, maintenance staff should look for signs of damage which usually occur in the form of changes of colour or peeling of the outer layer
If these sign appear you should contact the expansion joint manufactuer immediately
