WELCOME

The company

• Origins back in 1923: FERODO / VALEO• First expansion joint in 1955• 2005 creation of FERLAM COMPENSATEURS• 50 years experience in the design, manufacture, delivery

and installation on site of fabric expansion joints• Located in Roubaix in the North of France• Easy access to transport network: major European ports,

Motorways and Airports

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 isolationShock absorptionCompensate misalignment of ductings

Various types of Expansion Joints

• Metallic Expansion Joints or Bellows

• Non-metallic Expansion Joints Rubber or Moulded Expansion Joints Fabric Expansion Joints or Compensators

Our typical customers– Power generation

– Steel and aluminium– Waste incineration– Pollution control and flue-gas cleaning – Pulp and paper– Food processing– Heating and ventilation– Sugar refineries– Engineering Companies

Fabric expansion joints

• Air and flue gas duct systemsFiltration, de-dusting, ventilation, drying…

• BoilersCasing, heater…

• Gas turbinesGas turbine exhaust, diverter, HRSG, chimney

• Furnaces, Cyclon tower, Clinker

Multi-layer joints• 1) Supporting layer

Stainless steel wire mesh Wire reinforced fabric

• 2) Insulating layer Glassfabric or glass felt Mineral wool Silicate fabric or silicate felt Ceramic felt

• 3) Chemical barrier PTFE film Fluoroelastomer

• 4) Outer cover Silicone elastomer EPDM (Teflon) Fluoroplastic

• 5) Edge reinforcement Glassfabric polyurethane

coated

Movements• Axial 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

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)

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)

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

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

Tabbed bolster

Enables the bolster to stay into position

May also be pinned to the frame

Clamping methods

CLAMP BANDS CLAMP BARS AND FASTENERS

(Bolts, Nuts, Washers)

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

Very simple Low •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

Simple High •Longer E clamps may be used to keep heat away from the bolt

Clamping methods

Clamping methods

• Clamping using « G » clamps

• Used for belt type expansion joints

• No need for drilling

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

Prior to installationPlease 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

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

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

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 layerIf these sign appear you should contact the expansion joint manufactuer immediately
