1 WELCOME

2 The company Origins back in 1923: FERODO / VALEO First expansion joint in 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

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

5 Our typical customers –Power generation Fossil fired plants Gas turbine plants Cogeneration plants Nuclear plants –Cement plants –Refineries Petroleum Chemical –Steel and aluminium –Waste incineration –Pollution control and flue-gas cleaning –Pulp and paper –Food processing –Heating and ventilation –Sugar refineries –Engineering Companies

6 Fabric expansion joints Air and flue gas duct systems Filtration, de-dusting, ventilation, drying… Boilers Casing, heater… Gas turbines Gas turbine exhaust, diverter, HRSG, chimney Furnaces, Cyclon tower, Clinker

7 Design considerations Type of plant Location in plant Medium Air, flue gas, etc… Chemical corrosion Loaded with dust Pressure Positive or negative Pulsations or not Temperature Temperature of medium Design temperature Operating temperature Ambient temperature Peak temperature Movements Vibrations Duct geometry Dimensions, insulation

8 Main configurations Belt type U type or Flanged Arched type Bellow type

9 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

10 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

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

17 Various clamping methods Method of clamping Ease of installation or replacement CostSuitability Warm drive clampVery simpleLow Used for small size expansion joints Clamps bands with screw or bolt fixing Very simpleLowCircular shape & low pressure only Clamps must be split into several segments Clamp bars with bolts and nuts SimpleMediumPre-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 SimpleHighLonger E clamps may be used to keep heat away from the bolt

18 Clamping methods

19 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 manufacturers 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
