... Yeah. Let's go with that.”
Fabric Expansion Joints
Properly controlling thermal expansion within coal-fired power facilities is often achieved through the application of fabric expansion joints with the following characteristics:
- OUTSIDE LAYER/COVER
Our EFLEX™ Fluoroflex single layer belt beside with the highest temperature capability (600°F) for a gas seal layer.
- TFE LAYER
Additional vapor barrier can be provided for applications, which may cycle thru dew point.
- INSULATION LAYER
Needled fiberglass insulation thermally bonded to the EFLEX™ Fluoroflex substrate to protect from heat degradation. The bonding prevents separation and potential “Hot Spots”.
- REINFORCING LAYERS
Vermiculite coated fiberglass fabric acts as an insulator and increases expansion joint strength and durability. Wire mesh layers may also be added for increased durability and abrasion resistance.
- ADDITIONAL INSULATION LAYERS
The presence and thickness of this layer is determined by the system temperature to ensure that the heat transfer from the flue gas is reduced to a point less than the maximum temperature of the vapor barrier (600°F) and cover.
- INSIDE LAYER/ENCASEMENT
Close weave material binds the belt together, acts as an insulator and adds strength for handling and service. A metal flow liner is required in applications where there is abrasion.
Our fabric expansion joints are designed to optimize efficiency, performance, and reliability, incorporating a comprehensive engineering and manufacturing approach to meet your application critical requirements.
