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:

  1. OUTSIDE LAYER/COVER
    Our EFLEX™ Fluoroflex single layer belt beside with the highest temperature capability (600°F) for a gas seal layer.
  2. TFE LAYER
    Additional vapor barrier can be provided for applications, which may cycle thru dew point.
  3. 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”.
  4. 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.
  5. 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.
  6. 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.
