Single Layer Flexible Connections – All Types:
- Single Layer, or “ply” Flexible connections are designed to provide: Vibration isolation, absorb expansion, compensate for misalignment in ductwork and reduce noise breakout when using flexible materials having dedicated noise attenuation properties.
- Available in the following standard geometries:
- “Circular Flat Flanged” (C.F.F.) - Circular with “plain ends” suitable for “Jubilee Clip” type installation.
- “Rectangular Flat Flanged” (R.F.F.) - Square / rectangular with “plain ends” suitable for backing flat installation.
- “Circular Angle Flanged” (C.A.F.) - Circular with flanged ends at 90 degrees to the body suitable for steel backing flanges.
- “Rectangular Angle Flanged” (R.A.F.) - Square or rectangular with flanged ends at 90 degrees to the body suitable for steel backing flanges.
- Can also be manufactured as tapering and / or transitioning from circular to rectangular geometries.
- Can be supplied pre-punched to match clients existing ductwork flanges or “plain flanges” for drilling during installation, where specific hole centres are unknown.
- Fire rated materials available for specific applications.
- All related steelwork can be specified, designed and manufactured in-house, including:
- Steel Backing Flats / Flanges, Steel Inner sleeves to protect the Flexible Connection from abrasive particles or high velocity gasses / buffeting.
Other Types of Flexible Connections available, (the majority of which are coated in-house):
Type B: Neoprene Coated Glassfabric.
Type C: Specialist materials having Acoustic properties, chemical resistance or insensitive to buffeting.
