Basic Design Configurations
Integrally Flanged “U” Type
The single layer belt can be provided either as a fully hand moulded UNAFLEX® “Mighty Span” Style 600 Elastomeric expansion joint or a continuous moulded corner THERMA-FLEX Style Elastomeric or Fluoropolymer joint. Style 600 joints are available with or without various arch profiles moulded into the body. The service temperature is limited by the material rating. U-type joints are used frequently in fan applications due to their minimal hardware requirements and vibration/sound attenuation.
Flat Belt Type
Available in single layer or composite belts mounted parallel to the duct on attachment frames. The frames may be either bolted to mating flanges or welded directly to the ductwork. See above for standard frame profiles. Flat belt types are commonly used in high temperature applications and where a setback is recommended or required or required. This configuration can be designed to readily accept various accessories such as telescoping or floating flow liners, cavity pillows and fly ash seals.
