Expansion Joints

In air ductwork systems, dynamic stresses caused by fan vibrations, temperature fluctuations and other sources can lead to premature equipment failure. Expansion joints or flex connectors provide flexibility in duct when connected to rotating equipment to alleviate these stresses. In specifying expansion joints for an air system, consideration must be given to:

• Axial, transverse and torsional movement
  
• Temperature of the airstream
  
• Noise levels
  
• Abrasive nature of particulate in the airstream
  
• Corrosive nature of the airstream

Expansion joints are often required in industrial applications in facilities such as:

• Petro chemical plants
  
• Lime and cement plants
  
• Paper mills
  
• Manufacturing plants

Expansion joint applications range from small industrial fans to utility grade expansion joints used in pollution control ductwork.
