Ducting expansion joints
We offer flue duct expansion joints of several varieties including standard movement, maximum movement, and ultra-high movement types. The standard movement expansion joints are built to handle typical ducting movements and applications. This style offers maximum noise reduction and vibration control, and provides exceptional protection for duct systems, flanges, and equipment housings.
Maximum movement flue duct expansion joints are offer superior axial and lateral movement without pre-extension or pre-compression. It is perfect for applications in precipitator, scrubber, baghouse and stack, hot air or flue gas ducts. It is also ideal for FRP piping.
Ultra-high movement expansion joints are well-suited to positive pressure clean air systems, involving ultra-high axial compression and extension. This style has a high V-shaped arch that provide the highest axial movement in the industry while only exerting very low forces on flanges, ductwork, and equipment.
We have experience assisting customers from a variety of industries with a variety of applications. For instance, just some of the applications our duct expansion joints are often used for include scrubbers, emissions control, refuse incinerators, gas turbine exhausts, steam boiler systems, industrial furnace and chimney construction, fan connectors, air handling systems, and powder coating booths.
