Using the right flue duct expansion joint is essential to preventing leaks, reducing noise and vibrations, maintaining operation, and lowering the risk of failure for ducting systems.  Our expansion joints are built to offer benefits including longer cycle life, improved movability, resistance to high temperatures and harsh chemicals, and reduced costs by eliminating the need for gaskets.

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.
