Duct Expansion Joints

Duct Expansion Joints

Duct Expansion Joints are designed to handle hot air or gases in industrial duct work, as well as those generated by power plant and pollution control equipment  (BUS DUCT EXPANSION JOINTS). They are custom constructed of rubber and fabric to absorb thermal movements and vibration in duct work and to aid in the elimination of noises caused by scrubber equipment and mechanical dust collectors.

Mighty-Span is capable of handling any combination of large movements which might occur in a ducting System due to thermal expansion. Mighty-Span creates almost no load on damper and fan interfacing flanges thus providing much needed protection in these critical areas. A wide range of elastomers and fabric substrates is available to provide maximum resistance to corrosion and high temperature capabilities.

Configurations

Square, rectangular or round shapes can be produced in almost any size. Standard construction is "U" shape with a 9 inch flange (other face-to-face dimensions available). Arch shapes also available. Body thickness of this one-piece molded joint is a nominal 5/16 inch. Extra liners are usually not required, but may be ordered if necessary.
