Rubber Expansion Joints

Rubber Expansion Joints

Let Uniflex assist you in selecting the right expansion joint for your application. Rubber Flue 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. 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. These expansion joints are capable of handling any combination of large movements which might occur in a ducting system due to thermal expansion.

Rubber Expansion Joints

Rubber expansion joints create 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.

Rubber expansion joints come in a multitude of stock designs and can also be custom manufactured for your specific application. Options include PTFE-lined, concentric reducing, eccentric reducing, filled arch, lightweight, and off-set configurations. Expansion joints can be designed to operate in up to 200 psi with temperatures up to 500 F in sizes from ½” up to 144”.

Configurations

Square, rectangular or round expansion joints 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.
