DESCRIPTION

UNAFLEX® "MIGHTY-SPAN" Style 600 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.

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. Let UNAFLEX®  assist you in selecting the "MIGHTY-SPAN" product for your application.

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.

  1. Lateral Elongation= 2 lbs. per foot of perimeter per 1/16" of movement. For example: 2' x 2' I.D.= 8' perimeter deflection= 1" = 16/16.         2 lbs. x 8" x 16"=256 lbs.
     

  2. Axial Compression = 2.2 lbs. per foot of perimeter per 1/16" of movement. For example: 2' x 2' I.D. = 8' perimeter deflection = 1" = 16/16.
    2.2 lbs. x 8" x 16" = 282 lbs.
