Rectangular Fabric Expansion Joint

November 20, 2000

Rectangular Fabric Expansion Joint
The photograph above shows a rectangular fabric expansion joint in the final stages of assembly. The fabric “belt” is being attached to the metal frames. These expansion joints are inserted in metal ducts that carry hot gases at low pressures. Layers of different materials are selected to make a “belt” which will function at the high temperatures required.
