Fabric pipe expansion joints are often used in ducts that carry hot gasses at low pressures. The major design parameters are the temperatures and flow rates of the gasses and the amount and abrasiveness of solids suspended in the gasses. This fabric expansion joint utilizes a bulky flexible material, also called an Insulation Pillow, to shield against high temperatures protecting the belting material. Refractory is also used in the construction of this joint but is designed so that it does not interfere with movement. Our experienced engineers know that every element of this expansion joint plays a role in its rating for certain temperatures and the number of hours of operation.
