Fabric Expansion Joint

As described by Fluid Sealing Association-USA, “Non-MetallicFabric Expansion Joints are flexible connectors designed to provide stress relief in ducting systems by absorbing movements caused by thermal changes. They also act as vibration isolators, shock absorbers and in some instances to make up for minor misalignment of adjoining ducting or equipment.” Fabric Expansion Joints are typically designed for ducts where pressure is know, not more than 3 psi (2000 mm wc) and temperature up to 1000oC. However, for higher temperatures, duct itself needs to be internally insulated.
