Non Metallic Expansion Joints

Fabric expansion joints are often used in ducts which carry hot gases at low pressures. The major design parameters are the temperatures and flow rates of the gases and the amount and abrasiveness of solids suspended in the gases. Layers of different fabrics insulation can be combined to accommodate the temperatures and pressure in the system. For handling gaseous media, which is likely to adversely react with most metals, fabric compensators can be an optimal solution.The fabric belt may need to be replaced periodically.
