Fabric pipe 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. The fabric belt may need to be replaced periodically.
Fabric Expansion Joints are non-metallic duct expansion joints that provide stress relief for piping and ducting systems by absorbing thermal growth and shock, isolating mechanical vibration, and allowing for misalignments.Fabric expansion joints are precision engineered specifically for your application.
duct expansion joints are custom engineered to handle low pressure (Â±3 psig) applications with temperatures ranging from -100Â°F to more than 2000Â°F.
