Abstract

An expansion joint spring clip can eliminate flutter, pulsations and reverse bending on non-metallic fabric flue duct expansion joints. The expansion joint spring clip can hold the expansion joint in a fixed arch such that it can still perform its function with regard to accommodating the ducting system movements. The expansion joint spring clip allows the entire width of the non-metallic expansion joint to retain its position during start-ups, downloading and during full or partial boiler, kiln, furnace loads and the like. The expansion joint spring clip can be installed in the existing geometry of an expansion joint by producing an arch while not damaging the expansion joint after being installed. The expansion joint can still accommodate axial and limited lateral movements, allowing the expansion joint to perform its function.
