ABSTRACT:
An expansion joint for coupling conduits through which high temperature fluids are conveyed and accommodating severe vibrations and movements imparted to the conduits during the flow of fluids therethrough. The joint includes a pair of opposed frame sections for connection to the adjacent ends of the conduits being coupled. A connector of flexible fluid impervious fabric bridges and seals the space between the frame sections to provide a flexible and fluid-tight joint having both high heat resistance and high corrosion resistance. The ends of the fabric connector have portions, at corners of the connector, in which the fabric is folded back on itself to contribute to forming bloused corners. The bloused corners relieve stresses in the fabric connector to reduce the possibility of rupture.
