The components of the flexible apparatus are sealed or welded one to another such that it is fluid tight.

Abstract: An expansion joint for connecting pipe ends includes a fluorocarbon polymer tube having a reinforcing fabric embedded within it. The ends of the tube have radially extending flanges which are adapted to be in sealing relationship with the pipe ends. The tube has an annular arch spaced between the tube flanges. Metal stub ends having a radially extending flange at one end are in abutting relation to the tube flanges, thereby providing support and improved sealing from the otherwise flexible tube flange. A rubber backing is fastened to the fabric embedded in the tube. A back-up ring having peripheral fastener apertures is disposed about the tube at each end of the tube. The tube flanges are compressed between the back-up ring and pipe flange when the latter two are bolted together. A washer, spaced between the backup ring and rubber back permits the ring to be rotated about the tube to allow alignment of peripheral ring fastener apertures with corresponding fastener apertures in the pipe flange.

Abstract: An expansion joint and a fabric which may be used in connection therewith are disclosed. The expansion joint and fabric are particularly suitable for joining conduit sections through which high temperature, highly corrosive gases are conveyed, such as flue gases in a power plant. The fabric material includes a pair of foil-fabric composites in which a metallic foil is bonded to a high temperature resistant material, such as glass cloth. Between the two foil-fabric composites is a fluid impervious barrier preferably comprising an inner metallic foil of alloy material. The foil-fabric composites are stiffer than the high temperature resistant material alone, and this limits the motion and flexibility of the expansion joint to such an extent that the inner foil is not crumpled and damaged during use and handling. At the same time the stiffening is not so great that the ability of the expansion joint to accommodate relative movement between conduit sections is substantially affected.

Abstract: The joint is divided circumferentially into a series of sections which are symmetrically arrayed about the axis of the conduits and interconnected by generally axially extending pleats which make it possible for the joint to accommodate to lateral deflections of the conduits at a lesser dimension axially of the joint than that heretofore required by the diametral dimension of the joint.

The joint comprises inner and outer covering layers of elastomeric material and a body which includes at least one layer of a bias-cut fabric and at least one outer supporting layer formed of a helically-wound strip of elastomeric material with a plurality of parallel reinforcing strands running longitudinally through the strip. The joint is formed in a shallow or flowing arch configuration which does not trap particulate materials in a fluid stream, and obviates the need for a filler piece.

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.

Abstract: An elastic pipe-connecting component for pipes or pipelines or the like, comprises an elastic sleeve with flanges at each end and an annular expansion bulge in its midportion. In its undeformed condition, there is a cylindrical section on each side of the bulge, between the bulge and the portion of the component that is clamped to the pipe or pipeline. These exposed cylindrical portions are adapted to expand outwardly, to form two additional bulges, upon the imposition of pressure. To this end, they are reinforced with fibers of glass or steel or high strength synthetic, which are disposed at an angle to the axis of the component, of less than 55.degree.. A desirably long component is thus provided, from a minimum of material.

Abstract: An effective seal is provided which fulfills the requirement for a trouble free joint, particularly "V" band joints which are dependent on accurately controlled tube end flanges. Rolled sheet metal flanges are particularly subject to excessive leakages due to deformation during handling and installation. The normal tendency to stop leakage on any joint is by additional torque of the coupling. With the rolled sheet metal flanges, this causes additional deflection of the flange and aggravates the leakage problem rather than reducing it. Furthermore on aircraft environment systems leaks are extremely difficult to pinpoint and time consuming to repair.
