ABSTRACT:
A flexible expansion joint suitable for connecting the spaced ends of two conduits which convey relatively hot fluid and solid particle streams and which expand and contract generally axially toward and away from each other with some lateral motion as well. The joint includes frame members connected to the ends of the conduits extending outwardly from the conduits with horizontal portions spaced from the conduits. The joint also includes one or more layers of flexible belt-like material resting upon the horizontal portions and fastened thereto. The joint also includes a pair of baffle-like members attached to each conduit, extending interiorly and preferably bridging the space between the ends of the conduits.
