A cylindrical flexible joint unit for interconnecting a hot gas duct of circular cross-section to a further duct structure of circular cross-section. The flexible joint unit comprises an inlet annular flexible wall structure for connection to the hot gas duct and an outlet flexible annular connector. Heat insulating material is retained between the annular wall structures and an outer flexible annular membrane. The inlet wall structure has a cylindrical inner sleeve and an annular step connecting flange secured about an outer surface of the sleeve. The inner sleeve has a duct connecting end and a free end. The step connecting flange has a short transverse connecting wall and an elongated annular spaced wall section extending from the connecting wall, and disposed substantially parallel above the outer surface of the inner sleeve toward the duct connecting end to define an air gap therebetween. A membrane connecting bracket extends above a free end of the wall section to connect with a side edge of the annular membrane thereabove. The free end of the annular sleeve is displaceably disposed with relation to the outlet flexible connector. The annular connector has a duct connectingz end for connection to the duct of another structure, and has an opposed side edge of the annular membrane connected thereto. |
