ABSTRACT:
A coupling apparatus and method for coupling two duct sections together to form a joint therebetween. The apparatus includes a catcher ring component formed coextensive with the edge of one section of duct, and a catcher finger component formed coextensive with an edge of the other section of duct being coupled to form the joint. The catcher finger component includes a catcher finger which is longitudinally aligned with a flange of the catcher ring, and that protrudes inwardly into its associated section of duct. In the event of a failure of a main clamping assembly disposed over an outer periphery of the two duct sections at the joint, the catcher finger and flange engage to limit separation of the two sections of duct to only a controlled, limited degree. This protects other subassemblies and components positioned closely adjacent the duct from any damage that might result from separation of the two duct sections, including exposure to high temperature and pressurized air.
