Abstract
A duct assembly for transporting pressurized fluid therethrough. The assembly includes first and second duct sections. Each of the duct sections has sides extending between opposite ends. Each of the sides join an adjacent side and has a flange extending laterally outward from each end. The first and second sections are positioned in end-to-end relation so that the flanges extending outward from one of the ends of the first section face the flanges extending outward from one of the ends of the second section to define flange pairs. The assembly also includes a plurality of connector pairs. Each of the connector pairs are positioned at one of the ends of the duct sections. Each of the connector pairs includes a first connector spanning adjacent flanges of the first duct section and a second connector spanning adjacent flanges of the second duct section. The first and second connectors are positioned on opposite faces of an adjacent flange pair so the flange pair is positioned between the first and second connectors. Further, the assembly includes fasteners extending through one of the connector pairs and one of the flange pairs to connect the flange pairs. In addition, methods and apparatus for use in making the duct assemblies are disclosed.
