Abstract
A ductwork system including a duct having a plurality of ducting panels joined together to define a flow passage extending therethrough, and the duct having structure for resisting damage thereto caused by a detonation within the duct. The structure for resisting damage can include an internal bracing within and extending across the flow passage of the duct to tie at least two sides of the duct together. For example, the internal bracing can be a reinforcement panel including a mounting frame with one or more elongated members extending from one side of the frame attached to a ducting panel to another side of the frame attached to an opposite ducting panel. Alternatively or in addition to the above structure, the duct can have structure for resisting damage that includes providing the duct with at least one curved or faceted side along an axial length of the duct.
