The assemblies may include fabricated elbows, tees, and straight sections of duct work, in carbon steel or stainless steel, and in diameters of 42″ or larger. The duct sections can include fabric or metallic expansion joints and can be rectangular or round. U.S. Bellows can also provide specialized pipe supports and spring hangers for large diameter duct work.
