• Process duct work - Wikipedia

    Process duct work conveys large volumes of hot, dusty air from processing equipment to mills, baghouses to other process equipment. Process duct work may be round or rectangular. Although round duct work costs more to fabricate than rectangular duct work, it requires fewer stiffeners and is favored in many applications over rectangular ductwork.

    Depending on its application, process ductwork can be either rectangular or round. Most cement plant ductwork, for example, is round because it requires fewer stiffeners. Power plant ductwork, on the other hand, is usually rectangular and incorporates heavy stiffeners every 2” to 6” to minimize vibrations. HVAC Ductwork

  • Process duct work - WikiMili, The Best Wikipedia Reader

    Round ductwork. The majority of cement plant process ductwork is round. This is because the round duct shape does not bend between circumferential stiffeners. Therefore bending stiffeners are not required, and round ductwork requires fewer and lighter intermediate stiffeners than rectangular ductwork.
