Steel duct assemblies have a wide range of uses. Refax, Inc. specializes in ductwork that transfers heavy wear/particulate air as well as gases through any system in any industry.
The downcomer is a series of ducts, elbows, and expansion joints that transfer dirty particulate heavy air and gas from the blast furnace to a process center for disposal and recycling. All ductwork, elbows, and expansion joints were made from formed Chrome Carbide Wear plate cut, formed, fit, and welded at our shop. All welds needed to be ASME gas tight with tolerances of +/- 1/16″. This project had various hold points for inspection with a full final inspection for welds, whole layout, expansion joint movement, and all other various critical items. Once complete we will coat each part with red oxide primer and deliver to our customer.
