Resista-Clad Plate for Flue Gas Desulphurisation

The increasingly severe environments modern FGD technology is subjected to, increase the importance of construction materials which are selected for such applications. During the last three decades, the use of corrosion resistant metals to prevent the severe corrosion problems present in FGD units has become commonplace. One problem that may be associated with using metals, assuming the correct metal has been chosen, is the method of attachment. There are three commonly used methods of attachment; 1) resistance welded clad plate, 2) plug welding/wallpapering, and 3) roll bonding. The second and third methods of attachment can be relatively expensive. The first method, resistance welded clad plate, offers a cost effective solution that has been proven with over 1,000,000 s.f. (93,000 m²) of actual “in service” FGD installations since 1984.
