Resista-Clad Plate

The increasingly severe environments in which modern FGD technology may be subjected to, weigh heavily on the materials of construction 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.

What is Resista-Clad Plate?

Resista-Clad Plate is a process that was invented in 1963 by Showa Entetsu Co., Ltd., a Japanese company. Resista-Clad Plate is a metal fabrication technique that uses a patented process in which a relatively expensive, thin sheet of corrosion resistant metal cladding is attached to an inexpensive substrate. The Resista-Clad Plate process is capable of cladding carbon steel to both weld compatible metals, such as nickel based alloys and stainless steels, and non-weld compatible metals such as titanium. This technique allows the cost effective use of both relatively high cost alloy metals and relatively low cost carbon steel.
