Abstract
Many utilities in the United States have installed flue gas desulfurization (FGD) units as a result of the Clean Air Act. These units are similar to chemical plants, generally using an aqueous lime or limestone mixture to absorb the sulfur dioxide present in the flue gas. The equipment used to contain the flue gas is subject to severe corrosion due to sulfurous and sulfuric acids.
Resista-Clad (TM) Plate offers a reliable, cost-effective solution to these severe corrosion problems for retrofit or new construction. Resista-Clad Plate utilizes a patented technology to weld-bond thin gauge (0.5 to 2.0mm) corrosion resistant materials such as titanium, nickel based alloys, or stainless steel to relatively thick (1.6 to 25.4mm), significantly less expensive, carbon steel. Clad plate produced by this technology has been used and proven successful in hundreds of demanding applications in the chemical process industries since the development of the process in 1975.
