On the Economic Benefit of Using Components Internally Clad with Corrosion Resistant Alloys

Abstract

Given the highly corrosive environments which have to be handled in the geothermal industry and benefits of reduced unscheduled downtime when are used, operating cost savings would be anticipated if more use was made of CRAs. By utilising clad products much less weight of expensive corrosion resistant alloy is needed and potential capital costs savings can be made. This paper describes the range of production routes available for manufacturing clad products and shows that is possible to engineer almost any item which might be required clad form. Successful application of clad products in other major industries over the last 40 years should encourage their increasing application in the geothermal industry
