High quality stainless steel wire, supplied by AB Sandvik Steel, is helping to produce optimum dust removal efficiency for electrostatic precipitators used in industrial flue gas cleaning.
Sandvik's wire is formed into extension springs. Extended in the precipitators, they act as discharge electrodes, for example in equipment supplied by ABB Environmental Systems AB. When electrically charged, the precipitators collect particles in the gases to be cleaned. For many years, this type of discharge electrode has been preferred for many applications because of its excellent electrical properties, which ensure high particle collecting efficiency.
Long established but effective technology has seen the development of discharge electrodes focus on the surface quality and performance of the stainless steel wire used for the electrodes. Hostile environments place high demands on the level of corrosion resistance of the material necessary to minimise the risk of stress corrosion cracking caused by the presence of chlorides.
Sandvik Steel supplies a 20 percent chromium 25 percent nickel stainless grade, designated 904L (Sandvik 2RK66) a steel recommended for extremely corrosive conditions. A key benefit to ABB Environmental Systems of the Sandvik supply route is access to Sandvik's extensive R & D facilities for testing and materials development.
