Alloy 31 Application:

  • Components for flue gas desulfurization (FGD) plants

  • Plants for the production of phosphoric acid via the wet digestion process

  • Pipes and heat exchangers for sulfuric acids contaminated with chlorides

  • Pipes containing ocean water and brackish water, condensers and chillers

  • Pickling plants for sulfuric acid as well as nitric-hydrofluoric acid

  • Treatment of sulfuric acids from waste

  • Evaporation and crystallization of salts

  • Components for the cellulose and paper industry

  • Digestion of ores, e.g. in HIPAL (high-pressure acid leach) plants for the digestion of laterite ores

  • Mineral oil production and refineries

  • Organic acids and ester synthesis

  • Strain-hardened transport and feed pipes as well as slicklines, wirelines and flowlines in the transport of oil and gas

  • Marine scrubber / ship diesel scrubber
