These flanges are widely utilized in sectors where strength, corrosion resistance, and reliability are paramount. You’ll often find them in oil and gas pipelines, offshore platforms, petrochemical plants, desalination units, and chemical processing systems. Their design is particularly suited for handling aggressive media like chlorides, seawater, and acidic fluids. Thanks to their high mechanical strength, they allow for reduced wall thickness, which translates to weight savings and cost efficiency. Duplex Steel Flanges are also extensively used in marine, power generation, and water treatment industries.
