Alloy 20 Flanges Supplier
Alloy 20 is a highly corrosion-resistant material that finds extensive use in various industrial applications, particularly in aggressive environments where conventional stainless steels would corrode. Alloy 20 Flanges are essential components in pipelines and equipment used in these settings. These flanges are designed to ensure leak-free connections and structural integrity in demanding conditions.
Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium alloy with added molybdenum and copper, making it exceptionally resistant to sulfuric acid, phosphoric acid, and chloride solutions. The combination of these alloying elements provides excellent corrosion resistance, making it a popular choice in industries like chemical processing, petrochemical, pharmaceutical, and food processing.
Alloy 20 flanges are manufactured in various types to accommodate different piping and equipment requirements. The most common types include slip-on flanges, weld neck flanges, socket weld flanges, blind flanges, and lap joint flanges. Each type has specific applications and installation methods, ensuring a secure and reliable connection.

These flanges are designed to meet various industry standards, such as ASME B16.5, ASME B16.47, and MSS-SP44. They come in different sizes and pressure ratings to match the specific requirements of a given project. Alloy 20 flanges are available in Class 150, 300, 600, 900, 1500, and 2500, which define their pressure-holding capacity.
When selecting Alloy 20 flanges, it’s crucial to consider factors like the working environment, temperature, pressure, and the type of fluid being transported. This helps in choosing the right type and rating to ensure the safety and efficiency of the system.
Alloy 20 flanges offer several advantages. Their resistance to corrosion, especially in acidic and corrosive environments, makes them ideal for industries that handle corrosive chemicals. They are also easy to machine and weld, simplifying installation and maintenance processes.
Proper care and maintenance are essential for Alloy 20 flanges to ensure their longevity and reliability. Regular inspections and cleaning can help prevent corrosion and maintain their performance.
