Alloy 20 blind flanges are designed to provide secure, leak-proof closures at the ends of pipelines and pressure vessel openings, making them essential in applications requiring corrosion resistance and high strength. Tesco Steel & Engineering manufactures high-quality Alloy 20 blind flanges with precise machining and excellent surface finishes, ensuring long-term reliability in chemical, petrochemical, and pharmaceutical processing systems. The flanges are available in equivalent grades such as UNS N08020, 2.4660, WP20CB, AFNOR Z2NCUD31-20AZ, and EN NiCr20CuMo, ensuring compatibility with global standards for critical industrial projects.
The chemical composition of Alloy 20 typically includes 32-38% nickel, 19-21% chromium, 3-4% copper, 2-3% molybdenum, and small amounts of niobium, iron, and manganese, providing excellent resistance to sulfuric acid, chlorides, and general pitting and crevice corrosion. Tesco Steel & Engineering ensures each Alloy 20 blind flange meets strict quality standards, delivering dimensional accuracy, consistent mechanical properties, and resistance to corrosive environments. These properties make Alloy 20 blind flanges ideal for industries handling acidic environments, including chemical processing plants, pharmaceutical manufacturing, and food processing facilities.
