2205 duplex stainless steel blind flanges, as a core sealing component in industrial piping systems, are widely used in demanding applications such as petrochemicals, seawater desalination, and mining due to their dual characteristics of corrosion resistance and high strength. The products manufactured for this project strictly adhere to international industrial standards (such as ASTM A182), and have undergone rigorous testing during the manufacturing process, including compositional analysis, mechanical property testing, and corrosion resistance verification. The specific ratio of chromium and molybdenum elements ensures corrosion resistance in the tropical, humid environment of Côte d'Ivoire and in contact with industrial media, while the duplex microstructure provides impact strength far exceeding that of ordinary stainless steel, making it suitable for the high-load operating requirements of the local project. The 2205 duplex stainless steel blind flanges shipped in this consignment will be used in the end-of-pipe sealing systems of local industrial facilities – their weather resistance and durability will effectively reduce future maintenance costs and support the long-term stable operation of the project.
