SMO 254 Flange refers to a specific type of flange made from a high-performance alloy known as SMO 254, which is a super austenitic stainless steel with excellent corrosion resistance properties. These flanges are designed to connect pipes, valves, and other equipment in piping systems, offering a secure and leak-proof connection.
SMO 254 is highly resistant to both uniform and localized corrosion in various aggressive environments such as seawater, acids, and chloride-containing solutions, making it particularly suitable for applications in industries such as chemical processing, offshore oil and gas, desalination plants, and marine engineering.
