The main feature of SMO 254 Flanges is their outstanding resistance to pitting and crevice corrosion, which makes them suitable for aggressive chloride-bearing environments. Due to the high molybdenum content, these flanges are often referred to as a “6% Moly Grade.” They are strong, durable, and maintain excellent performance under fluctuating temperatures and high-pressure applications. Their ability to provide a cost-effective solution compared to nickel and titanium alloys adds to their demand.
SMO 254 Flanges are extensively used in industries where resistance to seawater and other chloride solutions is critical. They are a preferred choice in marine engineering, desalination plants, offshore oil drilling, chemical processing, and pulp & paper production. Their superior strength and corrosion resistance make them ideal for use in pressure vessels, heat exchangers, condensers, and petrochemical processing units.
These flanges are manufactured strictly in accordance with ASTM B366 and ASME SB366 standards. The production process ensures adherence to international quality norms, delivering products that guarantee high reliability and long service life. Precision engineering, quality raw materials, and advanced technology are combined to produce flanges that meet customer-specific requirements in terms of size, shape, and specifications.
