Stainless Steel Flanges are widely used piping components designed to connect pipes, valves, pumps, and other equipment in various industrial piping systems. These flanges are known for their excellent corrosion resistance, high mechanical strength, durability, and reliable performance under high-pressure and high-temperature conditions.
Stainless Steel Flanges provide easy access for inspection, cleaning, and modification of piping systems and are extensively used in oil & gas, chemical processing, power generation, petrochemical, marine, and industrial fluid handling applications.
Stainless Steel Flanges are manufactured using high-quality forged materials conforming to ASTM standards. The most commonly supplied grades include ASTM A182 F304, ASTM A182 F316, ASTM A182 F310, ASTM A182 F321 and ASTM A182 F347, offering excellent resistance to corrosion, oxidation, and elevated temperatures.
