Super Duplex 2507 Flanges: Types and Uses

Super Duplex 2507 Flanges are used in desalination equipment, oil and gas industrial equipment, pulp and paper mill, flue gas scrubbing, chemical processing and in pressure vessels. The flanges are also used to connects pipes in high temperature services like heat exchangers. K.K. is a leading supplier and producer of Super Duplex 2507 Flanges in different sizes and scales.

The Class 150 Super Duplex S32750/ S32760 Flanges are used mainly because of their corrosion resistance and strength. The class 150 is a pressure class which is one of many pressure classes available such as 150 through 2500 and PN6 through PN64. The material is strong with 116ksi minimum tensile strength and 80ksi minimum yield strength.

The Super Duplex Stainless Steel S32750 Orifice Flange is used in applications that require extra corrosion resistance to chloride ion. The composition includes 25% chromium, 7% nickel and 4% molybdenum which give the tubes this corrosion resistance. The ANSI B16.5 Super Duplex UNS S32760 Blind Flange types range from ½ inches to 48 inches in nominal bore sizes. There are different types of flanges suitable for different applications.

Process and service water systems, ballast water systems, and desalinization plants utilize 2507’s resistance to chloride. Mechanical assemblies and infrastructure relies on Super Duplex 2507 flanges for their ability to withstand a high mechanical load in seawater. Super Duplex 2507 flanges are also used in offshore platforms, as well as oil & gas exploration and production to protect from seawater. Power industry flue-gas desulfurization systems and geothermal exploration units also rely on 2507 flanges.

The seamless pipes are fitted with precision in applications that need dimensional precision. The ASTM A182 Super Duplex S32750 Slip On Flanges are used to fit the seamless pipes. The flanges could be fitted by different methods such as bolting, welding or threading. The Super Duplex DIN 1.4410 Threaded Flanges are fitted with threaded pipes. The flanges often come with a female thread and the pipes with male threads. Sometimes the threaded flanges are welded for additional grip.

The Super Duplex SAF 2507 Socket Weld Flanges have sockets welded onto them and they are used to hold the pipes together. Unlike many other types of flanges, the ring type joint ASME SA182 Super Duplex S32950 RTJ Flange has two rings welded to the ends of pipes and act as a pair to hold the pipes in place.
