The Super Duplex flanges developed at Rajendra Pipe Fittings are renowned for their excellent strength and durability, making them ideal for various uses under many conditions. Rajendra Pipe Fittings supplies the Duplex Flanges with proper packaging to all major cities across the globe and prevents any kind of product degradation during supply. We cater for a wide variety of customers and aim to please them by giving our customers the highest price of the Super Duplex Flanges. Rajendra Pipe Fittings will supply bulk orders for these Duplex Flanges to foreign as well as national customers. For greater durability and applications, we manufacture the Duplex Flanges in various sizes and lengths. The Super Duplex Flanges are constructed of absolute dimensional precision and thus give tremendous strength and stability.
The Super Duplex Flanges are designed for applications in environments where the chloride-bearing cooling waters cause corrosion problems. These flanges are produced from the microstructure which contains almost equivalent properties of both stainless steel ferrite and austenite. These flanges contain high chromium rates which help them improve resistivity to acids and acid chlorides. The Duplex Flanges are particularly prone to corrosion at pitting. These Super Duplex Flanges produce around 25 percent chromium relative to 22 percent of the Duplex Flanges in general. The Duplex Flanges are significantly costlier and heavily alloyed flanges. The change in the amount of chromium often contributes to a rise in other elements, such as nickel. This lets the Flanges preserve the dual microstructure balance which makes them costlier. Those flanges are then used in an application where high resistivity to acid chlorides is needed.
The Super Duplex Flanges are reliable for applications where high general corrosion is needed against organic acids such as acetate and acetic formic acid. Through their applications, the industries utilizing the Duplex Flanges include heat exchangers, gas and oil factories, desalination facilities, and pipes through chloride-containing solutions manufacturing industries. The Super Duplex Flanges are also used in the automotive and service structures.
