Vishal Tube Industries is one of the leading Manufacturer of Super Duplex flanges in india, We are ISO Certified and best quality product Exporter of Super Duplex Alloy flanges in india. There is a low to negligible risk of the occurrence of carbide precipitation at grain boundaries during heat treatment due to the low carbon content of Super Duplex Alloy flanges. The Duplex is also extremely resistant to intergranular corrosion related to carbide, which is why several vendors consider using this stainless steel for a variety of operations. Super Duplex Lap Joint Flanges structure or duplicity in the stainless steel grade 2507 microstructure provides excellent resistance to chloride stress-related corrosion cracking or SCC for these components. Super Duplex Flanges provides superior properties, such as corrosion resistance and improved tensile yield strength, compared with duplex stainless steel grade 2205.


Super Duplex Steel Flanges are exposed at high concentrations to more substantial bases such as sodium hydroxide, and some etching and cracking are likely to occur at high temperatures, particularly with chloride-containing solutions such as sodium hypochlorite. When drilling for oil or gas, the challenging and dangerous conditions often encountered indicate that Super Duplex Alloy Flanges are the perfect material for the manufacture of vital components. The combination of power, corrosive resistance and also an ability to resist the harmful effects of pitting and crevice corrosion in such Super Duplex Orifice Flanges result in a life expectancy much in excess of that achieved by regular steels. Due to its low glare reflectance, Super Lap Joint Flanges is a new trend for airport roofing materials to prevent pilots from being blinded. In order to keep the roof surface close to ambient temperature, Super Ring Style Joint Flanges are often used for their properties that allow thermal reflectance. Super Flanges The presence of chromium, an intermetallic phase that can precipitate upon welding, can degrade Super Weld Neck Flanges. Super Duplex Steel flanges, despite their nature and use, can still be susceptible to corrosion, especially in corrosive environments.
