Nextgen Steel & Alloys is a noticeable organization that manufactures BS 4504 Flanges with the best quality. We manufacture various types of flanges like threaded, weld necks. Lap joint and plate. BS 4504 flange specifications are standard, size, type, process, pressure grade. We use cupro-nickel, duplex steel, nickel alloy, Hastelloy material to produce these flanges. Our BS 4504 flanges show mechanical properties like hardness, tensile strength, yield strength, and elongation. These flanges are suitable to use in low-pressure applications and harsh conditions. BS 4504 is a British standard for flanges.
We are supplying BS 4504 flanges having unique quality features like superior strength, excellent finish, high corrosion resistance, long-lasting life, and easy maintenance. Our BS 4504 Flanges are available in various pressure grades like PN6, PN10, PN16, PN25, and PN40. These flanges perform efficiently in stringent conditions like low-pressure applications such as in oil industries. BS 4504 flanges are highly resistive to stress corrosion cracking in chloride solutions. Also, these offer excellent resistance to corrosion and oxidation in any corrosive atmosphere. The unique mechanical and chemical properties of the flanges make them an ideal choice for high-temperature and heavy-duty applications. In instances where added corrosion resistance properties are required, buyers may order to get the surface of these flanges treated. Some of the more popular finishes of these flanges are included hot-dip galvanization, anti-rust finish, and zinc coating. Generally, treating the surface of BS 4504 Flanges to a hot-dip galvanization process yields much better results in terms of longevity, performance as well as corrosion resistance characteristics.
The uses & applications of the BS 4504 Flange are seen in industries like Heavy oil refineries, Nuclear power, and the Petrochemicals and acid production industry. Stainless Steel BS 4504 Flanges are also used as equipment in Offshore, Shipbuilding, Water systems, Natural Gas, Electric Power, Pipe Projects.
