Super Duplex Flanges Manufacturer In India | Astm A182 F53, F55 & Asme B16.5 Flanges

Riddhi Siddhi Metal Impex is a leading Super Duplex Flanges Manufacturer providing high performance flanges to offshore platforms, marine systems, chemical processing plants, desalination units, oil and gas facilities and industrial piping networks. They are produced using high-quality alloys including UNS S32750 and UNS S32760 giving them high tensile strength, excellent corrosion resistance, high pitting strength, and high durability in aggressive chloride-rich environments. Their two-phase microstructure has the advantage of austenitic and ferritic stainless steels and are applicable to the high-pressure industrial applications where long-service life and excellent mechanical behavior is needed.

Super Duplex Flanges can be sourced by the industrial procurement teams and project contractors using a reliable B2B Platform that will provide customized dimensions, pressure classes and flange configurations. These flanges are produced as per international standards and subjected to high quality tests to be sure of high working conditions under extreme conditions. Their high stress corrosion resistance against cracking and their resistance against seawater corrosion as well make them a choice in critical industrial structures where safety, efficiency, and durability is a prerequisite.

Super Duplex Flanges find wide use in industries that demand high-level resistance to corrosion, erosion, and high pressure service conditions. They are ideal in offshore buildings, subsea equipment, petrochemical plants, and marine engineering, as they are very strong to mass and very resistant to seawater assault. In corrosive chemical environments where the best resistance against oxidizing and reducing media is needed, Hastelloy B3 Flanges are in common use in chemical reactors, pharmaceutical processing systems, and customized industrial applications where the reliability of the material used and corrosion resistance is of utmost importance.
