Labdhi Metals is a renowned manufacturer, stockist, and exporter of Duplex 2205 Flanges, supplying premium-grade flanges to clients across a wide spectrum of industries. Known for their excellent mechanical properties and corrosion resistance, these flanges are ideal for applications in offshore oil and gas, petrochemical plants, chemical processing, marine engineering, and desalination systems. Manufactured with precision and strict quality control, Labdhi Metals’ Duplex 2205 flanges provide superior durability and performance in aggressive environments.
Duplex 2205, classified as UNS S31803/S32205, is a nitrogen-enhanced duplex stainless steel alloy. It combines the beneficial qualities of both austenitic and ferritic stainless steels, offering high yield strength (nearly twice that of 304 or 316 stainless steel), excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. These properties make Duplex 2205 an excellent choice for flange manufacturing, especially where both mechanical performance and corrosion resistance are critical.
Labdhi Metals offers a wide range of Duplex 2205 flanges including Weld Neck, Slip-On, Socket Weld, Lap Joint, Blind, Threaded, and Long Weld Neck Flanges. These flanges are manufactured in accordance with international standards such as ASTM A182, ASME B16.5, B16.47, BS, EN, and DIN, ensuring compatibility and safety in piping systems. The flanges are available in sizes from ½” NB to 24” NB and pressure ratings from 150# to 2500#.
As a dependable stockist, Labdhi Metals maintains a ready inventory of Duplex 2205 flanges in various pressure classes and face types such as Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ). This extensive stock availability allows the company to meet urgent and bulk requirements for both domestic and international projects. Their state-of-the-art facilities also support value-added services like custom drilling, beveling, surface finishing, and coating.
