Monel 400 Flanges are premium-grade, high-strength, corrosion-resistant flanges made from a nickel-copper alloy known for its toughness and durability in extreme environments. These flanges offer excellent resistance to seawater, hydrofluoric acid, sulfuric acid, alkalis, and other corrosive agents, making them ideal for applications in marine, chemical, and petrochemical industries. Labdhi Metals, a leading manufacturer, stockist, and exporter, supplies Monel 400 Flanges in a wide variety of sizes, types, and pressure classes to meet the demands of global industrial applications.
The key advantage of Monel 400 Flanges lies in their ability to withstand both high pressure and high-temperature conditions while maintaining their structural integrity and corrosion resistance. The alloy is especially useful in environments where steel would typically suffer rapid deterioration. Labdhi Metals offers a full range of Monel 400 flange types including Weld Neck, Slip-On, Blind, Socket Weld, Lap Joint, and Threaded flanges. These are available in standards like ANSI, ASME, DIN, and EN, catering to a global clientele.
Labdhi Metals manufactures these flanges with precision machining and quality control processes such as ultrasonic testing, PMI testing, and hydrostatic testing. All flanges are produced as per international specifications including ASTM B564, ensuring consistent quality, accurate dimensions, and reliable mechanical properties. These flanges are commonly used in heat exchangers, offshore oil rigs, condensers, and marine equipment due to their long service life and low maintenance needs.
As a highly trusted exporter, Labdhi Metals ships Monel 400 Flanges to countries such as the USA, UAE, Germany, Saudi Arabia, South Africa, and Singapore. The company provides full traceability and documentation including Mill Test Certificates (EN 10204 3.1/3.2), third-party inspection reports, and test data to support project requirements. Flanges can be supplied in custom sizes and face types like RF (Raised Face), FF (Flat Face), and RTJ (Ring Type Joint) as per client specifications.
