Inconel 690 Flanges Manufacturer, Inconel 690 Flanges, Inconel 690 Flanges in India, Inconel 690 Flanges in Mumbai
Inconel 690 Flanges are high-performance nickel-based alloy flanges designed for superior resistance to high-temperature oxidation and corrosion, particularly in harsh chemical and nuclear environments. These flanges are commonly used in heat exchangers, steam generator tubing, chemical processing equipment, and thermal power systems. Labdhi Metals, a trusted manufacturer, stockist, and exporter, offers a comprehensive range of Inconel 690 Flanges in various pressure classes and sizes, suitable for demanding industrial applications.
The high chromium content (27–31%) in Inconel 690 Flanges significantly enhances their ability to resist corrosion caused by oxidizing acids, chlorides, and other aggressive media. The alloy maintains mechanical integrity even at elevated temperatures, making it suitable for continuous use in environments reaching up to 1000°C. Labdhi Metals provides different types of flanges such as weld neck, blind, slip-on, socket weld, threaded, and lap joint, available with raised face (RF), flat face (FF), and ring type joint (RTJ) sealing surfaces.
Inconel 690 Flanges supplied by Labdhi Metals are forged and machined to exact tolerances using state-of-the-art manufacturing facilities. These flanges undergo strict quality control checks including ultrasonic testing, hydro testing, PMI (Positive Material Identification), and third-party inspections to ensure their compliance with international standards such as ASTM B564 and ASME B16.5/B16.47. Clients also receive full traceability documentation, test certificates, and packing per global export norms.
The mechanical properties of Inconel 690 Flanges ensure high tensile strength, good ductility, and excellent resistance to thermal fatigue and creep. This makes them ideal for use in power generation, petrochemical processing, nuclear reactors, and marine applications. Their excellent weldability also simplifies installation and long-term maintenance. Labdhi Metals is capable of offering both standard and custom flange solutions as per client drawings and application-specific needs.
