Inconel 690 Fittings are premium-grade nickel-chromium alloy components widely recognized for their exceptional resistance to high-temperature oxidation and corrosion in harsh chemical environments. These fittings are crucial in connecting and configuring piping systems that operate in extreme service conditions. Labdhi Metals, a prominent manufacturer, stockist, and exporter, provides a broad range of Inconel 690 fittings including elbows, tees, reducers, caps, and customized configurations designed to meet global industrial standards.
With a high chromium content (27–31%), Inconel 690 Fittings deliver superior performance in resisting pitting, crevice corrosion, and intergranular attack, especially in oxidizing and chloride-bearing environments. This makes them ideal for use in nuclear steam generators, petrochemical systems, and high-temperature industrial furnaces. Labdhi Metals ensures all fittings are manufactured using advanced forging and heat-treatment technologies, with tight dimensional tolerances and optimal surface finish.
Each fitting is carefully tested for its chemical composition, tensile strength, hardness, and dimensional accuracy. Whether it’s butt weld, socket weld, or threaded type, Labdhi Metals supplies fittings in both seamless and welded construction to match diverse application requirements. These fittings are known for their durability and structural integrity even when exposed to temperatures exceeding 1000°C.
Inconel 690 Fittings exhibit excellent mechanical properties and are well-suited for high-pressure, high-stress applications. They maintain their toughness and corrosion resistance under thermal cycling, making them an essential component in chemical processing, marine, and power generation industries. Labdhi Metals also provides test certificates, third-party inspections (TPI), and customized marking and packaging as per client requests.
