Nickel alloy steel flanges are essential components used in piping systems to connect pipes, valves, pumps, and other equipment. These flanges are crafted from nickel-based alloys, renowned for their outstanding resistance to corrosion, high-temperature strength, and superior mechanical properties.
Nickel alloy steels, such as Inconel, Monel, Hastelloy, and Alloy 20, provide exceptional resistance to various corrosive environments, including acids, alkalis, seawater, and harsh chemical compounds. This corrosion resistance makes them suitable for applications in industries like chemical processing, oil and gas, marine engineering, and more.
These flanges retain their mechanical properties at elevated temperatures, making them ideal for use in high-temperature applications such as aerospace, power generation, and heat exchangers.
Nickel alloy steel flanges come in different configurations to suit various piping needs. Common types include weld neck, slip-on, socket weld, threaded, blind, and lap joint flanges, each serving different functions and installation requirements.
Due to their excellent corrosion resistance, high-temperature strength, and versatility, these flanges find applications across diverse industries like chemical processing, oil refineries, petrochemicals, pharmaceuticals, food processing, aerospace, and more.
There are several types of nickel alloy steels available, each with its unique properties tailored for specific environments. For instance, Inconel offers high strength and oxidation resistance, while Monel excels in resisting high-velocity seawater and acidic environments.
