Inconel 718 Flanges are high-performance components used in piping systems. These flanges are primarily used for their extreme temperature resistance and strength retention, even at cryogenic temperatures. Alloy 718 flange is a nickel-based alloy that contains chromium, iron, niobium, molybdenum, tantalum and other elements. The most common type of Nickel Alloy 718 Flange is the Weldneck Flange which has a neck projecting from the hub diameter of the flange that makes it suitable for welding into a system using conventional methods. This flange type provides excellent leak resistance due to its welded connection and can be connected without bolts or gaskets while creating an incredibly strong joint. Inconel 718 Alloy flanges are a type of weld neck flange made from nickel-based Inconel 718 alloy. , UNS N07718 provide superior corrosion resistance due to high chromium, molybdenum, and niobium content levels. These chemical elements offer strong protection against seawater and chloride-induced corrosion and excellent temperature stability up to 1000°F (538°C). The weld neck design makes them particularly useful in critical applications where stress concentration must be minimized. Overall, they are an ideal choice for many corrosive environments.

 

Jinie Technology (Jiangsu) Co., LTD is one of the leading Manufacturers, Supplier and Exporters of ASTM B564 Inconel 718 Flanges. These products are manufactured under the supervision of our experienced professionals using high class raw materials. We are offering Inconel 718 Flanges to our client at a very reasonable range of prices. Inconel 718 flanges is a nickel chromium molybdenum alloy with high strength at elevated temperatures, combined with outstanding corrosion resistance. Inconel 718 flanges has a corrosion resistance to many environments. In mild environments such as atmosphere, fresh water and sea water, neutral salts and alkaline media there is almost no attack. In more aggressive media nickel and chromium resist oxidising attack, while nickel and molybdenum resist reducing environments. Molybdenum provides exceptional resistance to pitting and crevice corrosion, and niobium stabilises against sensitisation and intergranular corrosion. There are two speciality in Inconel 718 flanges that immediately stand out are its resistance to oxidation and its scaling at very high temperatures. This makes Inconel 718 inlay flange vastly superior to other alloys, even ones that are made for high temperatures and varying heating and cooling conditions. The high levels of Molybdenum in Inconel 718 Orifice flanges make it resistant to pitting & also allows the alloy to function in extreme conditions. Inconel 718 Long welding neck flanges has a good fatigue strength and stress-corrosion cracking resistance to chloride ions, which is why oxidation and corrosion is so rare. We offer these Inconel Alloy 718 Flanges in custom-made sizes and thicknesses, as per the exact demands of our esteemed clients.
