Monel Flanges Manufacturer

Monel Flanges are made up of a nickel copper alloy that is very much resistance to acids and reducing materials. There are different grades of Monel such as monel  400 and K500 which have different chemical composition. The Alloy K500 Pipe Flanges have 63% nickel with 28% copper and carbon, manganese, silicon, sulfur and iron. The iron component in the monel K500 is much lower than that of monel 400.

The specification of these flanges is ASTM B564. These flanges range in size from 1/8 inches to 48 inches. The Monel UNS N04400 Flanges also come under different standards such as ASTM, ASME, ANSI, DIN and all other international standards with varying dimensions. The dimensions of the flanges determine the pressure classes. The flanges also come in different types such as the Alloy 400 Weld Neck Flanges. It has a welded neck which is used to hold the pipe and weld together. There are other types such as slip on flanges, blind flanges and orifice flanges. The flange face differs as flat face, raised face and ring type joint face as well. The Monel Slip On Flange is most useful with seamless pipes. The seamless pipes can easily slip onto the flange and reach the precise connection location. The ASTM B564 Monel 400 Lap Joint Flanges and other flanges can also come as threaded, forged, screwed or plate flange types. Each different type is used differently. The monel 400 flanges have 550MPa minimum tensile strength and 240MPa minimum yield strength where the Monel K500 Flange has 110MPa minimum tensile strength and 790MPa minimum yield strength. The melting point of both grades is at 1350 degrees Celsius.
