Duplex Steel Flanges are made up of various duplex steel materials. R.C. Metal Corporation is a leading manufacturer and supplier of the Duplex 2205 Flanges in various dimensions and shapes. The 2205 is the most used grade of the duplex steel grades. There are super duplex and lean duplex grades in addition to this standard duplex grade. The flanges made up of the duplex steel belong to ASTM A182 F51 UNS S31803 and others. The ASTM A182 specification covers components for pressure vessel grade applications. These Duplex flanges can be used in high pressure and high temperature services such as the boilers, condensers, heat exchangers, power generation plants and in petroleum industrial applications as well.
The Duplex Steel Flanges manufacturer in india can be forged, welded, threaded or screwed. Each different type has its own advantages. There are different grades of duplex steel that have different mechanical and physical properties due to the different chemical composition. The ASTM A182 F60 Flanges are high performance, cost effective and long lasting flanges. There are different face types such as the ring type joint flanges, flat face flanges and raised face flanges.
The F60 UNS S32205 Flanges can be used with welded pipes as well as seamless pipes. The application requirements mandates which flange is to be used. The dimensions vary in terms of wall thicknesses and the nominal bore sizes. The nominal bore sizes range from ½ inches to 48 inches in most cases. There are different types and grades such as the ASTM A182 F51 Flange. As a leading supplier, we manufacture all grades, all types and all shapes for flanges such as the Duplex Blind Flange. Please contact us for your orders in the Duplex stainless steel flanges.
