Duplex Steel Flanges are available in a wide range of pressure ratings and sizes, to meet the specific requirements of precise projects that call for the use of such types of Duplex Alloy WNRF Flanges. Stainless Steel Duplex Lap Joint Flanges have high energy absorption and low thermal expansion. Duplex Stainless Steel Flanges are available in a wide variety of flanges such as Duplex SS Weld neck RF Flange, SS Duplex Weld Neck Flanges, DSS Slip On Flanges, Duplex Spectacle Blind Flanges, Duplex Steel Socket Weld Flanges, SS Duplex Threaded Flanges, Duplex Alloy Forged Flanges and DSS Plate Flanges. Buy directly from Duplex Steel Flanges manufacturers in India for Factory price.
Duplex Blind Flanges are used in the following sectors such as water desalinization, chemical, power, petrochemical, marine, oil and gas production and pulp and paper. Duplex Slip On Flanges are designed specifically for use in applications which call for the need of exceptional strength and corrosion resistance, such as petrochemical processes, seawater equipment and chemical processing. These Duplex 2205 Flanges are specifically used in areas where the corrosive conditions are extremely high.
The ASTM A182 specification covers stainless steel alloys which have been produced by either forging or rolling. This Duplex 2205 specification also covers components such as pipe flanges, forged fittings, and valves and parts, which have been meant for high temperature service. After hot working, the forged stainless steel grade 2205 Duplex Flange must be cooled to a specific temperature prior before being heat treated. The alloy must be heat treated keeping in accordance to certain requirements such as heat treatment type, cooling media, austenitizing /solution temperature as well as quenching. The material according to the ASTM A182 needs to conform to the required chemical composition. For instance the Duplex Steel 2205 Weld Neck Flanges must be contain elements such as carbon, silicon, nickel, chromium, molybdenum, manganese, phosphorus, columbium and titanium. The material used to produce this Alloy 2205 Flange must conform to the requirements as to mechanical properties of the specification for the grade ordered. These requirement or mechanical parameters for the specified component such as the Duplex 2205 Forgings includes elongation, tensile strength, yield strength, Brinell hardness. All H grades as well as grade F 63 needs to be tested for average grain size as specified in the standard.
The microstructure of this alloyed Duplex Stainless Steel Flange grade is a two phased one. Thus, the matrix of the DIN 1.4462 Flange has both ferritic & austenitic structures. A duality in their microstructure does not only change the mechanical properties but also its corrosion resistance properties too. The chemical composition of UNS S31803 Socket Weld Flanges consists of 22% chromium, 3% molybdenum as well as 5 to 6% nickel. Because of its high content in this alloyed stainless steel, this grade is also referred to as 22 Cr Duplex Steel . the Duplex Stainless Steel 2205 Flange SORF is the most widely used category of the stainless steel grades.
The 22 Cr Duplex Steel Plate Flange is typically characterized by high yield strength. In fact, the tensile strength of this particular grade tends to be double or two times that of the standard austenitic stainless steel grades. Further, the 2205 Stainless Steel Flanges also displays good fatigue strength, as well as outstanding resistance to chlorine ion related stress corrosion cracking. Other properties of the Duplex 2205 Flanges includes superior resistance to crevice corrosion, pitting, erosion corrosion as well as general corrosion even in severe environments.
Typically, the Duplex 2205 Flat Face Flanges manufacturer recommend using this stainless steel grade is used in industrial applications such as Chemical processing, transport and storage – pressure vessels, tanks, piping, and heat exchangers, Effluent scrubbing systems, Cargo tanks for ships and trucks, Oil and gas exploration and processing equipment – piping, tubing, and heat exchangers. The other applications of the SAF 2205 Flanges include their use in Marine and other high chloride environments, Biofuels plants, Pulp and paper industry – digesters, bleaching equipment, and stock-handling systems as well as Food processing equipment. Key industries that use these Duplex 2205 Flanges include Bitumen upgraders, Nuclear power (mostly seamless), Heavy oil refineries as well as Petrochemicals and acids.
