Duplex steel flanges are made of duplex steel material and belong to the stainless steel family. It is designed to provide better corrosion resistance, especially chloride stress corrosion and pitting corrosion, and higher strength than standard austenitic stainless steels such as stainless steel 304 or stainless steel 316.

Duplex is often found in desalination and pressure vessel equipment located in port cities.

Super Duplex Flanges are designed with high alloy duplex steel. These flanges have a two-phase structure with austenitic and ferritic microstructures. Designed with high concentrations of nickel, chromium and molybdenum, these modules exhibit excellent corrosion and oxidation resistance in stress-inducing systems.

Corrosion Duplex 2205 flanges provide the industry with an improved stainless steel corrosion solution with good sulfide corrosion resistance and better resistance to chloride pitting and crevice corrosion than 317L.

For many applications where 300 series stainless steel is susceptible to chloride stress corrosion cracking, 2205 duplex stainless steel is a cost-effective solution. Stress corrosion cracking occurs when stainless steel is subjected to tensile stress while in contact with solutions containing chlorides. Elevated temperatures also increase the susceptibility of stainless steel to stress corrosion cracking.

The pressure ratings of the material are designated by classes 150Lbs through 2500LBs. There are different types of the duplex f51 flanges such as the raised face, ring type joint and flat face flanges.

It has the nominal composition of 22Cr-5Ni-3Mo-N with P number 10H.

Duplex steel butt welding flange forgings are difficult to form due to their high strength and work hardening rate. However, due to the presence of a large amount of stainless steel, the flange is highly resistant to seawater-related corrosion.

Compared to the corresponding austenitic steels, they are more prone to precipitation of sigma phases, nitrides and carbides, leading to embrittlement and reduced corrosion resistance. Duplex steel pipe flanges are an ultra-steel suitable for use in highly corrosive conditions where very high mechanical strength is required.

Other applications for 2205 flanges include use in marine and other high chloride environments, biofuel plants, pulp and paper industry – digesters, bleaching equipment, stock handling systems, and food processing equipment. Major industries using these Duplex 2205 flanges include asphalt upgrading plants, nuclear power (mostly seamless), heavy oil refineries, and petrochemicals and acids.

The yield strength of duplex stainless steel is twice that of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more cost-effective than 316, 317L.

Super Duplex Steel Butt Weld Flanges are inherently non-magnetic. Austenitic stainless steel also contains nickel, molybdenum, copper, niobium, aluminum, etc. in chemical composition. It shows similar austenite and ferrite grades.

An austenitic-ferritic stainless variant with a higher stress corrosion cracking resistance in comparison to regular austenitic 304 and 316 stainless, but with a lower toughness and impact strength.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

Duplex Steel UNS Grade S32205 Duplex Steel is resistant to chloride environments and sulfide stress corrosion. Its yield strength is approximately twice that of standard austenitic stainless grades. Duplex steel UNS S32205 flanges are extremely durable and can also be easily installed to any size thanks to the different shapes and sizes available.

ASTM A182 F51 equates to UNS S31803. This was the original caption for a 22% Cr duplex stainless steel.

2205 flange has good sulfide stress corrosion resistance and high strength and good fatigue resistance.

The flanges shall not be used at temperatures over 600¡ãF [315¡ãC] since it may be subject to embrittlement after service at moderately elevated temperatures.
