Duplex steel flanges are light in weight and perfect in size and other parameters. These are used in the manufacturing industry. In this case, stainless steel is used, so the corrosion resistance of this product is very good. Duplex blind flanges have the characteristics of high strength and are widely used in petrochemical, electric power and other industries. This needs to be used at some specific temperature as it can become brittle at high temperatures.

This increase in alloyants is what gives the super duplex stainless steels greater corrosion resistance properties.

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.

The high temperature strength of dual phase steel slip flanges is similar to alloy grade 430 in the temperature range of 950 to 1150¡ãC. However, the tensile strength of these flanges increases rapidly below 900¡ãC.

Materials according to ASTM A182 need to meet the required chemical composition. For example, dual phase steel 2205 butt weld flanges must contain elements such as carbon, silicon, nickel, chromium, molybdenum, manganese, phosphorus, columbium and titanium. The material used to produce this Alloy 2205 flange must meet the mechanical performance requirements of the grade specification ordered.

Using UNS S31803 Duplex Steel Pipe Flanges ensures high performance, higher corrosion resistance and longer service life. Due to the dual nature of austenitic and ferritic microstructures present in equal proportions, the dual phase steel RTJ flange material inherits the properties of both steels.

Butt weld flanges are flanges designed to be connected to piping systems by butt welding. This type of flange comes in a wide range of sizes, butt weld flanges are expensive due to their long necks and the cost of personnel to contact the WN flange with the pipe or fitting, but are preferred for high stress applications. The neck or hub transfers the stress to the pipe.

ASTM A182 F51 flanges refer to pipe flanges made from the forged duplex stainless steel grade UNS S31803 for use in pressure systems.

In comparison to SS316, Duplex 2205 has been tested under reverse bending stresses at room temperature. The results show that the fatigue limit/yield strength is about twice as high for Duplex 2205.

The 2205 Duplex Butt Weld Flange is a low carbon version that is not affected by sensitization and avoids carbide precipitation in welding applications.

ASTM A182 specification covers stainless steel alloys produced by forging or rolling. This Duplex 2205 specification also covers components for high temperature service such as pipe flanges, forged fittings, valves and parts. After hot working, forged stainless steel grade 2205 duplex flanges must be cooled to a specific temperature before heat treating. Alloys must be heat treated according to certain requirements, such as heat treatment type, cooling medium, austenitizing/solution temperature, and quenching.

The structure of 2205 duplex stainless steel consists of a pool of austenite surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. 2205 is often referred to as the workhorse grade and is the most widely used grade in the duplex stainless steel family.
