We have Duplex Steel S31803 / S32205 Flanges in stock. Duplex steel flanges are commonly used in chemical, petrochemical, and power industries.

There are different pressure ratings for the flanges based on the system of measurement. Under the ANSI standard, the pressure classes range from class 150 through class 2500.

Duplex 2205 is a nitrogen enhanced duplex stainless steel designed to solve common corrosion problems encountered with 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic (such as 304 stainless steel) nor purely ferritic (such as 430 stainless steel).

Duplex 2205 flanges combine the qualities of stress corrosion cracking resistance and high strength derived from being a ferritic alloy along with its austenitic fabrication capabilities.

ASTM A182 F53 flanges refer to flanges made from super duplex stainless steel 2507 (UNS S32750) by a hot forging process.

Both austenite and ferrite are present in the microstructure of this alloy. Therefore, super duplex flanges have similar properties to these two stainless steels. These components have excellent performance in applications exposed to chlorine solutions.

The SA 182-F51 S31803 comes under ASME B16.47, B16.48 and B16.5 standards with sizes ranging from 1/8 NB to 48NB.

Duplex¡¯s premium mechanical and chemical properties are slightly offset by its difficulty in formability.

Super Duplex 2507 Butt Weld Flanges have improved corrosion resistance, making themselves suitable for applications prone to stress corrosion cracking, crevice corrosion, pitting, erosion and general corrosion. Due to the characteristics of duplex and super duplex stainless steel butt weld flanges, they are often used in chemical processing, petrochemical, power industry and seawater equipment.

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.

Compared to other steels, our duplex stainless steel flanges contain more chromium and therefore have good corrosion resistance. Duplex steel slip types on flanges contain about 10% chromium. Duplex Steel Blind Flanges (BLRF) are thermally stable and have moderate strength even at high temperatures.

Duplex stainless steel S31803/S32205/2205 flanges are supplied with good sulfide stress corrosion resistance, high strength and excellent impact toughness. These dual phase steel S31803 slip flanges are chemically balanced to produce a microstructure of approximately 50/50 ferrite to austenite ratio.

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.

Sizes range from ?” to 48″. Pressure ratings range from 150 psi to 2500 psi and more. There are also different types of flanges for different applications. ASME SA182 F51 RTJ flanges have two rings as two halves that are joined at the joint by welding.

Butt weld flanges are the most popular type of high pressure pipeline flange. The tapered hub design of butt weld flanges provides an extremely strong connection, and butt weld flanges can be manipulated and bent repeatedly without compromising material and/or connection quality . Butt weld flanges also have the advantage of being highly resistant to extreme high and low temperatures.

Chromium, molybdenum, nitrogen and nickel are the most important alloying elements, which have a significant effect on the mechanical, physical and corrosion properties of duplex stainless steels. Chromium is necessary to form a stable chromium passivation film sufficient to protect steel from mild atmospheric corrosion. The higher the chromium content, the better the corrosion resistance.

Duplex steel flanges are designed to improve resistance to pitting corrosion, high strength, stress corrosion, crevice corrosion and cracking. Duplex steel sliding flanges resist sulfide stress corrosion and chloride environments. Duplex steel flat flanges are an important part of the duplex steel flange family.

Offshore marine engineering plants need compenents that meet their rugged demands, components that have mammoth strenght but are light weight.

Duplex flanges are made of a special stainless steel with austenitic and ferritic metallurgical features in its microstructure. These are magnetic steels with high corrosion resistance and work hardening.

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.

Long weld flanges help with high pressures and the need for a long, tapered hub is the most common use for weld neck flanges. When ordering, it is most important to specify the pipeline plan that will be used. This flange is ideal for use in environments involving extreme temperature fluctuations and excessive handling and bending.

Duplex steel Werkstoff No 1.4462 threaded flanges also cannot be used below -50¡ãC as it will cause a ductile to brittle transition. Duplex UNS S32205 Orifice Flange has a tensile strength of 1,16,000 psi 800 MPa. Whereas the duplex SAF 2205 socket weld flange has a yield strength of 80,000 psi 550 MPa. 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 UNS S31803 Duplex Flanges are mainly suitable for the four groups Martensite, Ferritic and Austenitic, and finally hardened steel. These are forming because they are based on crystal structures and stainless steel. They give you the facility to withstand high temperatures and also give them the strength of UNS S322O5 butt welded pipe. They are said to be made from a chemical composition of equal proportions of austenite and ferrite.

These high-strength flanges securely seal a range of plumbing modules. The multifunctional flange shows good stability and exhibits enhanced resistance to chloride pitting in marine applications. With standard welding procedures, Super Duplex Flanges can be easily welded to different piping modules.

Duplex stainless steel grades are named duplex because these duplex flange equivalent grades have a two-phase microstructure. This two-phase microstructure consists of ferritic and austenitic stainless steel-like grains. As the name suggests, the duplex construction gives this duplex stainless steel socket weld flange material a variety of attractive properties.

Duplex stainless steel flanges, these flanges have some excellent properties such as light weight, robust construction, accurate dimensions and more. We also offer these products in different grades such as Duplex Flanges, Duplex Flanges, Super Duplex Flanges and Super Duplex Flanges.
