12820-80 pn16 duplex steel flange

Duplex steel flanges are widely used in the used engineering, machinery and automotive industries. Duplex Steel S31803 Lap Flanges are ideal for applications requiring better corrosion resistance than Type 316 and good high temperature strength. We have Duplex Steel S31803 / S32205 Flanges in stock. Duplex steel flanges are commonly used in chemical, petrochemical, and power industries.

UNS S32205 Duplex Steel ASME SA182 Butt Weld Flanges are suitable for seawater and power generation equipment because their smooth surfaces can withstand temperatures up to 600¡ãF, while also having excellent flow characteristics.

Dual-phase steel butt-welded raised face flanges provide excellent and consistent machinability for increased cutting speeds, reduced tool wear and set-up time.

The high chromium, molybdenum and nitrogen content of 2205 provides better corrosion resistance than common stainless steels such as 316L and 317L in most environments. This exotic alloy is used in oil and gas exploration and is also used in the chemical processing industry .

The flange a182 f53 can also differ in the face type as flat face, raised face and ring type joint flanges.

Duplex steel flanges have some excellent properties such as strong construction, higher yield strength, superior finish, higher toughness, corrosion resistance, and more. It is widely used in various applications and industries. These flanges are highly resistant in corrosive, acidic and reducing environments.

Since duplex stainless steels have lower nickel and molybdenum content than austenitic stainless steels, they tend to have similar corrosion resistance. The lower alloy content of duplex stainless steel means lower costs. This is true, especially when alloy surcharges are high. Also, due to the higher yield strength of duplex stainless steels compared to austenitic stainless steels, it is often possible to reduce their section thicknesses. This combination can significantly reduce the cost and weight of 150 grade duplex pipe flange dimensions compared to components in austenitic stainless grades.

Duplex 2205 flanges are made of dual nature steel with austenitic and ferritic microstructures. The material is resistant to chloride stress corrosion. It is used in corrosive environments. 2205 flanges are available in grades from 150 to 2500 and PN6 to PN64.

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.

Super Duplex Steel Butt Weld Flange for applications requiring excellent strength and corrosion resistance. It offers excellent corrosion resistance due to a balanced chemical composition. In addition, it performs well in environments containing chemicals such as chlorides, halides, sulfides, sulfuric acid, nitric acid, phosphoric acid, etc.

Duplex’s superior mechanical and chemical properties are offset by its formability difficulties. These grades are great for simple flanged connections for fixed services, but are less effective when forming complex metal shapes. Fortunately, machinability of dual-phase steels in complex and circular structures is not an issue in structural steels, given the widespread preference for simple mild steels in non-corrosive 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.

The base body of the DIN 1.4462 flange has both a ferritic and austenitic structure. The duality of their microstructure changes not only the mechanical properties but also their corrosion resistance properties. The chemical composition of UNS S31803 Socket Weld Flanges consists of 22% chromium, 3% molybdenum, and 5% to 6% nickel.

Duplex steel flanges are hardened alloys that are also very corrosion resistant. The microstructure of this steel consists of a mixture of ferrite and austenite phases. Therefore, they have the characteristics of both ferritic and austenitic stainless steels.

This in turn sensitizes the grain boundary, weakening and corroding it. The benefit of welding alloy 2507 blind flanges is that the chemistry in their alloy has a very low carbon content. This makes it difficult to form carbide precipitates and inadvertently prevents intergranular corrosion.

With an increased chromium content compared with F51 it offers improved pitting corrosion resistance.

Use of duplex and super duplex stainless steels should be limited to below 570¡ãF, as prolonged exposure to high temperatures can make the material brittle.

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.

Flanges also have different faces such as raised face, flat face and ring joint. Flange applications are found in aerospace, nuclear engineering and chemical industry applications. Duplex stainless steel butt weld flanges have a weld neck for extra grip before and after welding.

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 steels were introduced to the market as a means to address the problems associated with stress-related corrosion cracking caused by chlorine solutions. The chemical composition of the duplex flange material also makes flanges less prone to chlorine-induced pitting corrosion. These alloys are less expensive than nickel-based steels.

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.

This is designed to be connected to the piping system by butt welding. It is relatively expensive due to its long neck, but is preferred for high stress applications. The neck or hub transfers stress to the bottom of the hub to the wall thickness at the butt weld, providing significant reinforcement for the flange. Flange holes match pipe holes to reduce turbulence and erosion.

Super Duplex Flanges are highly weldable. This alloy can be easily welded by various welding operations. These super duplex flanges are known for their high fatigue strength and provide high strength at moderate temperatures in the lower temperature range.

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.

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.

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.

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.

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