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.

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 2205 flanges are made from an austenitic-ferritic stainless steel, which was designed to deliver higher strength and corrosion resistance than 300 series stainless steels.

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.

It also greatly increases the strength as the most effective solid solution strengthening element. Nitrogen is a strong austenite former, and the addition of nitrogen greatly improves the toughness of dual-phase steels. It also delays the formation of intermetallic compounds enough to allow processing and fabrication of dual-phase steels. Nickel is an austenitic stabilizer that promotes the formation of the austenitic FCC structure, which contributes to the toughness of dual-phase steels.

It is also exceptionally resistance to chloride SCC. Flanges are supplied with pitting resistance equivalent that is assuring very good pitting corrosion resistance.

2205 flanges are highly resistant to pitting and crevice corrosion, perform well in most corrosive environments, and have good weldability. Specifications These dual phase steel S31803 butt weld flanges have good oxidation resistance at high temperatures, but tend to become brittle at temperatures above 300 degrees Celsius and only 2 hours exposure to 475 degrees Celsius.

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.

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). 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.

Duplex 2205 and Super Duplex 2507 stainless steel butt weld flanges feature a high yield strength that is twice the annealed yield strength of typical austenitic stainless steels such as 304 and 316 stainless steel butt weld flanges. Because of this, Duplex 2205 and Super Duplex 2507 steels are some of the most common duplex grades used for butt weld flanges, with Super Duplex 2507 butt weld flange being the more corrosion resistant grade of the two.

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 primary difference between standard duplex grades and the Super Duplex Steel Flanges Material is that Super duplex has a higher content of both molybdenum and chromium their alloy.

All 2205 alloys are metallographically inspected to ensure that products shipped are free of harmful phases such as sigma. It is usually used in the form of welded pipes or tubular parts. The alloy is also used as formed and welded sheet products in environments that are resistant to general corrosion and chloride stress corrosion cracking.

The advantage of the dual-phase structure is that it combines the advantages of ferritic alloys (resistance to stress corrosion cracking and high strength) with the advantages of austenitic alloys (ease of manufacture and corrosion resistance). The service temperature of 2205 duplex stainless steel should be limited to below 600¡ãF. Prolonged exposure to high temperatures can make 2205 stainless steel brittle.

ASTM A182 UNS S32750 Flanges is the most common super duplex grade that has an enhanced pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types.

The chromium content is between 20-28%, which is why UNS S31803/ S32205 blind flanges undergo a phenomenon called passivation. In this phenomenon, a self-healing protective passivating oxide layer surrounds the flange making it resistant to oxidation.

Robust modules resist acid pitting in marine systems. Duplex flanges effectively connect different piping modules in the system and affect the flow of fluids or gases. This grade has higher strength and crack resistance than common austenitic grades. These flanges also have excellent ductility and can be welded in place using standard procedures.

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.

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.

ASME B16.5 Duplex Steel Forged Flanges are available in sizes from 1/8″ to 24″. Depending on the size, flanges are available in different pressure classes. Class 150 Duplex Pipe Flanges are the lowest pressure class up to 2500.

The yield strength is also higher, allowing component designers to reduce section size for load-bearing applications.

Duplex 2205 is characterized by high resistance to chloride stress corrosion cracking, chloride pitting and crevice corrosion resistance, good general corrosion resistance, good sulfide stress corrosion resistance, high strength and good weldability and workability.
