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.

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.

Super Duplex 2507, UNS S32750, is a duplex stainless steel especially suitable for environments such as warm chlorinated seawater and acidic chlorinated media. It has similar properties to Duplex 2205 but is more corrosion resistant and performs well in moderately corrosive environments.

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.

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.

Duplex stainless is a mixed microstructure of austenitic and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.

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.

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.

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.

Butt welding flanges are drilled (machined), and the wall thickness of the flange is the same size as the matching pipe. The lighter the tube, the larger the diameter, and conversely, the heavier the tube, the smaller the diameter. Our range of butt weld flanges, butt weld flanges are typically used for high pressure, low temperature or high temperature.

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.

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.

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 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 S31803 Flanges are used in marine engineering, chemical processing, hydrocarbon processing, heat exchangers, valve manufacturing, pump manufacturing, petrochemical plants, nuclear power projects, oil and gas equipment manufacturing.

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.

Each different type has its own advantages. Different grades of duplex steel have different mechanical and physical properties due to different chemical compositions. ASTM A182 F60 flanges are high performance, cost effective and long life flanges. There are different face types such as ring joint flanges, flat face flanges and raised face flanges.

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 term “flange” is also used for a kind of tool used to form flanges.

The chemical composition of Duplex F51 flanges contains carbon, chromium, manganese, molybdenum, nitrogen, nickel and phosphorus. Flanges are used in pressure systems and valve fittings.

The applications include high corrosive applications including acidic applications due to the material composition.

Super Duplex Steel Flanges are ideal for service in severely corrosive environments such as offshore and marine applications. It is also particularly resistant to chloride SCC. Flanges provide equivalent pitting resistance, ensuring very good pitting resistance. All of our product ranges are strength tested, including pitting corrosion testing, toughness testing, chemical and mechanical testing, macro and micro testing, and more.

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.

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.

These dual phase steel S32205 ring joint flanges also feature high corrosion and erosion fatigue performance as well as lower thermal expansion and higher thermal conductivity than certified.
