1-2 S31803 S32205 DUPLEX female npt threaded raised flange

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.

ASTM A182 F51 equates to UNS S31803. This was the original caption for a 22% Cr duplex stainless steel.

UNS S32205 ASTM A182 flanges have good resistance to chloride pitting and crevice corrosion due to a combination of chromium, molybdenum and nitrogen. The exotic duplex 2205 flange alloy is used in oil and gas exploration, this alloy is also used in the chemical processing sector.

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.

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.

The material has high strength values. The minimum yield strength is 450MPa and the minimum tensile strength is 620MPa, with 25% minimum elongation and 290HB Brinell hardness.

Duplex steel flange also offers Good weldability and workability, High energy absorption and Low thermal expansion.

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.

They have a design that allows for the pipes to pass through the flange and locate the correct point for connection. The ASTM A182 grade F53 WNRF Flange has a welded neck raised face.

Super Duplex UNS S32750 /F53 Flanges are made from a super duplex stainless steel grade that has 24% chromium, 3% molybdenum, 6% nickel and carbon, manganese, silicon, sulfur, phosphorus, nitrogen and iron in the composition.

Duplex flanges consist of a material type called duplex. The material has both ferritic and austenitic microstructures in metallurgy. There are different grades of duplex depending on the material composition. Duplex stainless steel flanges have the best ferritic and austenitic properties. They are used as replacements for expensive high alloys in many industrial applications.

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

The raised face allows for the flange to have more bolt holes and connection surface while the welded neck grips the pipe in place. The applications are oil and gas, petroleum, petrochemical and other industrial applications.

Double butt weld flanges are best suited for hazardous high pressure applications. Butt weld flanges are easily identified by their long tapered neck.

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.

The mechanical strength, corrosion resistance and low temperature toughness of the ASTM A182 F53 Flanges is higher than that of ordinary duplex stainless steels.

This grade, with a tighter specification, is captioned as F60, equating to UNS S32205. Consequently, S32205 can be dual-certified as S31803 but not vice-versa.

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

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.

They are resistant to general corrosion. We are suppliers of ASME SA182 Duplex Steel UNS S32205 Weld Neck Flanges to sea water and power generation equipment.

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.

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.

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.

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.

Most processing equipment uses Duplex 2205. Also used by industrial storage and transportation units. Pulp and paper digesters, liquid tanks and paper machines also use Duplex 2205. It is ideal for use in marine environments.

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.

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.
