2 inch duplex steel slip-on flanges

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 stainless for e.g. alloy UNS S32750, has a mixed microstructure of both austenite as well as ferrite in an equal or 50/50 ratio.

The flanges are internally drilled to match the inside diameter of the pipe to ensure unrestricted flow and prevent turbulence at the joint. The tapered neck provides thicker metal at the flange joint, while the neck tapers to butt against the pipe and to butt against the pipe. This design helps transfer stress from the flange to the pipe and reduces stress concentrations at the bottom of the flange connection.

Due to its high content in this alloyed stainless steel, this grade is also known as 22 Cr duplex steel. Duplex Stainless Steel 2205 Flange SORF is the most widely used category of stainless steel grades. A typical feature of 22 Cr duplex steel plate flanges is high yield strength. In fact, the tensile strength of this special grade is often double or twice that of standard austenitic stainless grades.

Duplex steels have both ferritic and austenitic microstructures. Due to the excellent mechanical strength and electrical resistance properties, our flanges are widely used in different industrial applications such as petrochemical, chemical equipment, oil and gas processing, automotive, etc.

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.

ASTM A182 F53 Flange is a high strength flange that has 550MPa minimum yield strength and 800MPa minimum tensile strength.

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.

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

2205 flange has good general corrosion resistance, high resistance to chloride stress corrosion cracking, as well as pitting and crevice corrosion.

It has the nominal composition of 22Cr-5Ni-3Mo-N with P number 10H.

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

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 flanges shall not be used at temperatures over 600¡ãF [315¡ãC] since it may be subject to embrittlement after service at moderately elevated temperatures.

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.

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

These super duplex steel UNS S32760 flanges are technologically advanced using premium materials under the guidance of skilled experts. They have outstanding features such as resistance to plastic deformation, wear resistance, chipping resistance, and good machinability.

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.

An austenitic-ferritic stainless variant with a higher stress corrosion cracking resistance in comparison to regular austenitic 304 and 316 stainless, but with a lower toughness and impact strength.

Super Duplex Flanges use pure quality alloys with mixed austenitic and ferritic microstructures and high molybdenum and chromium content. This superior chemical composition provides superior resistance and increased strength. The products we manufacture are used in a wide variety of applications and industries. These flanges are highly resistant in corrosive, acidic and reducing environments.

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 flanges could also be manufactured as screwed, threaded or forged types. The forged flanges are made from a single piece of raw material. These are also called the cast flanges.

Some 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. 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.

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 basic idea of dual-phase steel long butt weld flanges is to produce a chemical composition that makes a roughly equal mixture of ferrite and austenite. The chemical composition of duplex steel lap flanges is balanced to produce approximately equal amounts of ferrite and austenite under solution annealed conditions.

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).

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 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.

The combination of chromium, molybdenum and nitrogen gives 2205 good resistance to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. 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, and Citizen Metals has been actively involved in ensuring the best possible quality for our customers.

A secondary task of duplex steel flanges is to facilitate workers who access these systems to clean, inspect or modify them. In general, applications of duplex stainless steel flanges are found in the following industries, namely chemical plants, chemical tankers, thermal power plants, desalination plants, seawater pumps, flue gas desulfurization plants, construction works, and pulp and paper mills. These industries utilize piping systems to transfer media, which often creates some kind of pressure on conventional flanges.

Duplex 2205 Butt Weld Flanges (WN Flanges) are easily identifiable at the long tapered hub, gradually extending from the pipe or fitting to the wall thickness. Long tapered hubs provide significant reinforcement for use in a variety of applications involving high pressure, sub-zero and/or high temperature. A smooth transition from flange thickness to pipe or fitting wall thickness is very beneficial in the case of repeated bending caused by linear expansion or other variable forces.
