6 inch class 300 duplex steel 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.

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

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.

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.

A182 F51 Duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance.

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.

The material has high strength and corrosion resistance. The A182 F53 material is used to make flanges ranging from 1/2 inches to 48 inches under different standards such as ANSI, ASME, DIN and other international standards.

This is the main reason why Super Duplex Flanges note an improvement of tensile strength over ferritic and austenitic steel grades.

Astm A182 F51 flange is made up of carbon, chromium, manganese, silicon, phosphorus, sulfur, nickel, nitrogen, molybdenum and iron.

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.

Pipe flanges are widely used as a popular category of pipe fittings. Flanges are used to mechanically connect two pipes together. It can also be used to mechanically connect pipes to tees, valves, chokes or any other device. Flanges are available in round, square and rectangular. In some cases, flanges are usually ring-shaped or plate-shaped to form a rim at the end of the pipe when fastened to the pipe.

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.

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 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.

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

The ASTM A182 UNS S32750 Slip On Flanges are good to use with seamless pipes.

Super Duplex Steel 1.4410 Flanges are having low alloying costs as compared to the similar ferritic and austenitic grade along with resistant to corrosion in the chloride-containing atmosphere because of well-enhanced yielding and tensile strength.

Duplex S31803 butt weld flanges combine good mechanical strength and ductility with moderate to good corrosion resistance in a variety of environments. Duplex S31803 threaded flanges are the most widely used duplex stainless steel grade. Duplex S31803 lap joint flanges feature a high yield strength that is twice that of standard austenitic stainless steel grades.

Super Duplex UNS S32760 Reducing Flanges have a strengthened microstructure, a result of added Nitrogen, allowing fabrication of thin and low-weight flanges that are easy on the pocket.

Based on composition, materials can be classified as Standard Duplex, Super Duplex, and Lean Duplex. Duplex steel flanges are suitable for high pressure, high temperature and highly corrosive applications. Duplex is also cost effective and has recently been used and replaced by other material grades.

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.

ANSI B16.5 Duplex Stainless Steel Plate Flanges are available in pressure ratings from 150 to 2500, and the standard covers pipe nominal sizes from NPS ? to NPS 24. The duplex stainless steel flange material we manufacture meets international standards. We produce different grades of duplex steels that require different qualities to be used in different applications.

The high temperature strength of dual phase steel slip flanges is similar to alloy grade 430 in the temperature range of 950 to 1150¡ãC. However, the tensile strength of these flanges increases rapidly below 900¡ãC.

To be able to form a piping system, pumps, pipes, valves and various other equipment are connected together by so-called flanges. These flanges are almost always threaded or welded. Flanges are great because they can be easily inspected, cleaned, or any desired modification.

Duplex and Super Duplex Welding Flanges are ideal for critical applications involving high pressure, sub-zero and high temperature, as well as conditions where fluctuations cause expansion/contraction of the pipeline, and its main feature is that it is suitable for high pressure applications.

Duplex flanges are dual microstructures consisting of austenitic and ferritic grades. Versatile grades are designed with excellent chemical concentrations of chromium, nickel and small amounts of molybdenum. The excellent concentration makes these modules more resistant to aggressive and oxidizing media.

These flanges have excellent resistance in acidic solutions such as nitric acid, sulfuric acid, phosphoric acid, etc. Additionally, our duplex steel flanges perform well in seawater and chloride solutions. Our experts are producing dual phase steel F60 flanges with excellent properties such as strong properties, higher tensile strength, durability, machinability, ease of manufacture, excellent surface finish and longer service life.
