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.

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.

The different face types have their own advantages in piping 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.

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.

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.

At this temperature, duplex steel flanges over 300 degrees Celsius are still protected from embrittlement due to corrosion. Duct capability is also excellent at low temperatures. Fabrication is done only with tools assigned to stainless steel materials. Must be properly cleaned before use. This is done to protect the stainless steel from cross-contamination of the corroding metal.

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.

For standard austenitic stainless grades (such as 304 and 316), SCC can be a problem in environments with humidity and high temperatures or with certain chemicals such as chlorides. Therefore, duplex blind flange suppliers often supply them to industries such as oil and industrial, gas, petrochemical and marine industries.

Compared to similar ferritic and austenitic grades, the super duplex steel 1.4410 flange has a lower alloying cost and, due to the well improved yield and tensile strength, has Corrosion resistance.

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.

The ASTM A182 F53 UNS S32750 Flange comes under the ASTM A182 specification for high temperature and high pressure services.

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.

We are one of the largest producers of duplex steel sliding flanges with good fatigue strength and high corrosion resistance. 2205 Duplex Steel Blind Flange is also known for its various mechanical properties, such as excellent resistance to cracking, pitting, and corrosion in harsh environments.

The granular structure of the duplex is a ferrite-austenite hybrid material with a higher strength-to-weight ratio than 304 or 316. It balances the weldability of austenite with pure ferrite and maintains good mechanical toughness in applications exposed to cooler ambient temperatures. Offshore/seawater applications are common uses of this type of steel due to its excellent stress corrosion cracking properties. Therefore, duplexes are often found in desalination and pressure vessel plants located in port cities.

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.

We offer a complete range of flanges, including slip flanges, socket weld flanges, blind flanges, lap flanges, threaded flanges, butt weld flanges, reducer flanges, and more. Due to a wide range of customer requirements, we offer these super duplex steel UNS S32750 flanges in a variety of sizes.

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.

Butt weld flanges are flanges designed to be connected to piping systems by butt welding. There are many specifications of this flange. Butt weld flanges are expensive because of their longer necks and high personnel costs for WN flanges in contact with pipes or fittings, but are preferred for high stress applications. The neck or hub transfers the stress to the pipe.

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.

These grades are excellent for fixed service simple flange connections, but slightly less so when forming a complex metallic shape. Fortunately, the workability of duplex into complex and rounded structures is less of an issue in structural steel given the wide preference for simple mild steel in non corrosive applications.

There are SA 182 F53 S32750 Blind Flanges, socket weld flanges and weld neck flanges in this range of material. The different flanges are used in different applications set ups.

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.

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.

Super Duplex 2507 Butt Weld Flanges have improved corrosion resistance, making themselves suitable for applications prone to stress corrosion cracking, crevice corrosion, pitting, erosion and general corrosion. Due to the characteristics of duplex and super duplex stainless steel butt weld flanges, they are often used in chemical processing, petrochemical, power industry and seawater equipment.

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 high chromium, molybdenum and nitrogen content of 2205 provides better corrosion resistance than common stainless steels such as 316L and 317L in most environments. This exotic alloy is used in oil and gas exploration and is also used in the chemical processing industry .

Both austenite and ferrite are present in the microstructure of this alloy. Therefore, super duplex flanges have similar properties to these two stainless steels. These components have excellent performance in applications exposed to chlorine solutions.

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

2205 helps users to avoid stress corrosion cracking that is typically seen with 316 and 317.
