duplex steel S31803 S32205 wn flange pn16

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.

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, 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.

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 formation of intermetallic phases such as sigma phase in duplex steel flange flanges occurs in the temperature range of 600¡ãC – 1000¡ãC, and the decomposition of ferrite occurs in the temperature range of 350¡ãC – 500¡ãC ( 475¡ãC embrittlement).

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.

2205 flanges are highly resistant to pitting and crevice corrosion, perform well in most corrosive environments, and have good weldability. Specifications These 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.

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.

This exotic alloy is used in oil and gas exploration and is also used in the chemical processing industry. 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.

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.

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.

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.

Super Duplex Flanges are highly weldable. This alloy can be easily welded by various welding operations. These super duplex flanges are known for their high fatigue strength and provide high strength at moderate temperatures in the lower temperature range.

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.

Duplex steel flanges are often used for heavy duty welded components. We produce these flanges using high quality raw materials. Our customers trust us in the quality of our products as we continuously strive to improve our technology and provide impeccable products and services.

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.

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

The yield strength is also higher, allowing component designers to reduce section size for load-bearing applications.

2205 is the most widely used duplex stainless steel, accounting for more than 80% of the duplex stainless steel market. Alloy 2205 offers better corrosion resistance in a variety of environments where 316L is typically used, with the added benefit of higher yield strength.

S32205 is a dual-phase steel with nearly equal proportions of austenite and ferrite in its chemical composition. This combination makes the alloy stronger than standard austenitic steels. The Duplex Steel S31803 Ring Fitting Flange is a low carbon version and is immune to sensitization.

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.

This provides the flanges with high corrosion resistance and higher mechanical properties. Please contact us for your orders of F53 flanges.
