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).

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.

Chromium is a ferrite former, which means it promotes the BCC structure of iron. It also increases oxidation resistance at high temperatures. Higher chromium also promotes the formation of intermetallic phases, which are detrimental to duplex stainless steels and should be addressed.

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.

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.

Duplex 2205 was tested under reverse bending stress at room temperature compared to SS316. The results show that Duplex 2205 has approximately twice the fatigue limit/yield strength.

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.

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

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.

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.

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.

Duplex stainless steel flanges, these flanges have some excellent properties such as light weight, robust construction, accurate dimensions and more. We also offer these products in different grades such as Duplex Flanges, Duplex Flanges, Super Duplex Flanges and Super Duplex Flanges.

For many applications where 300 series stainless steel is susceptible to chloride stress corrosion cracking, 2205 duplex stainless steel is a cost-effective solution. Stress corrosion cracking occurs when stainless steel is subjected to tensile stress while in contact with solutions containing chlorides. Elevated temperatures also increase the susceptibility of stainless steel to stress corrosion cracking.

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.

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.
