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.

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.

It has high strength and excellent corrosion resistance. Duplex stainless steel flanges have excellent intergranular corrosion. It has excellent resistance to corrosion cracking stress even in sulfide and chloride environments.

This alloy is especially useful in the -50¡ãF/+600¡ãF temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some restrictions, especially when used in welded structures.

It reaches the phase balance of austenite and ferrite in roughly same volume fraction.

Weld-neck flanges get their name from the flange necks that are welded to the end of a piping system. It is designed to transfer stress to the pipe, thereby reducing high stress concentrations at the bottom of the flange. Butt weld flanges cost more because of their design and engineering and the added material.

The oxidation resistance of these dual phase steel S31803 butt weld flanges is good at high temperatures, but tends to become brittle at temperatures above 300 degrees Celsius, brittle after only 2 hours of exposure at 475 degrees Celsius.

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.

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.

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.

Molybdenum increases resistance to pitting and crevice corrosion. However, its content in duplex stainless steels is generally limited to less than 4% because Mo is also a ferrite former and can lead to unwanted intermetallic phases. Nitrogen improves resistance to pitting and crevice corrosion.

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.
