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.

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.

ASTM A182 UNS S31803 Duplex Flanges are mainly suitable for the four groups Martensite, Ferritic and Austenitic, and finally hardened steel. These are forming because they are based on crystal structures and stainless steel. They give you the facility to withstand high temperatures and also give them the strength of UNS S322O5 butt welded pipe. They are said to be made from a chemical composition of equal proportions of austenite and ferrite.

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.

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.

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.

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

A secondary task of duplex steel flanges is to facilitate workers who access these systems to clean, inspect or modify them. In general, applications of duplex stainless steel flanges are found in the following industries, namely chemical plants, chemical tankers, thermal power plants, desalination plants, seawater pumps, flue gas desulfurization plants, construction works, and pulp and paper mills. These industries utilize piping systems to transfer media, which often creates some kind of pressure on conventional flanges.

Due to the material composition, the strength and the corrosion resistance, these flanges are used in a variety of applications.
