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).

This alloy resists chloride environments and sulfide stress corrosion. It is also roughly double the strength of standard austentic stainless steels.

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.

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

Duplex steel butt welding flange forgings are difficult to form due to their high strength and work hardening rate. However, due to the presence of a large amount of stainless steel, the flange is highly resistant to seawater-related corrosion.

Using UNS S31803 Duplex Steel Pipe Flanges ensures high performance, higher corrosion resistance and longer service life. Due to the dual nature of austenitic and ferritic microstructures present in equal proportions, the dual phase steel RTJ flange material inherits the properties of both steels.

To be able to form a piping system, pumps, pipes, valves and various other equipment are connected together by so-called flanges. These flanges are almost always threaded or welded. Flanges are great because they can be easily inspected, cleaned, or any desired modification.

2205 flange has good general corrosion resistance, high resistance to chloride stress corrosion cracking, as well as pitting and crevice corrosion.

Duplex 2205 flanges are made of dual nature steel with austenitic and ferritic microstructures. The material is resistant to chloride stress corrosion. It is used in corrosive environments. 2205 flanges are available in grades from 150 to 2500 and PN6 to PN64.

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.

Compared to other steels, our duplex stainless steel flanges contain more chromium and therefore have good corrosion resistance. Duplex steel slip types on flanges contain about 10% chromium. Duplex Steel Blind Flanges (BLRF) are thermally stable and have moderate strength even at high temperatures.

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.

As a medium alloy steel, Duplex Blind Raised Face Flanges offer excellent corrosion resistance and twice the mechanical strength in most media compared to standard austenitic stainless steel ASTM 316L.

The combination of chromium, molybdenum and nitrogen provides Duplex 2205 flanges with good chloride pitting and crevice corrosion protection, which makes them useful in marine environments, brackish water, bleach operations, closed loop water systems and some food processing applications. Although it is important to remember that pitting corrosion can be a problem in chloride solutions when oxidizing media are present. Under these conditions, the passive (protective) layer of the Duplex 2205 material may be damaged and localized pitting may occur.

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 .

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 2205, UNS S32205, is a stainless steel material that derives its “duplex” name from a mixed microstructure containing roughly equal portions of ferrite and austenite. This grade is the most popular variety, and this two-phase material is a significant upgrade over 316 stainless steel in terms of yield strength and corrosion resistance.

Chromium, molybdenum, nitrogen and nickel are the most important alloying elements, which have a significant effect on the mechanical, physical and corrosion properties of duplex stainless steels. Chromium is necessary to form a stable chromium passivation film sufficient to protect steel from mild atmospheric corrosion. The higher the chromium content, the better the corrosion resistance.
