Duplex 2205 flanges are made from an austenitic-ferritic stainless steel, which was designed to deliver higher strength and corrosion resistance than 300 series stainless steels.

The base body of the DIN 1.4462 flange has both a ferritic and austenitic structure. The duality of their microstructure changes not only the mechanical properties but also their corrosion resistance properties. The chemical composition of UNS S31803 Socket Weld Flanges consists of 22% chromium, 3% molybdenum, and 5% to 6% nickel.

Flanges also have different faces such as raised face, flat face and ring joint. Flange applications are found in aerospace, nuclear engineering and chemical industry applications. Duplex stainless steel butt weld flanges have a weld neck for extra grip before and after welding.

Duplex’s superior mechanical and chemical properties are offset by its formability difficulties. These grades are great for simple flanged connections for fixed services, but are less effective when forming complex metal shapes. Fortunately, machinability of dual-phase steels in complex and circular structures is not an issue in structural steels, given the widespread preference for simple mild steels in non-corrosive applications.

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.

Since duplex stainless steels have lower nickel and molybdenum content than austenitic stainless steels, they tend to have similar corrosion resistance. The lower alloy content of duplex stainless steel means lower costs. This is true, especially when alloy surcharges are high. Also, due to the higher yield strength of duplex stainless steels compared to austenitic stainless steels, it is often possible to reduce their section thicknesses. This combination can significantly reduce the cost and weight of 150 grade duplex pipe flange dimensions compared to components in austenitic stainless grades.

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 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.

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 in turn sensitizes the grain boundary, weakening and corroding it. The benefit of welding alloy 2507 blind flanges is that the chemistry in their alloy has a very low carbon content. This makes it difficult to form carbide precipitates and inadvertently prevents intergranular corrosion.

The 21% chromium content is the key to extreme corrosion resistance and strength of the SA 182 f51 flanges. HT PIPE is a leading supplier and manufacturer of the flanges in various scales, shapes and types.

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.

Duplex and Super Duplex Welding Flanges are ideal for critical applications involving high pressure, sub-zero and high temperature, as well as conditions where fluctuations cause expansion/contraction of the pipeline, and its main feature is that it is suitable for high pressure applications.

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.

UNS S32750 Flanges are used in seawater piping, desalination plants, mechanical components, high-pressure RO plants, etc. SD pipe flanges are used in heat exchangers, service and process water systems, offshore platform, oil & gas industry, etc. These flanges are also found in line pipes, power industry FGD system, industrial & utility scrubber, absorber tower, pressure vessel, etc.

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

It is listed in Material Group 2.8 according to ASME B16.5 and ASME B16.47.

It is needed when the neck needs to be lengthened. Duplex steel flanges act as extensions. Duplex steel flanges are used in the chemical and petroleum industries for residential and commercial buildings. Duplex steel flanges perform well under pressure levels and temperature fluctuations. Long butt weld flanges are available in various lengths, sizes and dimensions according to customer needs.

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.

Compared to the corresponding austenitic steels, they are more prone to precipitation of sigma phases, nitrides and carbides, leading to embrittlement and reduced corrosion resistance. Duplex steel pipe flanges are an ultra-steel suitable for use in highly corrosive conditions where very high mechanical strength is required.

ASTM A182 Duplex S31803 Slip Flange for high pressure vessels and high pressure applications. The operating temperature range is up to 150 degrees Celsius in chloride-rich environments. This material grade is available with welded flanges, bolted flanges and threaded flanges.

For duplex stainless steel flanges, solution annealing at an appropriate temperature followed by immediate water quenching can achieve the best metallurgical austenite-ferrite phase balance. It is important to keep the time between leaving the furnace and water quenching as short as possible. This is to minimize heat loss from the flange, which can lead to precipitation of detrimental phases before water quenching to room temperature.

Super Duplex Steel Butt Weld Flange for applications requiring excellent strength and corrosion resistance. It offers excellent corrosion resistance due to a balanced chemical composition. In addition, it performs well in environments containing chemicals such as chlorides, halides, sulfides, sulfuric acid, nitric acid, phosphoric acid, etc.

The different face types have their own advantages in piping applications.

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.

All 2205 alloys are metallographically inspected to ensure that products shipped are free of harmful phases such as sigma. It is usually used in the form of welded pipes or tubular parts. The alloy is also used as formed and welded sheet products in environments that are resistant to general corrosion and chloride stress corrosion cracking.

It also greatly increases the strength as the most effective solid solution strengthening element. Nitrogen is a strong austenite former, and the addition of nitrogen greatly improves the toughness of dual-phase steels. It also delays the formation of intermetallic compounds enough to allow processing and fabrication of dual-phase steels. Nickel is an austenitic stabilizer that promotes the formation of the austenitic FCC structure, which contributes to the toughness of dual-phase steels.
