105 duplex steel flange for reducer customized

UNS S32205 Duplex Steel ASME SA182 Butt Weld Flanges are suitable for seawater and power generation equipment because their smooth surfaces can withstand temperatures up to 600¡ãF, while also having excellent flow characteristics.

Duplex steel flanges are widely used in the used engineering, machinery and automotive industries. Duplex Steel S31803 Lap Flanges are ideal for applications requiring better corrosion resistance than Type 316 and good high temperature strength. We have Duplex Steel S31803 / S32205 Flanges in stock. Duplex steel flanges are commonly used in chemical, petrochemical, and power industries.

The raised face allows for the flange to have more bolt holes and connection surface while the welded neck grips the pipe in place. The applications are oil and gas, petroleum, petrochemical and other industrial applications.

For 2500# in sizes from NPS 1/2 to NPS 12 ASTM A182 UNS S32750 Flanges, with requirements in both metric and U.S. A182 S32750 Flat Flanges for companies involved in Equipment Manufacturing, Oil Refineries, Mining, Chemical manufacturing and Industrial Construction.

Super Duplex Steel Flanges are ideal for service in severely corrosive environments such as offshore and marine applications. It is also particularly resistant to chloride SCC. Flanges provide equivalent pitting resistance, ensuring very good pitting resistance. All of our product ranges are strength tested, including pitting corrosion testing, toughness testing, chemical and mechanical testing, macro and micro testing, and more.

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.

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 steels were introduced to the market as a means to address the problems associated with stress-related corrosion cracking caused by chlorine solutions. The chemical composition of the duplex flange material also makes flanges less prone to chlorine-induced pitting corrosion. These alloys are less expensive than nickel-based steels.

The applications of the flanges include petroleum, petrochemical, oil and gas and other high performing piping systems.

ASME B16.5 Duplex Steel Forged Flanges are available in sizes from 1/8″ to 24″. Depending on the size, flanges are available in different pressure classes. Class 150 Duplex Pipe Flanges are the lowest pressure class up to 2500.

Duplex steels have high resistance to various types of corrosion. Duplex Steel S31803 is an extremely corrosion-resistant, work-hardenable alloy. Duplex steel S31803 butt weld flanges have good high temperature properties.

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.

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 .

The yield strength is also higher, allowing component designers to reduce section size for load-bearing applications.

As with all stainless steel grades, the corrosion resistance of a metal or alloy depends primarily on the composition of the metal, in this case stainless steel. For resistance to chloride pitting and crevice corrosion, the content of elements such as chromium, molybdenum and nitrogen is considered to be the most important.

Super Duplex UNS S32750 /F53 Flanges are made from a super duplex stainless steel grade that has 24% chromium, 3% molybdenum, 6% nickel and carbon, manganese, silicon, sulfur, phosphorus, nitrogen and iron in the composition.

Both ASME B16.5 and ASME B16.47 have endorsed pipe flanges made from a series of duplex stainless steel grades.

S31803 has been supplemented by S32205 (F60) which dual conforms to S31803 but has a higher minimum N, MO, NI and Cr which guarantees a better corrosion resistance.

Though it is important to keep in mind that pitting corrosion can be a concern in chloride solutions when oxidizing media is present. In these conditions, the passive (protective) layer of the Duplex 2205 material may be compromised in localized pitting may occur.

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.

The ASTM A182 F53 UNS S32750 Flange comes under the ASTM A182 specification for high temperature and high pressure services.

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 flanges have a ductile to brittle transition at -50¡ãC and also become brittle at 300-1000¡ãC, so the recommended service temperature is -50¡ãC to 300¡ãC. Exposure to above 300¡ãC will not only cause embrittlement of the 2205 flange, but will also reduce corrosion resistance.

A182 F51 Duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance.

Duplex stainless steel flanges are widely used in pipeline systems, risers, manifolds, etc. in the offshore gas and oil industries, and also in the petrochemical industry in the form of pressure vessels and pipelines. Duplex 2205 flange material has good strength and high resistance to corrosion, pitting and crevice corrosion. The nominal chemical composition of Duplex 2205 is 22% chromium, 3.2% molybdenum, 5% nickel and other alloying elements such as manganese and nitrogen.

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.

Duplex Steel UNS S31803 Flanges are used in marine engineering, chemical processing, hydrocarbon processing, heat exchangers, valve manufacturing, pump manufacturing, petrochemical plants, nuclear power projects, oil and gas equipment manufacturing.

It accounts for around 80% of overall duplex stainless steel production.

Compared to similar ferritic and austenitic grades, the super duplex steel 1.4410 flange has a lower alloying cost and, due to the well improved yield and tensile strength, has Corrosion resistance.

Duplex steel flanges have some excellent properties such as strong construction, higher yield strength, superior finish, higher toughness, corrosion resistance, and more. It is widely used in various applications and industries. These flanges are highly resistant in corrosive, acidic and reducing environments.

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.

Use of duplex and super duplex stainless steels should be limited to below 570¡ãF, as prolonged exposure to high temperatures can make the material brittle.
