Alloy steel carbon steel duplex steel forged flange ring

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.

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.

Robust modules resist acid pitting in marine systems. Duplex flanges effectively connect different piping modules in the system and affect the flow of fluids or gases. This grade has higher strength and crack resistance than common austenitic grades. These flanges also have excellent ductility and can be welded in place using standard procedures.

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.

At this temperature, duplex steel flanges over 300 degrees Celsius are still protected from embrittlement due to corrosion. Duct capability is also excellent at low temperatures. Fabrication is done only with tools assigned to stainless steel materials. Must be properly cleaned before use. This is done to protect the stainless steel from cross-contamination of the corroding metal.

Duplex steel flanges are hardened alloys that are also very corrosion resistant. The microstructure of this steel consists of a mixture of ferrite and austenite phases. Therefore, they have the characteristics of both ferritic and austenitic stainless steels.

Duplex stainless is a mixed microstructure of austenitic and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.

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.

These flanges can be hardened by heat treatment. The application industries of duplex steel flanges are; they are used in offshore oil drilling companies, aircraft exhaust manifolds, petrochemicals, power generation, gas processing, pharmaceuticals, specialty chemicals, burner pipes and spiral welded pipes for fuels, pharmaceutical equipment, Heat exchangers, and seawater equipment. Duplex steel flanges are available in a variety of designs such as sleeve, butt weld, blind, threaded, lap joint and socket weld.

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.

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.

ASTM A182 Grade F51 is the standard duplex stainless steel and is also called ¡°duplex 2205¡± or ¡°alloy 2205¡±.

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 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.

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.

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.

ASTM A182 F53 flanges refer to flanges made from super duplex stainless steel 2507 (UNS S32750) by a hot forging process.

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.

2205 Duplex Steel consists of a two-phase microstructure of ferrite and austenite. When it comes to the chemical composition of 2205 duplex steel flanges, they mainly contain 22% chromium, 3% molybdenum and 5-6% nickel in the form of alloyed stainless steel.

They help modify and even clean these process systems. The corrosion resistance and tensile properties of duplex steel sliding flanges are amplified compared to most stainless steel flanges.

Compared to austenitic stainless steels, duplex stainless steels have higher tensile and yield strengths and significantly improved resistance to chloride SCC (stress corrosion cracking). They also exhibit higher toughness than ferritic stainless steels.

Duplex stainless steel flanges, these flanges have some excellent properties such as light weight, robust construction, accurate dimensions and more. We also offer these products in different grades such as Duplex Flanges, Duplex Flanges, Super Duplex Flanges and Super Duplex Flanges.

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.

Butt welding flanges are drilled (machined), and the wall thickness of the flange is the same size as the matching pipe. The lighter the tube, the larger the diameter, and conversely, the heavier the tube, the smaller the diameter. Our range of butt weld flanges, butt weld flanges are typically used for high pressure, low temperature or high temperature.

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.

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

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

Duplex steel flange also offers Good weldability and workability, High energy absorption and Low thermal expansion.

Duplex stainless steel S31803/S32205/2205 flanges are supplied with good sulfide stress corrosion resistance, high strength and excellent impact toughness. These dual phase steel S31803 slip flanges are chemically balanced to produce a microstructure of approximately 50/50 ferrite to austenite ratio.

This increase in alloyants is what gives the super duplex stainless steels greater corrosion resistance properties.

Duplex stainless steel pipe flange suppliers recommend this stainless steel grade for many operations because the range of stainless steel grades is similar to the corrosion resistance range of austenitic stainless steel grades, i.e. from Type 304 or 316 to 6% molybdenum stainless steel.

This means that it derives its superior ductility and corrosion resistance from the austenite in the alloy, and the Werkstoff No 1.4462 BLRF flange has higher strength and hardness, both of which are ferritic part.
