105 duplex steel flange for reducer customized

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.

Super Duplex Flanges use pure quality alloys with mixed austenitic and ferritic microstructures and high molybdenum and chromium content. This superior chemical composition provides superior resistance and increased strength. The products we manufacture are used in a wide variety of applications and industries. These flanges are highly resistant in corrosive, acidic and reducing environments.

Weld-neck flanges get their name from the flange necks that are welded to the end of a piping system. It is designed to transfer stress to the pipe, thereby reducing high stress concentrations at the bottom of the flange. Butt weld flanges cost more because of their design and engineering and the added material.

Some 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. These dual phase steel S32205 ring joint flanges also feature high corrosion and erosion fatigue performance as well as lower thermal expansion and higher thermal conductivity than certified.

The ASTM A182 F51 flanges refer to standard or non-standard flanges manufactured in accordance with ASTM A182 Grade F51, which is designated with UNS number S31803.

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.

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

The combination of chromium, molybdenum and nitrogen gives 2205 good resistance to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. 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, and Citizen Metals has been actively involved in ensuring the best possible quality for our customers.

Super duplex steel flanges are very good for servicing a severe corrosive atmosphere like offshore and marine 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.

Duplex 2205 is characterized by high resistance to chloride stress corrosion cracking, chloride pitting and crevice corrosion resistance, good general corrosion resistance, good sulfide stress corrosion resistance, high strength and good weldability and workability.

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

S31803 has been supplemented by S32205 which has a higher minimum N, CR and Mo.

This alloy is especially useful in the -50¡ãF/+600¡ãF temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some restrictions, especially when used in welded structures.

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.

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.

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.

These super duplex steel UNS S32760 flanges are technologically advanced using premium materials under the guidance of skilled experts. They have outstanding features such as resistance to plastic deformation, wear resistance, chipping resistance, and good machinability.

These high-strength flanges securely seal a range of plumbing modules. The multifunctional flange shows good stability and exhibits enhanced resistance to chloride pitting in marine applications. With standard welding procedures, Super Duplex Flanges can be easily welded to different piping modules.

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.

The applications include high corrosive applications including acidic applications due to the material composition.

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.

Dual-phase steel butt-welded raised face flanges provide excellent and consistent machinability for increased cutting speeds, reduced tool wear and set-up time.

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.

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

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 flanges are made of a special stainless steel with austenitic and ferritic metallurgical features in its microstructure. These are magnetic steels with high corrosion resistance and work hardening.

Super Duplex 2507, UNS S32750, is a duplex stainless steel especially suitable for environments such as warm chlorinated seawater and acidic chlorinated media. It has similar properties to Duplex 2205 but is more corrosion resistant and performs well in moderately corrosive environments.

These dual phase steel S32205 ring joint flanges also feature high corrosion and erosion fatigue performance as well as lower thermal expansion and higher thermal conductivity than certified. Our Duplex 2205 Socket Weld Flanges are highly resistant to pitting and crevice corrosion, perform well in most corrosive environments, and have good weldability.
