Duplex Steel Flanges

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 ASTM A182 UNS S32750 Slip On Flanges are good to use with seamless pipes.

They have a design that allows for the pipes to pass through the flange and locate the correct point for connection. The ASTM A182 grade F53 WNRF Flange has a welded neck raised face.

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.

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.

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.

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

It is also exceptionally resistance to chloride SCC. Flanges are supplied with pitting resistance equivalent that is assuring very good pitting corrosion resistance.

We are manufacturers of ASTM A182 Duplex UNS S32750 / S32760 Flanges show enhanced pitting corrosion resistance in saline environments, brackish waters, bleaching operations, and selected food processing applications.

Offshore marine engineering plants need compenents that meet their rugged demands, components that have mammoth strenght but are light weight.

We are suppliers of WNR 1.4410 Super Duplex Steel Weld Neck Flanges with matching stub-ends that withstand alkalis under higher temperatures.

Super Duplex UNS S32760 Reducing Flanges have a strengthened microstructure, a result of added Nitrogen, allowing fabrication of thin and low-weight flanges that are easy on the pocket.

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.

Super Duplex stainless for e.g. alloy UNS S32750, has a mixed microstructure of both austenite as well as ferrite in an equal or 50/50 ratio.

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

This is the main reason why Super Duplex Flanges note an improvement of tensile strength over ferritic and austenitic steel grades.

The material has high strength and corrosion resistance. The A182 F53 material is used to make flanges ranging from 1/2 inches to 48 inches under different standards such as ANSI, ASME, DIN and other international standards.

The primary difference between standard duplex grades and the Super Duplex Steel Flanges Material is that Super duplex has a higher content of both molybdenum and chromium their alloy.

There are different pressure ratings for the flanges based on the system of measurement. Under the ANSI standard, the pressure classes range from class 150 through class 2500.

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

There are SA 182 F53 S32750 Blind Flanges, socket weld flanges and weld neck flanges in this range of material. The different flanges are used in different applications set ups.

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.

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

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

Duplex 2205 flanges combine the qualities of stress corrosion cracking resistance and high strength derived from being a ferritic alloy along with its austenitic fabrication capabilities.

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

2205 flange has good sulfide stress corrosion resistance and high strength and good fatigue resistance.

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

In comparison to SS316, Duplex 2205 has been tested under reverse bending stresses at room temperature. The results show that the fatigue limit/yield strength is about twice as high for Duplex 2205.

Duplex 2205 flanges offer good sulfide corrosion resistance, as well as chloride pitting and crevice corrosion resistant superior to 317L.

An austenitic-ferritic stainless variant with a higher stress corrosion cracking resistance in comparison to regular austenitic 304 and 316 stainless, but with a lower toughness and impact strength.
