Super Duplex S32750 Flange ANSI B16.5 SUPER DUPLEX S32750 FLANGES

It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing.

Higher chromium, molybdenum and nitrogen content results in a Pitting Resistance Equivalent Number (PREN) > 40, providing superior pitting and crevice corrosion capabilities to austenitic and duplex stainless steels in virtually all corrosive media, and critical pitting temperature Above 50¡ãC .

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

It is a super duplex alloy, so heat resistance is also what Super Duplex 2507 rods are capable of. River or sea water often contains highly corrosive chemicals containing sulfur or chloride ions, and materials such as the 2507 Super Duplex Round Bar can withstand these chemicals.

The Duplex Steel Pipe gets its name from the dual nature present in the microstructure of the alloy. Duplex Stainless Steel Seamless Pipe have good mechanical characteristics and can be used in an as welded condition. Considered to be superior in comparison to austenitic alloys ASTM A312 TP304 or ASTM A312 TP316, the Seamless Duplex Pipe offers much better resistance to corrosion.

Duplex stainless steel fasteners are available in Super Duplex, Lean Duplex and Standard Duplex grades, each with specific properties for differenut applications.

2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.

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

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.

Super Duplex Pipe Suppliersis known to have better pressure erosion, splitting obstruction and mechanical properties than some other kind of steel.

Super Duplex tubes for the increasing hostile temperature and operating environments – where maximising operating efficiency demands total product reliability. 2507 Super Duplex Products therefore have very his corrosion cracking resistance and tensile strength.

Zeron 100 Threaded Rod are available in hot forged,cold forged and bar stock machined conditions depending upon the order quantity.SA 182 F55 is a forging grade of Alloy 32760 or UNS 32760 which is highly resistant to crevice corrosion and pitting alloy for variety of corrsives. It is 22% chromium duplex stainless steel.

Duplex 2205 is a nitrogen-enhanced duplex stainless steel designed to solve common corrosion problems encountered with 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic (such as 304 stainless steel) nor purely ferritic (such as 430 stainless steel).

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

The pressure capacities of the flanges can also be expressed in pressure numbers. The astm a182 f53 uns s32750 flange types come in pressure numbers ranging from PN6 through PN64.

ASTM A1082 specification alloy S31803 fasteners have higher pitting and crevice corrosion than stainless steel alloy 316. Due to its higher corrosion resistance, alloy grade UNS S31803 is able to exhibit better fatigue strength than other commonly used austenitic stainless steel grades in environments containing corrosive media.

UNS S32205 nuts (also known as S31803) are manufactured from high-grade duplex 2205 stainless steel. Since this material is composed of at least 22% chromium, 6% nickel and 3% molybdenum it can withstand several unique types of environmental inflexibilities that other metals cannot such as corrosion, cracking, erosion, pitting and more. Super duplex stainless steel 2205 nuts also provide twice the mechanical strength compared to standard stainless steel.

The dual phase steel / super duplex steel stainless steel pipe is a kind of stainless steel with high strength and high corrosion resistance, which has the properties of austenitic stainless steel and ferritic stainless steel. Generally, when the carbon content is low, the Cr content is 18% ~ 28%, and the Ni content is 3% ~ 10%. Some steels also contain Mo, Cu, Nb, Ti, N and other alloy elements.

Alloy 2205 duplex stainless steel is an alloy developed from the initial Super Duplex Stainless Steel. It is supplied in the solution annealed condition.

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.

These grades of super duplex stainless steel fasteners are used when applications require excellent corrosion resistance and strength. Composed of nitrogen, molybdenum and chromium, they have excellent resistance to crevice corrosion and chloride pitting.

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 steel alloys have the properties of austenitic and ferritic stainless steels. This is because they have nearly equal proportions of dual microstructural phases (austenite and ferrite) in the annealed condition.

Duplex ( UNS S31803 / S32205 ) rods, also known as steel rods (ASTM A276 / ASTM A479 ), have excellent corrosion resistance. Stainless steel rods/stainless steel rods ( en 1.4462 ) are resistant to intergranular and crevice corrosion.

There are different types of flanges such as slip on flanges, socket weld flanges, forged flanges, blind flanges, reducing flanges and many by their functions.

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.

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

Super Duplex 2507 Equal tees are the most common fittings.

Duplex 2205 alloy is composed of high chromium and low or moderate nickel conutenut.

The material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. This alloy has good weldability and very high mechanical strength.

The higher percentage of chromium in the alloy of duplex stainless steel seamless pipe makes it resistant to oxidation.
