A SA182 duplex steel orifice plate flange dn25 pn10

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.

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.

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.

Butt weld flanges are the most popular type of high pressure pipeline flange. The tapered hub design of butt weld flanges provides an extremely strong connection, and butt weld flanges can be manipulated and bent repeatedly without compromising material and/or connection quality . Butt weld flanges also have the advantage of being highly resistant to extreme high and low temperatures.

To be able to form a piping system, pumps, pipes, valves and various other equipment are connected together by so-called flanges. These flanges are almost always threaded or welded. Flanges are great because they can be easily inspected, cleaned, or any desired modification.

Super Duplex Steel Butt Weld Flanges are inherently non-magnetic. Austenitic stainless steel also contains nickel, molybdenum, copper, niobium, aluminum, etc. in chemical composition. It shows similar austenite and ferrite grades.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

Compared with austenitic stainless steel, F51 duplex stainless steel has twice the compressive strength, and compared with 316L and 317L, the designer can reduce its weight.

Corrosion Duplex 2205 flanges provide the industry with an improved stainless steel corrosion solution with good sulfide corrosion resistance and better resistance to chloride pitting and crevice corrosion than 317L.

These grades are excellent for fixed service simple flange connections, but slightly less so when forming a complex metallic shape. Fortunately, the workability of duplex into complex and rounded structures is less of an issue in structural steel given the wide preference for simple mild steel in non corrosive applications.

The formation of intermetallic phases such as sigma phase in duplex steel flange flanges occurs in the temperature range of 600¡ãC – 1000¡ãC, and the decomposition of ferrite occurs in the temperature range of 350¡ãC – 500¡ãC ( 475¡ãC embrittlement).

The yield strength of duplex stainless steel is twice that of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more cost-effective than 316, 317L.

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.

It has the nominal composition of 22Cr-5Ni-3Mo-N with P number 10H.

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

UNS S32205 ASTM A182 flanges have good resistance to chloride pitting and crevice corrosion due to a combination of chromium, molybdenum and nitrogen. The exotic duplex 2205 flange alloy is used in oil and gas exploration, this alloy is also used in the chemical processing sector.

For standard austenitic stainless grades (such as 304 and 316), SCC can be a problem in environments with humidity and high temperatures or with certain chemicals such as chlorides. Therefore, duplex blind flange suppliers often supply them to industries such as oil and industrial, gas, petrochemical and marine industries.

Duplex Steel UNS Grade S32205 Duplex Steel is resistant to chloride environments and sulfide stress corrosion. Its yield strength is approximately twice that of standard austenitic stainless grades. Duplex steel UNS S32205 flanges are extremely durable and can also be easily installed to any size thanks to the different shapes and sizes available.

The astm a182 f53 vs f55 can come in different diameters ranging from ? inches to 48 inches with different pressure classes ranging from class 150 through class 2500.
