ASTM A240 Type 2205 Plate is a duplex stainless steel plate that is used extensively in various industries such as chemical processing, oil and gas exploration, and marine engineering. SA 240 GR 2205 Sheet is made from grade 2205 stainless steel, which is a combination of ferritic and austenitic steel.

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

A789 UNS S31803 and UNS S32205 are two grades of duplex stainless steel that are widely used in various industrial applications. These Duplex S31803 Seamless Pipes are known for their excellent corrosion resistance, high strength, and good weldability. A789 is a specification that covers seamless and welded tubes made from duplex stainless steel.

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.

A Super Duplex 2507 Pipe has outstanding resistance to corrosive and oxidative media.

Seamless pipe is not as strong as Duplex SS 2205 welded pipe, but is very dimensionally accurate. Dimensional accuracy is useful in highly sensitive applications where measurement and calculation accuracy is required.

UNS S2750 Super Duplex Fasteners have good weldability and can be joined to itself or other materials by shielded metal arc welding, gas tungsten arc welding, plasma arc welding, flux cored wire or submerged arc welding.

Inhibiting deformation and cracking at high temperatures, the dual phase steel S31803 / S32205 reducer is superior to common steel parts in the chemical industry that are susceptible to chloride stress corrosion cracking. With flue gas desulfurization machinery. Tees such as ASME A182 Duplex Steel S31803/S32205 are known to have good resistance to high toxicity and elasticity.

The Super Duplex 2507 Tube can be used in high-pressure and temperature systems.

ASME SA 479 UNS S32205 Fastener is a corrosion resistant and high strength super alloy that can be used in low temperature ranges up to 1300 degrees Fahrenheit.

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.

Technically, the microstructure of a duplex 2205 tube is approximately 50% ferrite and 50% austenite. As a result, the properties inherited from both categories make this nitrogen-enhanced duplex 2205 seamless pipe ideal for use in industries such as food processing, oilfield piping and heat exchangers, and flue gas desulfurization.

The duplex microstructure gives this grade high strength UNS S32750 a low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300¡ãC.

The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.

The microstructure of ASME SA 479 Duplex Steel UNS S32205 Flat Washers includes a combination of ferritic and austenitic phases. ASTM A479 Duplex Steel UNS S31803 Gaskets have excellent general corrosion resistance in a variety of aggressive chemicals including industrial and seawater acids. Buy duplex stainless steel washers from us at leading market prices.

Super Duplex stainless steel offers the same advantages as its Duplex counterpart. The main difference between the two is that Super Duplex has a higher chromium and molybdenum content, resulting in increased corrosion resistance.

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

On average, duplex stainless steel is about twice as strong as either ferritic or austenitic stainless steels. High toughness and ductility. Duplex stainless steel can be more easily formed under pressure than ferritic grades and also have superior toughness.

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

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.

S31803 Duplex Steel is a 22% chromium duplex (austenitic/ferritic) steel with moderate to good strength and good general corrosion/stress corrosion/cracking resistance.

A182 F53 material displays excellent corrosion resistance.

S32760 Heavy hex nuts are slightly larger and thicker than standard (finished) hex nuts. There are numerous grades and the heavy pattern is typically used for large diameter and high strength bolts.

Alloy 2507 is highly resistant to carbide-related intergranular corrosion.

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

Duplex steel UNS S31803 round bar is widely used for ferritic and austenitic duplex stainless steel bars.

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.

The flanges could also be manufactured as screwed, threaded or forged types. The forged flanges are made from a single piece of raw material. These are also called the cast flanges.

S32750 Seamless Pipes are chromium and molybdenum mixtures with high resistance to pitting. Many industries prefer these Seamless Pipes for their resistance to stress corrosion cracking and crevice corrosion.
