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 .

The S31803 fastener series demonstrates the properties of ferritic and austenitic stainless steels. These fasteners exhibit excellent resistance to crevice corrosion, stress corrosion cracking and pitting corrosion in harsh environments. In addition, these are excellent in resistance to chloride and sulfide stress corrosion environments.

Super Duplex SAF 2507 is a really strong material with great corrosion resistance.

The granular structure of duplex is a ferrite-austenite hybrid with a superior strength to weight ratio in comparison to 304 or 316. It balances the weldability of an austenitic with a pure ferritic and retains decent mechanical toughness in applications with exposure to colder ambient temperatures.

S31803 has been supplemented by S32205 (F60) which dual conforms to S31803 but has a higher minimum N, MO, NI and Cr which guarantees a better corrosion resistance.

Duplex¡¯s premium mechanical and chemical properties are slightly offset by its difficulty in formability.

Duplex describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase.

There are components of duplex 2205 fasteners available such as studs, set screws, bolts, washers and nuts. Whenever you specifically consider duplex stainless steel 2205 gaskets, it can be of great benefit for different types of critical industrial applications often found in harsh environments. Almost all types of 2205 stainless steel gaskets will provide a never-ending supply and excellent range of service for different applications such as valves or nuclear, seawater, offshore buoyancy and petrochemical, pumps, etc.

Super Duplex are trace amounts of carbon, phosphorus, sulfur, silicon, nitrogen, and copper. It has great general consumption resistance, proposed for applications up to 600¡ã F, and low rate of warm development.

Pipes that are used in the conveyance of such media need to be durable on account of the stress caused by the flow. Hence, many suppliers recommend using the Duplex Stainless Steel Pipe for the qualities they offer.

The standard austenitic steels like 304 (1.4301) and ferritic steels like 430 are relatively easy to make and to fabricate. As their names imply, they consist mainly of one phase, austenite or ferrite. Although these types are fine for a wide range of applications, there are some important technical weaknesses in both types.

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

This heat treatment performed on the Duplex 2205 Pipe must be keeping with accordance to the specified temperature and quench conditions.

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

The yield strength is also higher, allowing component designers to reduce section size for load-bearing applications.

Compared with ferritic stainless steel and austenitic stainless steel, duplex stainless steel pipe has good welding performance. It is neither like the welding heat affected zone of ferritic stainless steel, because of the grain coarsening, the plastic toughness is greatly reduced, nor like austenitic stainless steel, it is more sensitive to welding hot cracks.

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 stainless steels are approximately 50% ferrite and 50% austenite for optimum strength and corrosion resistance.

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

The round and hollow pipes are usual ones. In addition to the Duplex Stainless Hollow Pipes and the Duplex Steel Round Pipes there are square, rectangular and hexagonal pipes available in the market.

2507 has a higher chromium and molybdenum content which gives the super duplex greater corrosion resistance than other standard duplex grades.

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.

2205 is also more formable under pressure than other ferritic grades. The greater toughness of this grade also outweighs most of its concerns.

Duplex stainless steel offers excellent resistance to corrosion and very high mechanical strength. The high corrosion resistance of duplex stainless steel ensures significantly more uptime than carbon steels and conventional stainless steels, while the mechanical strength allows for lighter constructions, a more compact system design and less welding.

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