The SA 182-F51 S31803 comes under ASME B16.47, B16.48 and B16.5 standards with sizes ranging from 1/8 NB to 48NB.

Duplex 2205 bolts have a ductile to brittle transition at -50¡ãC and also become brittle at 300-1000¡ãC, so a temperature of -50¡ãC to 300¡ãC is recommended. Exposure to above 300¡ãC will not only cause embrittlement of 2205 bolts, but will also reduce corrosion resistance.

Duplex steels are also magnetic, a property that can be used to easily distinguish them from ordinary austenitic stainless 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.

2507 is used for Chemical process industries, heat exchangers, vessels, and piping, desalination plants, high pressure RO-plant and seawater piping, mechanical and structural components, high strength, corrosion-resistant parts.

Super Duplex 2507 Lock Washers has excellent corrosion resistance in marine environments.Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener.

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

Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

2507 (UNS S32750) is a super duplex stainless steel designed for applications which require exceptional strength and corrosion resistance. 2507 is a 25% chromium, 4% molybdenum, and 7% nickel alloy resulting in excellent resistance to chloride pitting and crevice corrosion attack.

UNS S31803 Bolted Fasteners are used in marine, agricultural, chemical, construction, shipping, aviation, nuclear and industrial equipment.

Zeron 100 is highly resistant to corrosion in a wide range of organic and inorganic acids. The copper content gives excellent resistance to corrosion in many oxidising acids. This alloy is also highly resistant to strong alkalis.

Super Duplex 2507 cannot be strengthened by heat treating. Annealing is performed at 1920¡ãF – 2060¡ãF (1049¡ãC – 1127¡ãC), followed by rapid cooling.

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.

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.

2205 stainless steel sheet has high tensile stress and low thermal expansion and can be used in cargo holds, trucks and ships as sheet.

Duplex2205 washers are dual phase austentic-ferritic duplex fasteners manufactured from alloy containing chromium, nickel alloy and molybdenum with restricted carbon content and minimum PREN35, SAF2205 fasteners have excellent corrosion resistance and high strength.

This type of steel is excellently resistant to shearing as a result of stress corrosion, high thermal conductivity and a low thermal expansion coefficient.

Super Duplex UNS S32760 is one of the most common super duplex grades on the market. UNS S32760 is a duplex stainless steel designed for use in corrosive chlorine-containing environments, with the addition of W and Cu compared to UNS S32750.

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.

With its myriad applications, the process industries are always in pursuit of highly reliable materials. Duplex Stainless Steel Piping is widely endorsed by plant operations management and maintenance specialists who appreciate their toughness and ability to withstand the very aggressive fluids inherent in the process.
