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 presence of ferrite in the duplex 2205 welded pipe is what provides for an enhanced performance of this stainless steel grade in caustic media containing environments.

The 2205 Duplex Stainless Pipe produced in accordance to ASTM A790 specification could be constructed by either a seamless construction or an automatic welding process.

Duplex variety stainless steels work well in those applications which contain a high concentration of chlorine. Chloride ions, which are normally detrimental to conventional stainless steels, do not cause any damage to the much stronger Duplex Stainless Steel Pipe. The chemistry of this steel ensures better performance with higher mechanical properties in comparison to austenitic stainless steel pipes.

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.

UNS S32750 ( F53 / 1.4410 / Alloy 2507) has a lower coefficient of thermal expansion and higher thermal conductivity than austenitic steel, and is suitable for operating temperatures up to 300 ℃.

With an increased chromium content compared with F51 it offers improved pitting corrosion resistance.

Duplex stainless steels have a mixed microstructure of austenite and ferrite, the aim being to produce a 50/50 mix, although, in commercial alloys, the mix may be 40/60 respectively.

Duplex 2205 stainless steel plate has excellent corrosion resistance, much higher than grade 316. It can withstand localized corrosion types such as intergranular, pitting and crevice.

The combination of chromium, molybdenum and nitrogen convey the good resistance of 2205 to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environments.

ASTM A240 UNS S32750 plate is suitable for high tension and high corrosion environments.

This provides the flanges with high corrosion resistance and higher mechanical properties. Please contact us for your orders of F53 flanges.

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.

Duplex pipes are stainless pipes containing the high amount of chromium and minimum amount of nickel. Duplex pipes provide great strength and resistance to corrosive environments. Duplex pipes are used in desalination plants, heat exchangers, and marine processes.

Super Duplex UNS S32750 bar has excellent resistance to stress corrosion cracking in chlorine containing environments. After heating to a solution treatment temperature of 1080¡ãC to 1120¡ãC, quenching is required.

2507 Duplex is highly resistant to uniform corrosion by organic acids such as formic and acetic acid.

ASTM A240 UNS S32760 Plate is a super duplex stainless steel alloy for specific applications.

El uso de tuberias sin costura ASTM A790 UNS S32205 (sin costura y soldadas) es adecuado para aplicaciones generales, pero la solucion principal que brindan es el agrietamiento por corrosion relacionado con la tension.

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

The flange a182 f53 can also differ in the face type as flat face, raised face and ring type joint flanges.

The UNS S32750 standard of Pipe Fittings consists of 25% chromium, 4% molybdenum, and 7% nickel. The UNS S32750 Pipe Fittings have a 50-50 microstructure of ferritic and austenitic steel grades with improved strength.

Duplex 1.4462 round bars also have low thermal expansion and high thermal conductivity as well as high corrosion and erosion fatigue properties compared to austenite. The corrosion resistance of duplex 2205 is almost twice that of other austenitic stainless steels.

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.

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.

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

The 2205 gasket is known as a duplex stainless steel gasket because it has a combination of ferrite and austenite and can be made into fasteners due to its high corrosion resistance. It has higher corrosion resistance than 316 stainless steel and is also highly resistant to stress corrosion and chloride cracking. 2205 has been determined to be cost effective because it is only 5% nickel and is significantly less expensive than Hastelloy C276 fasteners.

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.

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

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.
