2 inch duplex steel slip-on flanges

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.

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.

Long weld flanges help with high pressures and the need for a long, tapered hub is the most common use for weld neck flanges. When ordering, it is most important to specify the pipeline plan that will be used. This flange is ideal for use in environments involving extreme temperature fluctuations and excessive handling and bending.

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.

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.

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

A182 F51 Duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance.

Long weld flanges help with high pressures and the need for a long, tapered hub is the most common use for weld neck flanges. When ordering, it is most important to specify the pipeline plan that will be used. This flange is ideal for use in environments involving extreme temperature fluctuations and excessive handling and bending.

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.

These high-strength flanges securely seal a range of plumbing modules. The multifunctional flange shows good stability and exhibits enhanced resistance to chloride pitting in marine applications. With standard welding procedures, Super Duplex Flanges can be easily welded to different piping modules.

Both ASME B16.5 and ASME B16.47 have endorsed pipe flanges made from a series of duplex stainless steel grades.

The austenitic portion of this alloy is the reason why A182 Super Duplex Flanges resist pitting, crevice, and general corrosion. Typically organic acids such as acetic and formic acids cause uniform corrosion in many steel alloys. Molybdenum, which contains a high chromium content, makes UNS S32750 butt weld flanges resistant to corrosion in environments containing these acids.

Duplex steels were introduced to the market as a means to address the problems associated with stress-related corrosion cracking caused by chlorine solutions. The chemical composition of the duplex flange material also makes flanges less prone to chlorine-induced pitting corrosion. These alloys are less expensive than nickel-based steels.

Duplex steel Werkstoff No 1.4462 threaded flanges also cannot be used below -50¡ãC as it will cause a ductile to brittle transition. Duplex UNS S32205 Orifice Flange has a tensile strength of 1,16,000 psi 800 MPa. Whereas the duplex SAF 2205 socket weld flange has a yield strength of 80,000 psi 550 MPa. The 2205 Duplex Butt Weld Flange is a low carbon version that is not affected by sensitization and avoids carbide precipitation in welding applications.

Duplex 2205 and Super Duplex 2507 stainless steel butt weld flanges feature a high yield strength that is twice the annealed yield strength of typical austenitic stainless steels such as 304 and 316 stainless steel butt weld flanges. Because of this, Duplex 2205 and Super Duplex 2507 steels are some of the most common duplex grades used for butt weld flanges, with Super Duplex 2507 butt weld flange being the more corrosion resistant grade of the two.

It is needed when the neck needs to be lengthened. Duplex steel flanges act as extensions. Duplex steel flanges are used in the chemical and petroleum industries for residential and commercial buildings. Duplex steel flanges perform well under pressure levels and temperature fluctuations. Long butt weld flanges are available in various lengths, sizes and dimensions according to customer needs.

ASTM A182 F51 flanges refer to pipe flanges made from the forged duplex stainless steel grade UNS S31803 for use in pressure systems.

Duplex 2205 is a nitrogen enhanced duplex stainless steel designed to solve common corrosion problems encountered with 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic (such as 304 stainless steel) nor purely ferritic (such as 430 stainless steel). The structure of 2205 duplex stainless steel consists of a pool of austenite surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. 2205 is often referred to as the workhorse grade and is the most widely used grade in the duplex stainless steel family.

The range of Duplex Steel 2205 Orifice Plate Flanges covers all standard materials, sizes, grades and specifications.

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.

Based on composition, materials can be classified as Standard Duplex, Super Duplex, and Lean Duplex. Duplex steel flanges are suitable for high pressure, high temperature and highly corrosive applications. Duplex is also cost effective and has recently been used and replaced by other material grades.

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.

Sizes range from ?” to 48″. Pressure ratings range from 150 psi to 2500 psi and more. There are also different types of flanges for different applications. ASME SA182 F51 RTJ flanges have two rings as two halves that are joined at the joint by welding.
