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.

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 21% chromium content is the key to extreme corrosion resistance and strength of the SA 182 f51 flanges. HT PIPE is a leading supplier and manufacturer of the flanges in various scales, shapes and types.

Duplex flanges are made of a special stainless steel with austenitic and ferritic metallurgical features in its microstructure. These are magnetic steels with high corrosion resistance and work hardening.

The high chromium, molybdenum and nitrogen content of 2205 provides better corrosion resistance than common stainless steels such as 316L and 317L in most environments. This exotic alloy is used in oil and gas exploration and is also used in the chemical processing industry .

Super Duplex Steel 1.4410 Flanges are having low alloying costs as compared to the similar ferritic and austenitic grade along with resistant to corrosion in the chloride-containing atmosphere because of well-enhanced yielding and tensile strength.

Duplex 2205 is characterized by high resistance to chloride stress corrosion cracking, chloride pitting and crevice corrosion resistance, good general corrosion resistance, good sulfide stress corrosion resistance, high strength and good weldability and workability.

Duplex stainless steel pipe flange suppliers recommend this stainless steel grade for many operations because the range of stainless steel grades is similar to the corrosion resistance range of austenitic stainless steel grades, i.e. from Type 304 or 316 to 6% molybdenum stainless steel.

Duplex Steel UNS Grade S32205 Duplex Steel is resistant to chloride environments and sulfide stress corrosion. Its yield strength is approximately twice that of standard austenitic stainless grades. Duplex steel UNS S32205 flanges are extremely durable and can also be easily installed to any size thanks to the different shapes and sizes available.

It reaches the phase balance of austenite and ferrite in roughly same volume fraction.

The different face types have their own advantages in piping 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.

ASTM A182 F53 Flange is a high strength flange that has 550MPa minimum yield strength and 800MPa minimum tensile strength.

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.

Weld-neck flanges get their name from the flange necks that are welded to the end of a piping system. It is designed to transfer stress to the pipe, thereby reducing high stress concentrations at the bottom of the flange. Butt weld flanges cost more because of their design and engineering and the added material.

S31803 has been supplemented by S32205 (F60) which has a higher minimum Ni Cr and Mo.

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).

A secondary task of duplex steel flanges is to facilitate workers who access these systems to clean, inspect or modify them. In general, applications of duplex stainless steel flanges are found in the following industries, namely chemical plants, chemical tankers, thermal power plants, desalination plants, seawater pumps, flue gas desulfurization plants, construction works, and pulp and paper mills. These industries utilize piping systems to transfer media, which often creates some kind of pressure on conventional flanges.

This exotic alloy is used in oil and gas exploration and is also used in the chemical processing industry. Most processing equipment uses Duplex 2205. Also used by industrial storage and transportation units. Pulp and paper digesters, liquid tanks and paper machines also use Duplex 2205. It is ideal for use in marine environments.

This is the main reason why Super Duplex Flanges note an improvement of tensile strength over ferritic and austenitic steel grades.

We offer a complete range of flanges, including slip flanges, socket weld flanges, blind flanges, lap flanges, threaded flanges, butt weld flanges, reducer flanges, and more. Due to a wide range of customer requirements, we offer these super duplex steel UNS S32750 flanges in a variety of sizes.

Offshore marine engineering plants need compenents that meet their rugged demands, components that have mammoth strenght but are light weight.

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

The oxidation resistance of these dual phase steel S31803 butt weld flanges is good at high temperatures, but tends to become brittle at temperatures above 300 degrees Celsius, brittle after only 2 hours of exposure at 475 degrees Celsius. These dual phase steel S32205 ring joint flanges also feature high corrosion and erosion fatigue performance as well as lower thermal expansion and higher thermal conductivity than certified.

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.

S31803 has been supplemented by S32205 which has a higher minimum N, CR and Mo.

The yield strength of duplex stainless steel is twice that of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more cost-effective than 316, 317L.

They help modify and even clean these process systems. The corrosion resistance and tensile properties of duplex steel sliding flanges are amplified compared to most stainless steel flanges.

Chromium, molybdenum, nitrogen and nickel are the most important alloying elements, which have a significant effect on the mechanical, physical and corrosion properties of duplex stainless steels. Chromium is necessary to form a stable chromium passivation film sufficient to protect steel from mild atmospheric corrosion. The higher the chromium content, the better the corrosion resistance.

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

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.
