We are manufacturers of ASTM A182 Duplex UNS S32750 / S32760 Flanges show enhanced pitting corrosion resistance in saline environments, brackish waters, bleaching operations, and selected food processing applications.

Duplex 2205 flanges combine the qualities of stress corrosion cracking resistance and high strength derived from being a ferritic alloy along with its austenitic fabrication capabilities.

Super Duplex Steel Flanges are ideal for service in severely corrosive environments such as offshore and marine applications. It is also particularly resistant to chloride SCC. Flanges provide equivalent pitting resistance, ensuring very good pitting resistance. All of our product ranges are strength tested, including pitting corrosion testing, toughness testing, chemical and mechanical testing, macro and micro testing, and more.

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

Duplex steel flanges are light in weight and perfect in size and other parameters. These are used in the manufacturing industry. In this case, stainless steel is used, so the corrosion resistance of this product is very good. Duplex blind flanges have the characteristics of high strength and are widely used in petrochemical, electric power and other industries. This needs to be used at some specific temperature as it can become brittle at high temperatures.

Some dual-phase steel S31803 butt weld flanges have good oxidation resistance at high temperatures, but tend to become brittle at temperatures above 300 degrees Celsius, and only 2 hours exposure to 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.

We are one of the largest producers of duplex steel sliding flanges with good fatigue strength and high corrosion resistance. 2205 Duplex Steel Blind Flange is also known for its various mechanical properties, such as excellent resistance to cracking, pitting, and corrosion in harsh environments.

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.

Molybdenum increases resistance to pitting and crevice corrosion. However, its content in duplex stainless steels is generally limited to less than 4% because Mo is also a ferrite former and can lead to unwanted intermetallic phases. Nitrogen improves resistance to pitting and crevice corrosion.

Duplex stainless steel S31803/S32205/2205 flanges are supplied with good sulfide stress corrosion resistance, high strength and excellent impact toughness. These dual phase steel S31803 slip flanges are chemically balanced to produce a microstructure of approximately 50/50 ferrite to austenite ratio.

The raised face allows for the flange to have more bolt holes and connection surface while the welded neck grips the pipe in place. The applications are oil and gas, petroleum, petrochemical and other industrial applications.

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.

The duplex structure results in improved stress-corrosion cracking resistance, compared with the austenitic stainless steels, and improved toughness and ductility, compared with the ferritic stainless steels.

ASTM A182 F53 Super Duplex Flanges available with rating class of 150#, 300#, 400#, 600#, 900# and 1500# in sizes NPS 1/2 to 24.

Super Duplex Flanges are highly weldable. This alloy can be easily welded by various welding operations. These super duplex flanges are known for their high fatigue strength and provide high strength at moderate temperatures in the lower temperature range.

Duplex stainless steel flanges, these flanges have some excellent properties such as light weight, robust construction, accurate dimensions and more. We also offer these products in different grades such as Duplex Flanges, Duplex Flanges, Super Duplex Flanges and Super Duplex Flanges.

Using UNS S31803 Duplex Steel Pipe Flanges ensures high performance, higher corrosion resistance and longer service life. Due to the dual nature of austenitic and ferritic microstructures present in equal proportions, the dual phase steel RTJ flange material inherits the properties of both steels.

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.

The ASTM A182 F53 UNS S32750 Flange comes under the ASTM A182 specification for high temperature and high pressure services.

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 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.

In comparison to SS316, Duplex 2205 has been tested under reverse bending stresses at room temperature. The results show that the fatigue limit/yield strength is about twice as high for Duplex 2205.

Duplex stainless steel grades are named duplex because these duplex flange equivalent grades have a two-phase microstructure. This two-phase microstructure consists of ferritic and austenitic stainless steel-like grains. As the name suggests, the duplex construction gives this duplex stainless steel socket weld flange material a variety of attractive properties.

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.

ASTM A182 F53 flanges refer to flanges made from super duplex stainless steel 2507 (UNS S32750) by a hot forging process.

There are different types of flanges such as slip on flanges, socket weld flanges, forged flanges, blind flanges, reducing flanges and many by their functions.

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

Stainless steel grades with more than 12% chromium in the alloy are resistant to the effects of oxidation. In the case of super duplex stainless steel 2507, its alloy contains 25% chromium, which improves oxidation resistance even at high temperatures.
