What are Duplex Steel Flanges?
Duplex Flanges are made of two Different Alloys, one is austenitic stainless steel, & the other is a ferritic one. Their chemical compositions provide excellent weldability & toughness. In addition, the corrosion resistance is also superior. In addition, however, they are used as socket weld flanges or ring joint flanges. Duplex Steel Flanges are suitable for harsh environments, including chloride-containing media.
Duplex Steel Flanges are used in a wide variety of applications. They have many advantages over other types of flanges. These include good corrosion resistance, high mechanical strength, & ductility. Moreover, they are made from a material that does not need a coating or spooling to weld. This means that they can be used at a lower temperature.
In addition, Duplex Steel Flanges are useful when high heat pressure is required. This property makes them particularly important in structural applications. Also, they are less expensive than nickel-based alloys. For example, Duplex Steel Flanges can be used at temperatures as low as -50 degrees Celsius.
Duplex Flanges are used in a variety of applications. They provide excellent corrosion resistance while offering high strength & formability. Duplex 2205 Flanges are one of the most commonly used types. They are often used in pulp & paper plants industries. In addition, their properties make them suitable for marine environments. Due to the combination of properties of both steel classes, Duplex Steel is a strong material with good weldability & resistance to corrosion. As a result, it is used in various types of equipment, such as seawater desalination plants, power generation equipment, chemical tankers, & solvent treatment equipment.
With their ability to withstand pressure, duplex flanges are used in various applications, including oil & gas exploration. They are also used in a number of architectural applications. In addition, they are used in thermal power plants & chemical plants. In addition, duplex flanges are characterized by their low nickel content. Compared to austenitic stainless steels, which have a higher nickel content, duplex steel has a much lower nickel content. This means that duplex flanges are less expensive than nickel-based steels.
Kencotube is one of the leading Manufacturers, Suppliers & Stockiest of high-quality Duplex Steel Flanges. Duplex Steel Slip On Raise Face Flanges has high corrosion resistance in chloride-containing media, including seawater, which makes the grade ideal for use in deep-water umbilicals & a range of other oil & gas applications. As medium-alloy steel, Duplex Steel Blind Raised Face Flanges have superior corrosion resistance in most media compared to the standard austenitic stainless steel ASTM 316L & twice the mechanical strength. Duplex Steel Pipe Flanges is hyper steel for service in highly corrosive conditions, requiring very high mechanical strength.
Duplex Steel Weld Neck Raised Face Flanges offer excellent & consistent machining properties for increased cutting speeds, reduced tool wear, & set-up times. The formation of intermetallic phases in Duplex Steel Plate Raised Flanges, such as the sigma phase, occurs in the temperature range 600 Degrees C - 1000 Degrees C & the decomposition of ferrite occurs in the range 350 Degrees C - 500 Degrees C (475 Degree C embrittlement). The basic idea of Duplex Steel Long Weld Neck Flanges is to produce a chemical composition that leads to an approximately equal mixture of ferrite & austenite. Therefore, the chemical composition of Duplex Steel Lap Joint Flanges is balanced to give approximately equal amounts of ferrite & austenite in solution-annealed conditions.
