Duplex Steel Flanges

Duplex Steel Flanges are specific fittings used in the piping industry which has features of both austenitic and ferritic stainless steel. Offering features such as great tensile strength, high corrosion resistance and high durability, Duplex Steel Flanges are in high demand in the market. This metallurgical structure makes them perform well in conditions that are difficult to handle, such as stress corrosion cracking and pitting. Thus, they can be used in applications where reliability and durability are important. 

Features of Duplex Steel Flanges 

Duplex Steel Flanges offer several key features: 

• High Strength: The flanges are made from duplex steel, which contains both ferritic and austenitic stainless steel. This makes them possess high tensile and yield strength and the ability to work under high pressure. 
• Corrosion Resistance: Duplex steel flanges possess good resistance against stress corrosion cracking, pitting as well as crevice corrosion. 
• Ductility and Toughness: Duplex steel flanges have good ductility and toughness even at low temperatures and therefore are likely to last longer and perform well under difficult conditions. 
• High Resistance to Abrasion: The duplex steel flanges' structure is better suited for withstanding wear and tear, and it is useful where abrasive material is used or is tough to handle. 
• Low Thermal Expansion: Duplex steels have less coefficients of thermal expansion, which means that flange deformation is minimised under thermal cycling. 
• Good Weldability: Duplex steel flanges are weldable by conventional methods of welding and this makes it possible to incorporate the flanges into the systems easily. 

Duplex Steel Flanges have several benefits making it suitable for use in industrial applications. 

Uses of Duplex Steel Flanges 

Duplex Steel Flanges are used in various applications because of the following properties. Common applications include: 

• Oil and Gas Industry: Duplex steel flanges are used in pipelines, valves, and equipment that comes in contact with high pressure and high temperature fluids and gases. 
• Marine Engineering: Duplex steel flanges are applied in seawater systems and other marine applications such as seawater cooling systems, ballast systems and offshore platforms. 
• Power Generation: Duplex steel flanges are used in power plants for essential parts of the plant, including steam lines, condensate systems and high-pressure piping systems. 
• Pulp and Paper Industry: Chemical pulping and bleaching systems employ duplex steel flanges. They are intended for the use of aggressive chemicals and high-pressure processes so that the processing is optimally done in such conditions. 
• Desalination Plants: Duplex steel flanges are used in desalination processes like high pressure pumps, seawater intake systems and pipelines. 
• Construction: Duplex steel flanges are used in structures such as bridges and buildings where the strength and endurance of the material are paramount. 

Duplex steel flanges are perfect for various industrial applications.
