Duplex Flanges

Duplex Flanges are connection supports which look like a plate or a ring with holes for connecting bolts used in a pipeline to connect two major pipelines. The mechanical support provided by Duplex Flanges provides a steady equipment design for the pipeline. For supporting a greater mass, a heavier flange body is required. The structural strength provided by the flange is a great value addition required in the pipeline design. Duplex Flanges Manufacturers are connected to each other with the use of fasteners and gaskets. Flanges are usually welded or screwed. Flanged joints are formed by bolting together two flanges between them to provide a seal. The term “flange” is also used for a kind of tool used to form flanges. Pipes with flanges can be assembled and disassembled easily.

Duplex Flanges can be declassified into various types:
Blind Flange
Weld Neck Flange
Socket Weld Flange
Slip On Flange
Threaded Flange
Lap Joint Flange
Duplex Stainless Steel Forged Flanges

All the above Duplex Flanges can be made in raised face with hub or without hub.

The term “Duplex” has been coined for this kind of stainless steel because it consists of a two phase microstructure consisting of grains of ferritic and austenitic stainless steel and combines many of the beneficial properties of the two types which then helps in providing resistance to localized and uniform corrosion. The chemical composition of the Duplex Steel is balanced approximately to give equal amounts of ferrite and austenite in solution-annealed condition. The higher the annealing temperature, the higher the ferrite content in the steel. Although Duplex steels are prone to precipitation to nitrides and carbides type of acids that cause embrittlement and decreased corrosion resistance. If the temperature is about 4750C, probably you can say in the range of 3000-5000C it can cause embrittlement and also the decomposition of ferrite content. Duplex do have excellent ductility and toughness but they cannot reach the superior values of pure austenitic grades.

1. It offers greater strength and higher resistance to stress-corrosion cracking than most other types of stainless steel.
2. They have significantly better ductility and toughness than other ferritic grades.
3. Due to their lower alloying content, it is very less costly.
4. Duplex steels have a wide range of corrosion resistance depending upon the content of ferrite and austenite elements.
5. It has high mechanical strength.
6. Good weldability
7. Very high energy absorption
8. Low thermal expansion.

Typical Applications of Duplex Flanges Include :

• It is primarily used to join two pipes using bolts which are an integral part of the structure of a building or sky-scraper.
• Combine sea-water piping systems.
• They are extensively used in storage tanks, pressure vessels to keep them intact and heat exchangers.
• Nuclear and solar power industries.
• Geothermal, pharmaceutical and petrochemical utilization.
• LNG (Liquefied Natural Gas) pipes.
• Biomass and mining industries.
