Super Duplex Pipe Fittings

Super Duplex Pipe Fittings are used in pipe systems to connect straight pipe or tubing sections. The main use of Super Duplex Pipe Fittings is to make the pipe or the tube adaptable to different sizes or shapes. Super Duplex Pipe Fittings Manufacturers are also used for other purposes such as regulating or measuring fluid flow. The term plumbing is generally used to describe conveyance of water, gas, or liquid waste in ordinary domestic or commercial environments, whereas piping is often used to describe high-performance conveyance of fluids in specialized applications. The term tubing is sometimes used for lighter-weight piping, especially types that are flexible enough to be supplied in coiled form.


A microstructure of austenite and ferrite which has improved strength over ferritic and austenitic steel grades. The composition of both these microstructure is in 50:50 ratio. Superduplex has a higher molybdenum and chromium content. This gives the material greater corrosion resistance than standard duplex grades. It exhibits extreme corrosion resistance to organic acids like formic and acetic acid. This is due to the high molybdenum and chromium content. Super Duplex are also known for providing excellent resistance to inorganic acids, especially those containing chlorides. It provides cost effective resistance without need to compromise on quality and performance. Supeduplex just like is counterparts has lower alloying costs when compared with similar ferritic and austenitic grades with equipment corrosion resistance in chloride containing environments due to the material’s increased tensile and yield strength. It gives purchaser the option of purchasing smaller thickness without the need to compromise on quality and performance. It has high intergranular and pitting corrosion resistance due to its high composition of chromium, nickel and molybdenum. Addition of nitrogen improves structural hardening. This is done by interstitial solid solution mechanism which results in high yield strength and ultimate strength values without impairing toughness. Super duplex stainless steel in addition of having high strength, it also provides good sulfide stress corrosion resistance. Compared to austenitic steels it has low thermal expansion and higher heat conductivity. It provides excellent resistance to chloride stress- corrosion cracking.

Special Properties

  • Excellent resistance to stress corrosion cracking in chloride containing environments
  • Listed in NACE MR 01 75 for sour service
  • Tested to the highest degree using tests designed to guarantee that the trade-marked product possesses high integrity, a correct phase balance and the absence of sigma and other deleterious phases
  • ASME approval for pressure vessel application
  • Particularly applicable for large forging as the formation of sigma phase is less likely that it is for other superduplexes

Typical Applications of Super Duplex Pipe Fittings Include :

  • Oil and gas industry applications.
  • Pollution control.
  • Pulp and paper production.
  • Desalination process.
  • Mining and mineral industries.
  • Marine industries.
  • Power generation.
  • Flue-gas desulfurization.
  • Chemical, pharmaceutical.

Super Duplex Stainless steel is one of the most diverse alloy family. Its pricing depends on the type of alloy our customer selects. It is usually cheaper compared to other alloys which usually have high chromium content and other expensive metals to enhance their properties. We make Super Duplex Pipe Fittings according to the specification given by our client. Price of Super Duplex Pipe Fittings Suppliers will vary depending upon the specifications and mechanical properties.

The Processing of steel carp and alloy together leads to the production of Inconel Steel. The amount of Alloy mixed decides the capability of the Steel works.

But still they are following steps:

1. Step one is to melt the metal including alloy and non-alloy into an electric arc furnace and later on adding the chemical energy like carbon, ferrosilicon, oxygen or fuel gas mixtures to speed up the process

2. After the melting process is done. The melts still is further processed in AOD which is Argon-Oxygen Decarburization. In which the carbon content is reduced and the mixture of Argon and Oxygen is added.

3. If we need low amount of Argon and oxygen then melted steel is added to the VOD which is Vacuum Oxygen Decarburization. And then melted steel is poured on the ladle
