What is Duplex 2205?

Duplex 2205 is one of the premium grades of austenitic stainless steel. It is fabricated and used in regions which are corrosive in nature. A major use is in desalination plants and heat exchangers. The resistance to corrosion prolongs the life of the project. Moreover, the excellent yield properties render great structural strength which makes it survive and thrives under high pressure.

Duplex 2205 is a stainless steel alloy that is highly useful in corrosive environments. It consists of nickel, chromium, molybdenum and nitrogen in various proportions. These elements offer great resistance to the alloy against chloride pitting and crevice corrosion. It provides great strength and is generally used temperatures up to 600° F. It shows high resistance to chloride stress corrosion cracking and superior sulphide stress corrosion resistance. The alloy has good weld ability and offers easy workability.

Duplex 2205 is a cost-effective solution for many applications where other stainless steel alloys are susceptible to chloride stress corrosion cracking. Due to its excellent resistance properties, Duplex 2205 is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. It is also used in making chemical process vessels, piping and heat exchangers, pulp mill digesters, oil field piping and heat exchangers, flue gas desulfurization equipments and in effluent scrubbing systems.

Should you buy Duplex 2205 Pipes?

Well, it depends on. Duplex 2205 is a highly specialized and regulated grade of stainless steel. It is used by experts as a cheaper alternate for corrosive environments. However, if the environment demands a grade more superior like SS904L or high nickel based alloys, duplex 2205 must not be used. This is because it will lower the life of the project and the estimated loss due to shut down will be much more than the additional cost to buy a superior grade. It is majorly used in desalination plants, which contain a highly salty environment. Other major uses are in marine applications and boiler heat exchangers.

Case Study:

At KSC, we aim to provide our clients with a great study experience from our supplied projects. We have several requirements of Duplex 2205 Pipes each week from Africa, Europe, and the Middle East. These pipes are used in various industries such as

  • Oil and Gas Exploration
  • Process Equipments
  • Desalination Plants and Projects
  • Marine Environments
  • High Chlorine Regions
  • Liquor Tanks

These requirements are regular due to compulsion use of Duplex 2205 Pipes. We got one of the requirements from the Hub of Trading – Dubai in UAE. The problem of dealing with UAE is it gets very competitive. The same inquiry was floated to several Korean, Gulf & European Suppliers. We got the same inquiry from about 5 other companies in different countries. However the advantage was the size was nonstandard, and noncompany in the world would stock this size. Duplex 2205 is not the running item and probably dead inventory for nonstandard size, due to slow and specialized consumption. We quoted to all the companies within 30 minutes. The next day, we got to know there is another mill in Europe which had it in stock, but the prices were 80% higher than ours. We instantly furnished the sample test reports to the end user for approval. On approval, we got the order and supplied the entire quantity by Air. Needless to say, we still get several opportunities for the supply of fittings and pipes, but we instantly get the order for Duplex 2205 Pipes. We are the final destination and the end of the search for customer requirements of Duplex 2205 Pipes.
