Duplex Pipes

Om Tubes and Fittings Industries is one of the leading and foremost brands in the Duplex Pipes. We are the best suppliers of duplex pipes over a past decade and our product delivery is the fastest in the world. We are the most highly experienced and proficient makers of nickel-based alloy. Om tubes mainly specializes in the various nickel, stainless, duplex and super alloys in the form of plate, sheet, bar, tubing, pipe, flanges, fittings, wire and welding material. We serve customers of various countries with all size demands. We supply, process and custom fabricate product for various industries including chemical processing, mining, oil and gas, power generation, petrochemical and more. Great emphasis is paid to value addition and after sales service. The main goal of this organization is to provide commodities of unparalleled quality, in addition with making our client’s buying experience world-class and a memorable one.
Today, our industry is filled with high volume but low quality suppliers which are below the mark with what the steel industry needs. Because of such circumstances, it results in the decline of the quality of goods and hence, the entire project. But today, our firm are one of the proficient organizations in the steel industry. All our hard work and commitment are directed towards our clients an excellent purchase cycle. That makes us unique from the rest. We boast of having distributing our products in more than 13 countries in the world, especially to several European, African and Gulf based companies, for over a decade. Consequently, our clients gives our company as a recommendation to other prospectors which itself is enough to prove our transcendence in the steel industry.

duplex pipes

A Duplex Pipes is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.
In common usage the words pipe and tube are usually interchangeable, but in industry and engineering, the terms are uniquely defined. Depending on the applicable standard to which it is manufactured, pipe is generally specified by a nominal diameter with a constant outside diameter (OD) and a schedule that defines the thickness. Duplex Pipes is most often specified by the OD and wall thickness, but may be specified by any two of OD, inside diameter (ID), and wall thickness. Pipe is generally manufactured to one of several international and national industrial standards. While similar standards exist for specific industry application tubing, tube is often made to custom sizes and a broader range of diameters and tolerances. Many industrial and government standards exist for the production of Duplex Pipes and tubing.

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.

  • It offers greater strength and higher resistance to stress-corrosion cracking than most other types of stainless steel.
  • They have significantly better ductility and toughness than other ferritic grades.
  • Due to their lower alloying content, it is very less costly.
  • Duplex steels have a wide range of corrosion resistance depending upon the content of ferrite and austenite elements.
  • It has high mechanical strength.
  • Good weldability
  • Very high energy absorption
  • Low thermal expansion.
  • Oil and gas equipment.
  • Offshore technology.
  • Seawater desalination plants.
  • Chemical industry, especially when handling chlorides.
  • Flue-gas cleaning.
  • Desalination plants and seawater systems.
  • Pulp and paper industry.
  • Cargo tanks and pipe systems in chemical tankers.
  • Firewalls and blast walls on offshore platforms.
  • Bridges.
  • Storage tanks.
  • Pressure vessels, reactor tanks, and heat exchangers.
  • Rotors, impellers, and shafts.
