Duplex Heat Exchanger Tube and Duplex 2205 Boiler Tube supplier in India

DSS is a two-phase microstructure of ferritic and austenitic grade. A Duplex Tube is designed with a superior chemical composition of nickel, chromium, and molybdenum. This content gives the tubes superior resistance to corrosive and reducing media across stress-induced environments. The Duplex Tubing possesses superior strength and has a higher fatigue resistance. These tubes have good working temperatures and have a larger thermal conductivity. Duplex 2205 tube has a minimum tensile strength of 90ksi with a minimum yield strength of 65ksi. They have a hardness of 32 max hardness RC and can be elongated by 25%. The S32205 Tube has a higher resistance to pitting and corrosive media compared to the S31803 tube. These tubes have a higher content of nitrogen in their composition, giving them better protection against harsh conditions. An S31803 Tube has a density of 7800 kg/m3 and showcases excellent weldability.

A Duplex Welded tube is produced as metal sheets or strips are rolled and subsequently welded to form the tube. These tubes are preferred in moderate to low pressure and temperature applications. The Duplex Seamless Tube, on the contrary, is designed without any welds or seams. Produced via the extrusion process, these pipes have 20% superior strength in comparison to welded tubes. These tubes are preferred in treacherous applications across different systems. Duplex Boiler Tube is a pressurized vessel grade that can withstand high as well as low pressures and temperatures. These tubes can withhold and process toxic fluid and media across vigorous conditions. The Duplex Heat exchanger tube is a versatile grade that is employed in transferring heat from two or more fluids. These tubes can be used for mixing hot and cold fluids and have good internal reliability. Duplex Coiled Tubing is a small-diameter continuous pipe that is used in drilling in oilfield technology and remediation techniques. We are leading Duplex Tube suppliers in India

Advantages of DSS 2205 Welded Tube

  • Toughness and ductility: It is tougher and more ductile than ferrite grades. They fall short of the best austenitic grades.
  • Corrosion resistance: Alloy 2205 Tubes are exceptionally corrosion resistant, and they display very high resistance to stress corrosion cracking even in chloride and sulphide conditions (SCC). SCC is a form of corrosion that occurs when three conditions are met: tensile tension, a corrosive environment, and a sufficiently high temperature.
  • Cost: It is less expensive because it contains less nickel and molybdenum than its austenitic counterparts with similar corrosion resistance.
  • Strength: DSS Tubes are roughly twice as strong as conventional austenitic or ferritic stainless steels.
  • Heat Resistance: Alloy 2205 Tubing is more heat conductive and has less thermal expansion than austenitic steels. DSS grades are easily employed down to temperatures of at least -50°C because they have more ductility at low temperatures than ferritic grades of steel.

Technical parameters of DSS U-bent heat exchanger tubes

  • Outside Diameter: 12.7- 38 mm
  • Bending radii: 1.5 x OD up to 1,250 mm.
  • Minimum bending radii: OD over 28 mm after agreement.
  • Leg length: 1,000 mm to 12,000 mm.
  • Heat treatment for radii: up to 1,000 mm

Technical parameters of DSS U-bent heat exchanger tubes

  • High resistance to corrosion
  • Suitable for usage in extreme situations, such as seawater, and has a long service life.
  • DSSPipe with twice the strength of austenitic stainless steels
  • Visual Inspection ReportsStress corrosion cracking resistance has been improved.
  • Thermal expansion is minimal.
  • Weldability is excellent.
  • Long lifespan and high cost-effectiveness
  • Excellent mechanical properties
  • Excellent resistance to intergranular corrosion

Technical parameters of DSS U-bent heat exchanger tubes

Each tube must pass a nondestructive electric test or a hydrostatic test. Unless otherwise indicated in the purchase order, the type of test to be employed is at the discretion of the manufacturer.

The hydrostatic test shall be performed in accordance with Specification A1016/A1016M, with the exception that in calculating the hydrostatic test pressure, 64000(441.2) shall be replaced for 32000. (220.6).
