What are duplex heat exchanger tubes ?

Duplex heat exchanger tubes typically refer to a specific type of heat exchanger tubing produced from DSS materials. These DSS tubes exhibit good thermal conductivity which is important for efficient heat transfer in heat exchanger applications.

DSS is a material that contains a balanced microstructure of austenite and ferrite phases. This gives the duplex steel u tubes improved mechanical and corrosion-resistant properties compared to traditional stainless steel.

What sizes of duplex DSS boiler tube are available?

The DSS boiler tube is available in various outer diameter sizes. This outer diameter of the boiler tube commonly ranges from 6 mm or 0.24 inches to 60 mm or 2.36 inches or more.

The wall thickness of the DSS boiler tubes is available in the market from 0.5 mm to 0.39 inches or more. And when it comes to length, manufacturers produce these boiler tubes in lengths of 6 meters or 20 feet, 12 meters or 40 feet, or can be built to custom.

UNS S31803 u shaped heat exchanger tubing and duplex heat transfer bundles can be made to any size to suit a variety of needs.

what are unique properties of duplex Condenser Tubes?

DSS heat exchanger tubing offers good weldability which is preferable for installation and fabrication purposes. Duplex heat transfer bundles have a smooth surface that resists fouling which is the accumulation of unwanted deposits or contaminants on the tube surface.

what is the advantages and cost of Duplex steel reheater tubes compared to other materials?

  • DSS heat exchanger tubes manufacturers in India offers tube in a range of size and applications.
  • DSS reheater tubes provide efficient heat transfer due to their good thermal conductivity.
  • While the initial cost of DSS may be higher than some other materials but it offers long-term cost benefits
  • DSS exhibits excellent thermal fatigue resistance, allowing the reheater tubes to endure repeated heating and cooling cycles.

What is the maximum temperature that Duplex steel u tubes can withstand?

DIN 1.4462 evaporator tubes typically have good high-temperature oxidation resistance and can be used at elevated temperatures. Duplex steel tubes can usually sturdily bear temperatures up to approximately 300 to 350 degrees Celsius.

At these temperatures, the SAF 2205 u-shaped heat exchanger tubing retains its strength, corrosion resistance, and other desirable properties. But exposing the heat tubes to heat for a long time can lead to irreparable material damage.
