]]> High Frequency Finned Tubes https://www.sci-fintube.com/en/product/high-frequency-finned-tubes-en/ Sat, 01 Oct 2022 04:17:30 +0000 https://www.sci-fintube.com/?post_type=product&p=1273 The major uses for high frequency welded finned tubes are in the heat recovery associated with boilers for power generation and in furnace applications for the petrochemical industry.

The steel fin, that may be solid or serrated, is helically wound and continuously welded to the tube by high frequency electric resistance welding. This produces a homogeneous, clean and continuous fin-to-tube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion.

The use of high-frequency current results in much localized heating of the tube surface and the edge of the fin. This skin effect produces higher weld speeds, while post-weld heat treatment is not considered necessary because of the superficial nature of the changes in the microstructure.

The maximum capacity of high frequency welding machine can support the tube diameter between 25 mm and 219 mm.
Tube material: steel, alloy, stainless steel and Nickel Alloy
Fin Material: carbon Steel, stainless steel and Nickel Alloy

]]> Air Heater / Air cooler https://www.sci-fintube.com/en/product/air-heater-air-cooler-en/ Sat, 16 Jun 2018 07:04:45 +0000 http://www.sci-fintube.com/?post_type=product&p=614 The most common application of Air Heater / Air cooler is used for heating, cooling and absorb heat (Economizer) with ambient air as the cooling medium rather than water.

Advantages

  • There is little fouling or corrosion on the air side of heat exchanger
  • There is no possibility of leakage and mixing of water with the process fluid
  • Lower capital cost and operating than their water-cooled equivalent

Disadvantages

  • Low thermal conductivity, Low density and Low heat capacity
  • Fan driven air-cooled heat exchanger may be noisy
  • Larger than their water-cooled equivalent

The application of Air Heater / Air cooler is in industry, such as Steam condensers, Water coolers, Oil coolers, Air coolers, Air pre-heaters, Economizer and Product coolers: gas, chemicals, petrochemicals etc.

  • High pressure and temperature capability
    Suitable for heavy-duty industrial processes involving high operating pressure and temperature.
  • Highly customizable and flexible design
    Tube count, passes, materials, and TEMA configurations can be tailored for specific process conditions.
  • Handles dirty or viscous fluids well
    Larger flow channels make it suitable for fouling-prone or high-viscosity fluids.
  • Ease of maintenance
    Removable tube bundles allow convenient mechanical cleaning and inspection.

Disadvantages

  • Large footprint requirement
    Requires more installation space compared with compact plate heat exchangers.
  • Higher initial and fabrication cost
    Material and manufacturing cost are generally higher, especially for corrosion-resistant alloys.
  • Fouling susceptibility inside tubes
    Scale and deposit buildup over time can reduce thermal performance and require planned maintenance.

Shell and tube heat exchangers are used in various applications, such as reboilers and condensers in distillation columns, cooling water systems for machinery, heat recovery to reduce energy consumption, and chillers (shell & tube evaporators / condensers), among others.
