Integral Low Finned Tube - China

Integral Low Fin tubing is a kind of single metal fin tube, which is a type of extruded tubing that consists of small low fins.

The low fin tube is very similar to the extruded "high fin" types but these tubes have the same diameter as the base tube.

Low Fin Enhanced tubes can be used in standard shell and tube baffles and tube sheets.

The primary advantage of the low fin tube is providing surface enhancement and better heat transfer over smooth tubing.

Low-finned tubes have been successfully used for controlling the temperature of gases and liquids or for evaporating and condensing refrigerants.

As mentioned before, due to their enlarged heat transfer surfaces, they provide considerable potential for savings by reducing the tube length that is needed to achieve the required performance of the unit.

Integrally finned tubes by low Finning / Integral fin tube: type low fin: Integral low fin tube for use in situations where the extended surface is required, but lack of space or heat exchanger type dictates otherwise.

Typical material, Admiralty Brass Tubing, Copper Tubing, Copper Nickel Tubing, Stainless Tubing, Carbon Alloy Tubing, Aluminum Brass Tubing stainless steel (304L, 316L, 321(H), 304H, 310, …), duplex, copper alloys, nickel alloys, Hastelloy and titanium Integral Low Fin Tube has the advantage that it can improve the thermal performance of a heat exchanger without the necessity for changing shell size, flow arrangement, or the repositioning of piping.

The external surface of the tube is increased by the formation of low fins by direct extrusion from the material of the base tube.

• Business Description: Shanghai T.S. Industrial Co., Ltd focuses on Finned Tubes, Fin Tube, and Finned Pipe used in Heat Exchangers, Boiler Economizers, Coolers, and Heaters.
  
  We supply custom fin tubes and finned pipes in various material configurations that will increase the heat exchangers' heat transfer rate and reduce operating costs.
  
  With an advanced high-frequency resistance welding finned tube production line, an annual production capacity of up to 4000 tons, the specifications of phi 22-273mm finned tube, according to national standards or customer requirements standard production.
  
  The company produces finned tubes (square fin tube, circular finned tube, spiral fin tube, H type finned tube, longitudinal fin tube, corrugated fin tube, spiral serrated fin tube, needle-shaped fin tube, plate-shaped fin tube, inner fin tube) that can be applied to the boiler, air preheater, etc.
  
  Fin tubes or called finned tubes are a major component for various heat recovery systems.
  
  The close connection between the Finning operation and the manufacturing plant allows significant savings in packaging and freight as well as working capital reduction as a result of a “just-in-time” supply chain.
  
  T.S. Industrial Supply and produce to custom requirement finned tubes.
  
  For high-frequency resistance welding finned tube.
  
  The fin, either solid or serrated, in carbon, alloy, or stainless steel is helically wound around the tube and resistance welded.
  
  For Extruded Finned Tube, the Base tube can be carbon steel, alloy Tube, and stainless steel, while the fin can be aluminum and copper alloy.
  
  Typical product, we also produce extruded serrated finned tubes.
  
  For Bending, We can be on the bare tube and also can be over the fin, is performed on-site with custom-designed duplex benders.
  
  In our typical finned tube supply range, we supply both extruded fin tubes and helical welded finned tubes, which are mainly used for the heat transfer industry.
