Extruded Serrated Finned Tube - China

A smooth core tube is inserted into an aluminium tube and then fins are extruded out of the aluminium tube.

Advantages: Bond to outer and inner tube removes the risk of loss of contact due to thermal stress, fins are more rigid, and the Core tube is extensively protected against corrosion by the aluminium sleeve.

As per type HY, but fins are serrated.

Advantages: Higher heat transfer coefficient, for same pressure drop compared with HY fin.

Material Combinations:

- Core Tube: Carbon steels, low-alloy steels, stainless steels, brass, copper, copper-nickel alloys, aluminium bronze, nickel-alloys, as well as exotic grades.

Core tubes with extremely thin wall materials can be applied.

- HYS Fin Tube Exterior Tube & Fins: Generally Aluminium (different grades available) Fields of Application:

- Petroleum, chemical and petrochemical industries

- Natural gas treatment

- Steel industry: blast furnace and converter cooling systems

- Power generation: steam turbine exhaust condensing (contact condensing with cooling of circulating condensate)

– Fossil and nuclear power plants

- Air conditioning (freon, ammonia, propane)

- Incineration of household refuse

- Compressor coolers, etc.

Manufacturing Process:

A polished and deoiled base tube is set in an aluminium sleeve.

The whole goes through the fin machine which consists of three spindles set at 120° each bearing a stack of plates.

These plates, stacked in form and diameter first build the fin, then bonds the outer and inner tubes together.

In certain cases (high airspeed) the fins are serrated after the finning process so as to increase the heat transfer coefficient.

Advantages:

1) Thermal

The bonding of the outer and inner tubes removes the risk of loss of contact with the aluminium due to thermal stress.

Maximum operating temperature: 250° C.

The transfer coefficient remains steady.

Additionally, as the outer sleeve is continuous no electrolytic couple is created.

2) Mechanical

The fins are more rigid and stand the handling shocks better, compared to types "G" and "L".

• 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.
  
  Specific types such as Embedded Fin Tube also called G Type Fin Tube, L Fin Tube, LL Finned Tube, KL Finned Type also call knurled Finned Tube, Extruded Fin Tubes, Extruded Serrated Fin Tube, Square Fin Pipe also call H Fin Tube, Rectangular Fin Pipes also called Double H Fin Tube, Longitudinal Finned Tubes, Studded Tube and Nailhead Pipe, High-Frequency Welded Serrated Fin Tube, High-Frequency Welded Solid Fin Tube.
  
  T.S. Industrial privately owned company and finned tube manufacturer.
  
  We are not owned by, nor do we own, any steel producers.
  
  Our independence from steel producers ensures that we are objective in matching exact customer needs in terms of quality, specifications, and delivery.
  
  T.
  
  S Industrial provides finned pipes products and services to the power plants, petrochemical industries, boiler & heat exchangers, nuclear stations, paper, shipbuilding sectors as well as refrigerating industries.
  
  Incorporated with manufacturers and fabricators in China, we can supply in accordance with most international standards with high-qualified and cost-effective products.
  
  Our main strength lies in the heat exchanger tubular, especially finned tubes, which can be long up to twenty meters, and usually delivered in U-bent form.
