L Foot Tension Wound Finned Tubes - China

L-Type Tension Wound Finned Tubes also called Wrap-On Finned Tubes, which used in applications where temperatures are lower than 300℃.

In other words, L-fin tubes are mainly used in low-temperature applications where some degree of tube wall protection is needed.

L-Foot tension wound fin tubes consist of two parts, aluminum fin, and base tube.

The thin aluminum fin strips are tightly wound helically around the base tube circumference.

A foot is first formed at one side of the fin strip (Called the name L foot).

The strip is then wound tightly around the tube, with the foot bearing on the tube's outer surface.

These short horizontal limbs of each L are in full contact with the base-tube surface to cover it completely.

While Tension in the fin strip as it is wrapped around the tubes serves to seat the fin foot forcefully on the tube, and then to hold the fin firmly in place.

L-footed finned tubing offers maximum heat transfer at lower temperatures and circumferences.

The unique L-shaped design holds fins rigidly to withstand heat cycling and high-velocity air vibration.

These fins offer a certain degree of atmospheric protection of the tube wall anti-corrosion.

The broad contact surface between the tube and the fining enhances heat transfer.

This fin design is highly efficient and cost-effective.

The ends of the fins have to be stapled to prohibit the aluminum fin from unraveling or losing contact between the fin foot and the base tube.

This contact is critical to the operation of the air coolers since the heat is transferred from the tube wall, through the fin, to the surrounding hot air.

L Finned tubes Advantages:

- Suitable for use in the low-temperature application

- This kind of fining type is the most cost-effective way compared to the others.

- The failed fins could easily be removed during production and bare tubes can be used again for fining.

- There is no need to make a helical grove over the core tube.

- It is possible to place the fins on a super thin-walled tube with is particularly desirable when using expensive alloys as core tubes.

- The tubes can withstand a temperature of up to 130℃ without the risk of atmospheric corrosion or thermal stress.

L Finned Tubes Weakness:

The fins are not so strong to resist mechanical damage when external forces applied to the fin area

Handling shall be carefully done with care to avoid any damage.

Finned tubes may be damaged when using either steam or high-pressure water for cleaning

As the fins are helically wrapped in grooves, the un-finned area is not covered which can be exposed to corrosive media, and galvanic corrosion at the base of the fins can be accrued

Tubes shall be very straight with a smooth outside area to make good finned tubes

Fins should be fixed at both ends to avoid un-wrapping L Finned Tubes Application:

• 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.
