Overlapped L Type Fin Tube - China

LL-Foot Fin Tube - Overlapped L-type fin tubes commonly known as double L or overlapped L fin, are used in applications where temperatures do not exceed about 350 degrees Fahrenheit The fins are manufactured from the strip is similar to the L type except that the foot is preformed into an accurately controlled stepped double L shape, rolled into a taper which causes it to curl.

LL-Foot Fin - Overlapped L is then continuously helically wound under tension onto a tube.

The fin hugs the tube with one fin overlapping the foot of the next fin with complete coverage of the base tube.

This gives good corrosion protection to the tube.

This type of tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.

The fins are similarly secured at each end as the L fin.

The Fin foot is pre-formed into an LL shape (overlapped LL) and applied to the base tube under tension.

However, the foot is pre-shaped to give overlap of one foot onto another, thereby improving base tube protection and thermal contact area - Fin materials: Aluminum - Base tube materials: Any metallic material.

The smooth flat fins perpendicular to the tube surface give rise to very low resistance to air/gas flow and ensure that fouling is kept to a minimum.

The foot of the fin is in contact with the base tube and provides a complete sheathing over the finned length.

The Overlapped "L" fin design has interlocking fins that are wound together to prevent movement and separation.

The fin protects the entire tube, so the designation works well for applications where corrosion is a factor.

This type of finned tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.

• 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.
