Knurled Finned Tube - China

KL Fin Tubes are also called knurled finned tubes.

This finned tube is identical to the Wrap-On fin and produced with a combination of Wrap-On and Embedded.

The fins are manufactured from a strip which is performed into an accurately controlled L shape similar to the L type, rolled into a taper which causes it to curl.

It is then continuously helically wound under tension onto the tube.

The fin wrapped around the tube.

The base tube is knurled by a rotating tool, then the foot of the fin is knurled into the knurling of the base tube providing a tight bond with increased thermal performance.

Providing the correct fin strip is used the foot of one fin butts up against the next fin and there is no gap between the fins.

This gives some corrosion protection to the tube.

The fins are secured at each end to prevent unwinding similar to L fins.

The fin is wrapped around the tube and the foot is rolled into the outer surface of the pre-knurled tube and secured at each end.

Gives good surface protection to the tube and improved heat transfer compared to the L or LL-type fin.

KL -Foot tension wound finned tubes are commonly used in applications with metal Maximum Operating Temperature- up to 320°C (608°F) Advantages of the KL Fin Tubing

Tube protected against corrosion

Medium temperature applications

Increased fin-to-tube bond

Greater thermal contact than standard L fin

Added heat transfer performance due to the knurling

Increased atmospheric corrosion protection of the core tube

Good stability

Resistant to vibrations May be used at temperatures up to 320°C (608°F) The unique combination of high thermal performance and stresses resistance with atmospheric corrosion protection

KL can favorably replace any type of finned tube.

The manufactured method is exactly as the L finned tube except that the base tubes are knurled before the application of these fin feet.

After application, the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between the fin and tube, resulting in improved heat transfer characteristics.

• 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.
