YUHONG GROUP L-Shaped Finned Tube

The tension dimension in the fin bar of the L-type finned tube wraps around the tube, causing the fin feet to press down hard on the tube, holding the fins firmly in place.
L-finned tubes are commonly used in air coolers in petrochemical, electric power, paper making, tobacco, building heating and other industries, as well as heat exchangers in power plants (electric power, nuclear power, thermal and geothermal power plants), where the maximum operating temperature can reach 230°C. The L-finned tubes are also used in the heat exchangers of power plants (electric power, nuclear power, thermal and geothermal power plants).

Characteristics of L-type finned tube：

Heat exchanger with L-type finned tube pressed up to form a trapezoidal cross-section and the density of heat flow distribution, tube
Combination of tight, high thermal efficiency, eliminating the contact heat and finned tubes generated by the tube. Resistance
The resistance is small, and the fins have uniform distance. Good heat transfer performance.
The tube can withstand temperatures up to 150℃. And there is no risk of atmospheric corrosion or thermal stress.
Risk of atmospheric corrosion or thermal stress.
L-Type finned tubes provide contact area between the fin bar and the tube surface to protect the tube wall from atmospheric corrosion.
The L design is much more economical than the LL, KL or even G recessed types.

Applications of L-shaped finned tubes：
1. Heat exchanger devices in power plants (electric, nuclear, thermal and geothermal power plants)
2.Air cooler in petrochemical, electric power, paper making, tobacco, building heating industries, etc.
3. Air heaters for drying systems in the food industry
4. Highly corrosive systems (desalination, fertiliser, urea systems, ammonia, gases, corrosive acids)

Advantages：
Finned tubes increase the external surface area. By installing finned tubes, the overall heat transfer rate can be increased.
This reduces the total number of tubes required for a given application, which in turn reduces the overall equipment size and reduces the project cost in the long run. In many applications, one finned tube replaces six or more bare tubes at less than 1/3 the cost and 1/4 the size.
