Low Finned Tube ASTM A268 TP439 EN10217-7 1.4510 for Air Cooler
YUHONG'S low-heat dissipating fin tube is a steel tube that has fins formed on the outside by a roll forming process. Typically, there are 19 fins per 25.4mm (1 inch) of length, but our company can manufacture tubes with 26 fins per length. The outer surface area of the tube is more than 3.5 times the inner surface area, which results in superior heat transfer performance compared to generally circular profile steel tubes. By enhancing the heat transfer performance, it is possible to achieve downsizing of various machines (reducing capacity and weight) and improve material costs, transportation costs, and installation space.
YUHONG have extensive practical experience in various heat exchangers used in petroleum refining plants, petrochemical plants, gas turbine power generation, refrigeration units, and other applications.
Depending on the specific usage, YUHONG'S products include those that increase the outer surface area of the tube and high-heat dissipating fin tube products that have fins welded to the outer circumference of the steel tube. The low-heat dissipating fin tube is directly roll-formed onto the steel tube, so there is no need to worry about delamination even when subjected to bending. Furthermore, it retains excellent durability and resistance to vibration even after initial operation.
In addition, YUHONG is able to collaborate with partner factories to produce high-heat dissipating fin tubes. For details, please contact our company. We can also process fins in aluminum and stainless steel. By combining our cold-drawn steel tubes with high-heat dissipating fin processing, we strive to meet your demands for material, delivery time, and quantity as much as possible.
Applications of YUHONG low fin tubes:
Heat Exchangers: Low fin tubes are commonly used in the manufacturing of air-cooled heat exchangers for applications such as HVAC systems, chemical processing, and refrigeration units.
Process Heat Transfer: Industries such as petrochemical, oil and gas, and power generation often utilize low fin tubes in heat exchangers and condensers to improve thermal performance and increase energy efficiency.
Refrigeration and Air Conditioning: Low fin tubes are employed in the production of evaporators and condensers for commercial and industrial refrigeration systems, as well as in air conditioning units.
Power Plants: Low fin tubes find application in power plants for the condensers, feedwater heaters, and other heat exchange equipment to improve overall efficiency of power generation processes.
Chemical Processing: Low fin tubes are used in various chemical processing applications, including in reactors, heaters, and coolers, where efficient heat transfer is crucial for production processes.
