3. Processing Technology
The production of KL-Type wound finned tubes adopts advanced winding technology. First, the ASME SA179 base tube is subjected to strict surface treatment to remove impurities and ensure good contact with the fins. Then, the aluminum fins are tightly wound around the base tube through a professional winding machine. During the winding process, precise control of the winding tension and pitch is carried out to ensure that the fins are firmly attached to the base tube, reducing contact thermal resistance. Finally, the finished product undergoes strict quality inspection, including dimensional inspection and fin bonding strength testing, to ensure that it meets the ASME SA179 standard.
4. Performance
Heat Transfer Performance: The combination of aluminum fins with high thermal conductivity and the winding process makes the heat transfer efficiency of the product significantly improved. Compared with ordinary finned tubes, it can increase the heat exchange rate by 20-30% in air cooler heat exchangers.
Structural Stability: The tight winding of the fins ensures that the product has good structural stability, can withstand the vibration and pressure during operation, and is not easy to loose or fall off.
5. Application Scenarios
KL-Type wound finned tubes are widely used in air cooler heat exchangers in various industries:
Petrochemical industry: Cooling of various process fluids, such as crude oil, natural gas, etc.
Power industry: Cooling systems in thermal power plants, such as turbine oil cooling.
Refrigeration industry: Condensers and evaporators in refrigeration equipment.
6. Product Advantages
High Heat Transfer Efficiency: The excellent thermal conductivity of aluminum fins and the tight winding structure greatly improve the heat transfer effect.
Good Structural Stability: The winding process ensures the firm combination of fins and base tube, which is not easy to loose and has a long service life.
