Serrated finned tubes consist of a base tube with serrated fins attached to its outer surface. The presence of these fins helps to increase the rate of heat transfer between the fluid inside the tubes and the air or gas flowing over the fins.And serrated fins increase the heat transfer surface area for more efficient heat exchange. These fin tubes are usually made of materials such as carbon steel, stainless steel or copper. They are used in various industries including power generation, petrochemical and HVAC systems.Overall, serrated finned tubes are designed to improve heat transfer performance.

Features Of Finned Tube
1. The design of serrated fins can increase the effective surface area for heat transfer, improve heat transfer rate and overall efficiency.
2. Reduce air-side pressure drop: The serrations on the fin surface help break up the boundary layer and reduce air-side pressure drop, thereby reducing energy consumption and operating costs.
3. Improved anti-fouling ability: The serrated fin design also helps to minimize fouling and improve the performance and service life of the heat exchanger.
4. Versatility: Serrated finned tubes can be used in a variety of applications and industries
5. Customizable options: serrated finned tubes can be customized to meet specific requirements
