Spiral finned tube is an efficient heat transfer element with spiral fins.
Spiral finned tubes have been widely used in boiler economizers, air preheaters and heat recovery of waste heat boilers, as well as heat transfer equipment in various fields such as chemical industry and pressure vessels. The capacity of the units used in boilers has also increased from small to large, and the applications are increasing. There are many professional manufacturing plants in China that can produce high-frequency welding and brazing spiral finned tubes, and finned tube production equipment and technology from the introduction, digestion, absorption to self-development design, manufacturing, quality has reached the requirements of advanced foreign standards.
The advantages of using finned tubes:
1) The effective space increases the heat transfer area and improves the heat transfer effect.
2) Reduce the space occupied by the heat transfer surface, so that its volume is reduced, especially suitable for quick installation boilers.
3) Reduce the cost of equipment and improve the safety of equipment.
4) Reduced operating costs due to lower pressure drop on the water side, etc.
5) Increased stiffness of finned tubes improves the vibration resistance of the tubes, etc.
