The Serrated Helical Fin Tube is a superior heat transfer tube which has been designed by using the method of welding the serrated metal fin around the tube with the application of high-frequency welding. The use of these tubes is widely spread in heat exchangers, boilers, economizer, air cooler, waste heat recovery units and HRSG systems due to increased thermal performance (compared to normal fin tube) attributed to enhancement of turbulent fluid flow, reduced fouling and increased heat transfer.
Introduction to Serrated Helical Fin Tube
A Serrated Helical Fin Tube is designed for greater efficiency, developed specifically for conditions where high thermal performance is required. Unlike a standard fin tube, serrated fins are constructed with a series of regularly placed, accurately cut serrations along the outer edge of each fin. As air passes over the serrated edge, boundary layers are broken down by inducing turbulence which results in dramatically increased heat transfer values.
As an established Helical Serrated Finned Tubes Manufacturer we provide you with top-performing fin tubes capable of delivering optimal heat conductivity, strength and longevity. Welded Helical Serrated Finned Tubes are found in numerous power generation plants, oil and gas plants, petro-chemical plants, fertilizer plants, HVAC, marine industries and heat recovery systems.
With many years experience in this field and following strict international standards of quality, we provide Welded Helical Serrated Finned Tubes capable of operation under severe conditions of temperature and pressure.
What is a Serrated Helical Fin Tube?
A Serrated Helical Fin Tube consists of:
- A metallic base tube
- Continuous serrated fin strips
- High-frequency resistance welded joints
- Constant pitch helix fin helix
The fin strip is helically wound around the tube and is attached by high frequency resistance welding. The serrated edges/cuts at the edge of the fin cause several points where the air flow is disrupted. The design reduces dust build-up and increases heat transfer.
This design makes Helical Serrated Finned Tubes particularly effective in applications where fouling, dust buildup, or inefficient airflow can negatively affect thermal performance.

How Serrated Fins Improve Heat Transfer Efficiency
The primary purpose of serrated fins is to create turbulence.
Benefits of Serrated Fin Design
This is why High-efficiency heat exchanger fins with serrated geometry are increasingly preferred over conventional solid fin designs.
