The High Frequency Welded Serrated Fin Tube is a high-efficiency heat transfer element widely used in various industrial and civil fields. It uses a high-frequency welding process to weld fins with a certain spacing to a base tube, forming a compact heat transfer surface. This results in advantages such as high heat transfer efficiency, low resistance, and a compact structure.

Advantages
1. High-efficiency heat transfer: The toothed structure increases the heat exchange area by 20%-35% (with a fin density of 6-12 fins/inch), while also turbulent airflow to prevent ash accumulation. For example, in waste heat recovery from gas-fired boilers, its thermal efficiency can reach over 92% (refer to ASME 2021 standard).
2. High temperature and pressure resistance: High-frequency welding provides high strength, capable of withstanding operating temperatures ≤600℃ (stainless steel) and pressures up to 10MPa, suitable for applications such as cracking furnaces in the petrochemical industry.
3. Corrosion resistance: Through galvanizing or aluminizing treatment, the service life can reach over 15 years (C5 level corrosion environment test results).
