Finned tubes, as important components in petrochemical plants, power plants, and other fields, are widely used due to their high heat transfer performance. Finned tubes comply with various standards, including GB/T9948, GB/T6479, ASME SA179, ASME SA213, and many others, ensuring high product quality. A wide range of materials is available, […]

Compared to plain steel tubes, finned tubes in drying heat exchangers can more effectively promote heat transfer, shorten the drying cycle, and reduce energy consumption. Heat exchange efficiency can be increased by more than 30%, and the heat dissipation area can be increased by 3-10 times, or even 8-15 times.

The finned tubes commonly used in grain drying heat exchangers are mainly steel high-frequency welded finned tubes or steel-aluminum composite finned tubes. This spiral fin structure effectively enhances airflow turbulence, creating a turbulent flow state, thereby improving drying efficiency and reducing energy consumption. High-frequency Welded Finned Tubes High-frequency welded finned

What are serrated fins and solid fins? ‌Serrated Fins‌ are characterized by their notched or sawtooth edges, which create structural variations in two airflow directions – on the side and the top. This design enhances turbulence when high-flow air or flue gas passes through, significantly improving heat transfer efficiency compared

Elliptical finned tubes with rectangular fins are constructed by stringing fins one by one onto a tube. Since the tubes are often not round (especially welded steel pipes), gaps are inevitable between the fins and the tube wall. These gaps create thermal resistance, which is addressed by employing several tight-fitting
