A high-frequency resistance welded finned tube, also known as a high-frequency welded finned tube or spiral steel solid finned tube, is an efficient heat exchange element formed by welding fins to a base tube using high-frequency current. Its core advantages include high welding strength, low thermal resistance, and a large […]

Wrapped Finned Tubes, also known as Wrap Around Fin Tubes, are high-efficiency heat exchange elements that fix fins to the outer surface of a base tube through a mechanical wrapping process. Their core advantages lie in high heat transfer efficiency and structural stability. I. Technical Characteristics of Wrapped Finned Tubes

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.
