High-frequency welded fin tubes are an efficient heat transfer element that have wide applications in many fields. The following is a detailed description of high-frequency welded fin tubes products:

One, Product Overview

High-frequency welded fin tubes are one type of fin tubes that use high-frequency current for welding, mainly welding longitudinal or spiral seams. During the welding process, the base tube and fins are basically integrated into one, forming an efficient heat conduction channel, which makes the heat transfer efficiency higher. According to the material, high-frequency welded fin tubes can be divided into steel tube spiral fin tubes and steel tube aluminum fin tubes.

Two, Technical Features

Efficient welding: High-frequency welding technology can weld the fins and tubes together in a short time, with fast welding speed and high production efficiency.

Excellent heat transfer performance: Since the base tube and fins are tightly combined, a high-efficiency heat conduction channel is formed, resulting in a significantly improved heat transfer efficiency.

Good corrosion resistance: High-frequency welded fin tubes are usually coated with rust-resistant paint and silver powder to prevent rust, with good corrosion resistance.

Strong customizability: High-frequency welded fin tubes can be customized according to the actual needs of users. The steel pipe diameters commonly used for fin tubes are 1 inch, 1.5 inches, and 2 inches, and the length can be customized from 1 to 8 meters.
