Hot-Dip Galvanized Rectangular Elliptical Finned Tube for Heat Exchanger

Hot-Dip Galvanized Rectangular Elliptical Finned Tubes feature punched rectangular fins attached to an elliptical core tube. Hot-dip galvanizing creates a tight metallic bond between the core tube and the fins, making them difficult to remove and offering excellent corrosion resistance.

Manufactured using an automated high-speed punching machine and a stringing process, the fins maintain a stable pitch. The finned tubes are hot-dip galvanized throughout, creating a uniform zinc coating with a thickness of at least 0.06mm. This creates a secure bond between the tube and fins, resulting in efficient heat transfer and minimal air resistance. Compared to round tubes of the same cross-section, the heat transfer coefficient can be increased by approximately 25% and air resistance can be reduced by approximately 15-25%.

Elliptical string finned tubes are a type of heat exchanger tube bundle commonly used in various industrial applications and heating or cooling systems. Their design provides efficient heat transfer and a large heat transfer surface area, making them suitable for applications requiring high heat exchange.

This tube bundle structure consists of multiple elliptical segments arranged and interconnected to form a densely packed bundle. Each segment features a series of fan-shaped fins, which increase the surface area of the segment and enhance heat transfer. The elliptical design helps reduce the size of the tube bundle and improves fluid flow efficiency within the bundle.

Elliptical finned tubes are typically made of metal materials such as stainless steel, aluminum alloy, or copper to meet corrosion resistance requirements in various operating conditions. This tube bundle structure is widely used in the chemical, petroleum, pharmaceutical, and food processing industries for heating, Kühlung, evaporation, and condensation processes.
