What is copper finned tube?

A copper finned tube is a type of heat exchanger tube that has fins on its outer surface made of copper or copper alloy tube. The tube consists of a base tube made of a different copper or copper alloy material, such as copper C12200, Brass C44300 or copper nickel tube, and a series of copper fins that are attached to its outer surface. Copper is an excellent material for fins because of its high thermal conductivity and corrosion resistance.

Copper finned tubes are commonly used in various industrial applications where high heat transfer rates are required. They are particularly useful in applications where the fluid being heated or cooled has a high fouling potential, such as in the petrochemical and chemical industries. The fins on the tubes surface create turbulence in the fluid flow, which helps to prevent fouling and improve heat transfer efficiency.

Copper finned tubes are also used in air-cooled heat exchangers, where they are typically used with high-performance fans to achieve high heat transfer rates. Copper fins have a higher heat transfer coefficient than other materials, which means they can transfer heat more efficiently.

One of the advantages of copper finned tubes is their resistance to corrosion. Copper is a highly corrosion-resistant material, which makes copper finned tubes ideal for applications where the fluid being heated or cooled is corrosive. Copper finned tubes also have a long service life, which reduces maintenance costs.

Overall, copper finned tubes are a popular choice for various industrial applications due to their high heat transfer efficiency, resistance to corrosion, and long service life.
