Definition

A studded fin tube, also known as a studded tube or pin fin tube, is a type of finned tube used in heat exchangers to enhance heat transfer efficiency. Especially in the convection chamber of the tubular furnace, in order to enhance the heat transfer effect outside the tube, the heat transfer element often adopts the studded tube. Studded fin tubes significantly increase the surface area for heat transfer compared to plain tubes. This increased surface area allows for more efficient heat exchange between the fluid inside the tube and the surrounding environment. The heat transfer efficiency of studded fin tubes can be 2-3 times higher than that of bare tubes.

Studded fin tubes are made by welding specially formed studs (round pins) onto the surface of a base tube. These studs can be arranged in rows around the tube and can vary in size and shape to meet specific requirements.

Typically constructed from materials such as carbon steel, stainless steel, alloy or copper, providing durability and resistance to corrosion.The choice of material depends on the application and the specific requirements for corrosion resistance, thermal conductivity, and mechanical strength.

Advantages

The main advantages of studded fin tubes include their high heat transfer efficiency, durability, and versatility. They can be customized to fit different sizes and configurations, making them suitable for a wide range of industrial applications.

Application

Studded fin tubes are used in a variety of heat exchanger applications, including boilers, heaters, and other industrial processes where efficient heat transfer is required. They are particularly useful in applications where the airside heat transfer coefficient is low, as the studs provide additional surface area and promote turbulence, which enhances heat transfer.

In summary, studded fin tubes are a specialized type of finned tube designed to enhance heat transfer efficiency in heat exchangers. They achieve this by increasing the surface area for heat exchange and promoting turbulence, making them highly effective in various industrial applications.
