Studded Finned Tube is a tube with a nail-shaped body, while Finned Tube is a tube with a sheet-like shape. The two types of tubes have different applications.

I. Basic Concepts of Studded Finned Tube and Finned Tube

1. What is a Studded Finned Tube?

Studded Finned Tube is a tube with a nail-shaped body. It is characterized by simple production, easy maintenance, and excellent heat dissipation. It is currently mainly used in industries such as petrochemicals, power generation, and refrigeration equipment. Its main application is in tower equipment with high-viscosity media, such as trays, tunnels, and base plates. It can be used interchangeably with tray materials.

2. What is a Finned Tube?

Finned Tube is a tube with a sheet-like shape. It features a large surface area and excellent heat dissipation. It is mainly used in air heat exchange equipment, air conditioning and refrigeration equipment, and boiler heat exchangers. The manufacturing technology of finned tubes is relatively complex and generally requires advanced automatic machine tools and equipment.

II. Structural Characteristics of Studded Finned Tube and Fin Tubes

1. Structural Characteristics of Studded Finned Tubes

The center of the tube wall of a studded finned tube is treated with a nail-shaped process. This creates a nail head between the tube diameter and the inner hole, enhancing adhesion and reducing the risk of detachment. This type of tube is simple to process and easy to use, making it a relatively practical material.

2. Structural Characteristics of Fin Tubes

During the manufacture of fin tubes, a machine tool cuts a defined ribbed groove into the tube surface. Aluminum sheets are then pressed into long strips and squeezed into each groove. This increases the tube’s surface area, enhancing heat conduction and heat transfer capabilities.

III. Applications of Studded Finned Tube and Fin Tubes

1. Applications of Studded Finned Tubes

Nail-head tubes are primarily used in the petrochemical, power, and refrigeration industries. For example, symmetrical nail heads are machined on the inner wall of air compressor cylinders to improve heat dissipation. Convex nail heads are machined on the combustion chambers of oil heaters to increase the tube’s surface area and improve heat transfer.

2. Applications of Finned Tubes

Finned tubes are primarily used in air heat exchangers, air conditioning and refrigeration equipment, and boiler heat exchangers. For example, in the machinery manufacturing industry, finned tubes are often used in radiators to increase the heat dissipation capacity of components.
