ASME SA179 Carbon Steel G Type Embedded Finned Tube With Aluminium Fin For Air Cooler
Finned tube is a device used for heat transfer, consisting of a metal tube and one or more spiral shaped metal fins. This type of finned tube can increase the surface area of the tube, improve heat transfer efficiency, and is widely used in various industrial fields, such as chemical engineering, petroleum and natural gas, power generation, air conditioning, etc.
The fins of finned tubes are usually made of materials such as aluminum, copper, stainless steel, carbon steel, etc. The shape of fins can be in various forms such as straight strip, V-shaped, W-shaped, U-shaped, etc. These different fin forms can be designed according to specific application scenarios to achieve better heat transfer effects.
The manufacturing process of finned tubes generally includes the following steps:
Making fins: Cut metal plates into corresponding shaped fins, and then shape them through processes such as pressing, stretching, and rolling.
Making pipes: Bend metal plates into the shape of pipes, and then weld or buckle the pipe ends into a complete pipe.
Installation of fins: Insert the prepared fins onto the pipe and fix them on the surface of the pipe through pressing, welding, and other methods.
Different manufacturing processes of finned tubes can affect their heat transfer efficiency, surface smoothness, corrosion resistance, and other properties. Therefore, when selecting finned tubes, it is necessary to determine the appropriate process and materials based on specific application scenarios. Common application scenarios for finned tubes include heat exchangers, air coolers, automotive radiators, etc. in petrochemical equipment.
