What are fin tubes?
Fin tubes are a type of heat exchanger that is used in many different industries. These tubes have a finned surface, which increases their surface area and allows them to transfer heat more efficiently. This makes them ideal for applications where high heat transfer rates are required, such as in power plants and refrigeration systems.
Fin tubes are made from a variety of materials, including copper, aluminum, and stainless steel. They are available in a range of sizes and shapes and can be customized to meet the specific needs of each application.
One of the key benefits of fin tubes is their ability to operate efficiently at high temperatures and pressures. This makes them suitable for use in a wide range of applications, including air conditioning, heat exchangers, and radiators.
In addition to their high thermal performance, fin tubes are also durable and long-lasting. They are resistant to corrosion and can withstand the harsh environments often found in industrial settings. This makes them a cost-effective solution for many different industries.

Short Description
G Type Embedded Finned Tube is that the fin strip is tension wound and placed in the groove cut into the tube with appr, 0.4mm groove depth, then the bottom of the fin is guided into the groove and backfilled with base tube Firmly.
G Type Embedded Finned Tube
G Type Embedded Finned Tube is that the fin strip is tension wound and placed in the groove cut into the tube with appr, 0.4mm groove depth, then the bottom of the fin is guided into the groove and backfilled with base tube Firmly, finally lock the fins in place by rolling the grooves enclosed in the bottom of the fins. The maximum operating temperature of G Type Embedded Finned Tube can reach 400°C.

Advantages
Transferring heat from a hot fluid into a colder fluid through a tube wall is the reason many of us use finned tubes.
But you may ask, what is the major advantage of using a finned tube? Why can’t you just use a regular tube to make this transfer? Well you can but the rate will be much slower.
By not using a finned tube the outside surface area is not significantly greater than the inside surface area. Because of that, the fluid with the lowest heat transfer coefficient will dictate the overall heat transfer rate. When the heat transfer coefficient of the fluid inside the tube is several times larger than that of the fluid outside the tube the overall heat transfer rate can be greatly improved by increasing the outside surface area of the tube.
Finned tubes increase outside the surface area. By having a finned tube in place, it increases the overall heat transfer rate. This then decreases the total number of tubes required for a given application which then also reduces overall equipment size and can in the long-run decrease the cost of the project. In many application cases, one finned tube replaces six or more bare tubes at less than 1/3 the cost and 1/4 the volume.
