What is fin tube ?
Finned tube is a heat exchanger element. In order to improve the heat exchange efficiency, the surface area (or internal surface area) of the heat exchange tube is usually increased by adding fins on the surface of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency, such a heat exchange tube.
About the Embedded fin tube
Extruded fin tubes are a type of heat exchanger tube that have fins on the outside surface. These fins are typically made of aluminum, although other materials such as copper or stainless steel can also be used. The fins are attached to the tube by an extrusion process, where the metal is forced through a die to create the desired shape.
Extruded fin tubes are commonly used in applications where heat transfer is important, such as in air conditioning systems, refrigeration units, and power plants. The fins increase the surface area of the tube, allowing for more efficient heat transfer between the fluid inside the tube and the surrounding environment.
The extrusion process used to create the fins on the tube allows for a high degree of customization. The fins can be made in various shapes and sizes, depending on the specific requirements of the application. This flexibility makes extruded fin tubes suitable for a wide range of heat transfer applications.
Performance requirement
As a heat exchange element, the fin tube works in the condition of high temperature flue gas for a long time, such as the fin tube used in the boiler heat exchanger has a harsh environment, high temperature and high pressure and is in a corrosive atmosphere, which requires the fin tube to have a high performance index.
1) Anti-corrosion performance
2), wear resistance (Anti-wear)
3), low contact resistance 4), high Stability (Higher Stability)
5), anti-ash ability
EN 10217-7 is a European standard for welded steel tubes for pressure purposes. It specifies the technical delivery conditions for circular welded tubes made of austenitic stainless steels.
1.4301 is the material grade specified in EN 10217-7 for the austenitic stainless steel. It is also known as AISI 304 or UNS S30400. This material is widely used in various industries due to its excellent corrosion resistance, good formability, and high strength.
Extruded fin tube refers to a type of heat exchanger tube that has fins on its outer surface. These fins increase the surface area of the tube, allowing for better heat transfer between the fluid inside the tube and the surrounding environment. Extruded fin tubes are commonly used in applications where efficient heat transfer is required, such as in boilers, air conditioning systems, and heat exchangers.
In summary, EN 10217-7 1.4301 extruded fin tube refers to a welded steel tube made of austenitic stainless steel (1.4301) that has fins on its outer surface, designed for efficient heat transfer in various industrial applications.
