Stainless Steel Extruded Finned Tube SA249 TP304 Welded Tube With Aluminum Fin

Stainless steel extruded finned tube

Stainless steel extruded finned tubes are an efficient heat exchanger material commonly used in industrial equipment systems. It adopts a unique extrusion process that tightly combines stainless steel pipes and fins, increasing their surface area and improving heat transfer efficiency, thereby achieving more efficient heat transfer effects.

Stainless steel extruded finned tubes have advantages such as high strength, high temperature resistance, corrosion resistance, and wear resistance, as well as good dimensional accuracy and surface finish. In the field of industrial equipment, stainless steel extruded finned tubes are widely used in power plants, chemical industry, petrochemical, pharmaceutical and other fields. As an important heat exchange material, the manufacturing process and quality requirements for stainless steel extruded finned tubes are very high.
During the manufacturing process, it is necessary to ensure a tight fit between the fins and the pipes, otherwise it will reduce their heat transfer efficiency. At the same time, its surface should have a high degree of smoothness and a certain degree of corrosion resistance. Therefore, in the manufacturing process, it is necessary to strictly control every step to ensure that the product meets the high quality requirements. In summary, stainless steel extruded finned tubes have a wide range of applications and play an irreplaceable role in both industrial and automotive fields.

Benefits:

• Enhanced Thermal Conductivity: Due to the increased surface area, heat transfer is more efficient.

• Corrosion Resistance: Stainless steel's ability to resist corrosion makes it suitable for use in aggressive environments.
• Long Service Life: Stainless steel is durable and able to withstand high temperatures and mechanical stresses.

Types of finned tubes

• 1. Extruded aluminum fin is in the form of base tube sleeve aluminum tube. (The base tube can be made of carbon steel, stainless steel, copper) After being extruded by the machine, the fin is formed. The base of the fin is closely connected with the outer wall of the tube, with high Heat transfer coefficient and excellent heat transfer performance.
• 2. The wrapped finned tube is in the form of a steel strip wrapped around the base tube, which can be made of copper, aluminum, carbon steel, or stainless steel. This type of finned tube is suitable for a variety of types, such as stainless steel wound tubes, which can be used in situations with high quality requirements. The disadvantage is that the steel strip is not fully fitted with the outer wall of the base tube, but is vertically stressed on the surface of the base tube, and the Heat transfer coefficient is slightly low.
• 3. High frequency welded tubes are commonly used for base tubes with a diameter of 10-219mm. They are welded onto the surface of the base tube using the principle of high-frequency welding. This type of finned tube has a high heat transfer coefficient, high fin thickness, and is more sturdy compared to other finned tubes, making the fins relatively less prone to damage. Long service life and good effect.
