A179 Carbon Steel Spiral Finned Tubes

A179 spiral finned tube is a high-efficiency heat exchange element. One or more finned tubes are combined and connected to form a complete heat dissipation device. Water, steam, and heat transfer oil circulate back and forth in a closed heat dissipation pipe to achieve the purpose of heat conduction.

A179 Spiral Finned Tube Technical Advantages

1. Long service life, more than 3 times that of spiral welded finned steel tubes.

2. The fin root forms an arc cut with the tube, and the fin surface is smooth, completely eliminating the problems of ash accumulation, ash blockage, and slag buildup that easily occur in other types of finned tubes due to uneven fin root folds.

3. Manufactured using a hot rolling process, improving the density, yield strength, tensile strength, and wear resistance of the metal structure.

4. Because the fins and tube are an integral structure with a spiral distribution, the pressure-bearing capacity of the integral spiral finned steel tube is more than 3 times that of seamless steel tubes of the same wall thickness and inner diameter.

5. Wear-resistant, solving the problem of severe wear on the convective heating surfaces of coal-fired boilers due to high wind speeds and high ash concentrations. (Especially for circulating fluidized bed boilers)

6. The fins and tubes are integrated into a single structure, completely eliminating the contact thermal resistance inherent in other types of finned steel tubes where the fins and tubes are separate components. Furthermore, the trapezoidal longitudinal section of the fins maximizes heat exchange efficiency.

7. The use of integral spiral fins expands the surface heat exchange. Under the same operating conditions, the heat transfer coefficient of the tube bundle is 3.5-5.5 times that of seamless steel tubes of the same wall thickness and inner diameter, and twice that of welded spiral finned steel tubes of the same specifications.

8. Because the fins and tubes are integrated, in high-temperature and harsh environments, the unstable heat transfer performance caused by fin loosening or detachment, common in other types of finned steel tubes, is avoided.

Application Areas Of A179 finned tube

Due to their superior heat exchange performance, spiral finned tubes are widely used in various heat exchange equipment, including but not limited to:

1. Boilers and Water Heaters: In boilers and water heaters, spiral finned tubes serve as the primary heat exchange element, effectively improving the heating speed and efficiency of hot water while reducing energy consumption.

2. Petrochemical Industry: In the petrochemical industry, spiral finned tubes are commonly used in various heat exchangers, condensers, and reboilers to handle corrosive or viscous fluids under high temperature and pressure, ensuring the continuity and stability of the production process.

3. Refrigeration and Air Conditioning: In refrigeration systems and air conditioning equipment, spiral finned tubes, as the core component of evaporators or condensers, can efficiently exchange heat, improving cooling or heating effects and reducing energy consumption.

4. Waste Heat Recovery: In industries such as steel, cement, and glass, spiral finned tubes are used in waste heat recovery systems to convert waste heat generated during production into useful thermal energy, achieving energy recycling.
