Product Description

SA179 Carbon Steel Wound KL Finned Tubes for Industrial Air Coolers in Power Generation

Industrial air coolers in power generation are essential auxiliary equipment widely used in thermal power, nuclear power, and renewable energy power plants. These systems employ forced convection heat transfer with finned tube bundles as the core heat exchange elements to cool critical media, ensuring energy conservation and safe operation of power generation units.

As core components in power generation air coolers, wound L/LL/KL finned tubes primarily function to expand heat exchange surface area, enhance air-side heat transfer, and efficiently dissipate heat from process fluids to achieve optimal cooling performance.

KL Finned Tubes Advantages

Lower Thermal Resistance & Higher Heat Transfer Efficiency: Knurled base tube combined with rolled fin root creates mechanical interlock, reducing contact thermal resistance by 20-30% compared to L/LL types, and improving heat transfer coefficient by 10-15%. Ideal for air coolers and heaters requiring superior energy efficiency.
Superior Structural Reliability & Thermal Shock Resistance: Enhanced fin-tube bonding surpasses tension winding/overlapping methods. Resists fin loosening and detachment under temperature fluctuations and vibration conditions (e.g., compressor cooling, waste heat recovery). Service life extended by 30-50%.
Better Corrosion Resistance & Sealing: Tighter fin-root and base-tube fit minimizes crevice corrosion. Mechanical interlock effectively blocks moisture, salt, and corrosive elements compared to LL type. Excellent performance in wet air cooling, coastal, and chemical environments.
Higher Maximum Operating Temperature: GB/T 15386-94 standard permits maximum operating temperature of 250℃ (up to 280℃ for some suppliers), significantly higher than L (≤150℃) and LL (≤170-180℃) types. Suitable for 180-250℃ medium-temperature processes including heat medium heating and flue gas waste heat recovery.

Fin Material Options

Aluminum

Common grades include Alu.1100 and Alu.1060. Aluminum fins offer light weight, excellent thermal conductivity, and good corrosion resistance, making them widely used in applications with weight constraints and moderate corrosive conditions.

Copper

Copper provides superior thermal conductivity, suitable for scenarios demanding extremely high heat transfer efficiency, such as precision instrument cooling. However, application scope is more limited compared to aluminum due to higher cost and increased weight.

Steel

Steel fins deliver high strength, capable of withstanding elevated pressure and temperature conditions. Applicable to high-temperature, high-pressure working environments. Thermal conductivity is lower than aluminum and copper, typically requiring fin structure optimization to enhance heat transfer efficiency.
