Key Features
1. Base Tube Material: ASME SA249 TP316L Stainless Steel
- TP316L Stainless Steel is a low-carbon variant of 316 stainless steel, known for its outstanding resistance to corrosion, especially in marine, chemical, and high-temperature environments.
- Offers excellent weldability and mechanical strength, making it suitable for high-pressure systems like air coolers and heat exchangers.
- It is highly resistant to chloride-induced stress corrosion and pitting, making it ideal for use in aggressive environments.
2. Fin Type: L-Type Wound Fin
- The L-type wound fin design involves a metal strip (usually aluminum) being tightly wound around the base tube, enhancing the heat transfer rate.
- L-type fins create an increased surface area, allowing for efficient heat dissipation and improved airflow, which makes them ideal for air coolers and other heat exchange systems.
- This design also reduces air-side resistance, improving the overall efficiency of the cooling process.
3. Fin Material: Al1100 Aluminum
- Al1100 is a high-purity aluminum alloy, known for its excellent thermal conductivity, light weight, and resistance to corrosion in various environments.
- The Al1100 fin material helps achieve efficient heat exchange while keeping the overall weight of the heat exchanger low, making it ideal for use in air cooler applications where high thermal efficiency and low weight are important.
4. Application: Air Cooler & Heat Exchanger
- This tube is designed specifically for air coolers, cooling towers, and heat exchangers, where the efficient exchange of heat between the fluid inside the tube and the surrounding air is essential.
- Its corrosion resistance and efficient heat transfer make it ideal for power plants, marine cooling systems, HVAC systems, and chemical processing plants.
