L Type Fin Tube Wound Fin Tube ASME SA249 TP316L With Al1100 For Air Cooler
Product Overview
The L Type Fin Tube, also known as a wound fin tube, is manufactured using ASME SA249 TP316L stainless steel as the base tube, with Aluminum 1100 (Al1100) fins mechanically wound around the tube. This type of finned tube is widely used in air coolers, heat exchangers, and condensers, offering high efficiency, corrosion resistance, and durability.
Key Features
Base Tube Material: ASME SA249 TP316L Stainless Steel
- Corrosion-resistant in high-temperature and chemical environments.
- Provides high mechanical strength and longevity.
- Ideal for marine, power plants, and chemical industries.
Fin Material: Aluminum 1100 (Al1100)
- Excellent thermal conductivity, ensuring efficient heat transfer.
- Lightweight and resistant to oxidation.
- Provides an economic and effective cooling solution.
Fin Type: L Type Wound Fin
- Mechanically wound aluminum fins tightly grip the base tube.
- Ensures maximum heat transfer with minimal thermal resistance.
- Ideal for low to moderate temperature applications.
Application: Air Coolers & Heat Exchangers
- Used in air-cooled condensers, refrigeration systems, and process cooling.
- Suitable for HVAC systems, petrochemical plants, and power stations.
