Air Cooler Tube ASTM A179 Carbon Steel Fin Tube L Type Wound Fin Tube OD25.4MM

Key Features:

  1. Base Tube Material: ASTM A179 Carbon Steel, a seamless carbon steel tube known for its excellent strength, durability, and thermal conductivity, widely used in heat exchangers and air cooler systems.
  2. Fin Material: L Type Wound Fin, which is wrapped around the tube in a spiral pattern to create an increased surface area, improving heat exchange efficiency and promoting better cooling.
  3. Outer Diameter (OD): 25.4 mm, a commonly used size for air cooler tubes that provides an optimal balance between strength, flexibility, and heat transfer performance.
  4. Application: This type of wound fin tube is designed specifically for use in air coolers, where efficient heat dissipation is required for cooling air or fluid systems.
