Carbon Steel Seamless Tube, ASTM A179 Wound Fin Tube, L Type, For Air Cooler

The ASTM A179 L-type fin tube is primarily used in the tube bundle section of an Air-Cooled Heat Exchanger (ACHE) — commonly known as a fin fan cooler. Within this system, it plays a crucial role in the air-side heat transfer process.

Chemical Composition (ASTM A179 - Base Tube)

Element	Content (%)
Carbon (C)	≤ 0.06
Manganese (Mn)	0.27 – 0.63
Phosphorus (P)	≤ 0.035
Sulfur (S)	≤ 0.035

Mechanical Properties (ASTM A179)

Property	Value
Tensile Strength	≥ 325 MPa
Yield Strength	≥ 180 MPa
Elongation	≥ 35%

Key Advantages

Cost-Effective: ASTM A179 carbon steel is economical for non-corrosive environments.
Efficient Heat Transfer: L-type fin design ensures close metal contact between the tube and the fin for effective thermal performance.
Simple Fabrication: Easy to produce and maintain.
Durability: Wound fins resist vibration and mechanical stress in air cooler operation.

Application:

In a refinery, the ASTM A179 Carbon Steel L-Type Wound Fin Tube is typically used in the Air-Cooled Heat Exchanger (ACHE) units, specifically in the tube bundle section of the cooling system.

How It Works in Refinery ACHEs:

Hot hydrocarbon fluid (from a column or reactor) flows inside the A179 carbon steel tube.
Aluminum L-type fins wound around the tube surface increase the surface area for air-side heat rejection.
Large axial fans force ambient air across the finned tube bundle.
Heat transfers from the fluid to the tube wall → to the fins → to the air.
The cooled fluid is sent to the next processing step or storage.
