Product Description

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.

Good strength, handles the pressure, no corrosion issues so far. We're running treated water, so no complaints.

Been running about 6 months now in cyclic service. No leaks, no failures. Heat transfer still where it should be.

Using these in oil and gas heat exchangers. Checked the material reports and everything is perfect. These extruded tubes have high strength, making installation a breeze. The seller was patient and helped with all our technical questions.
