ASME SA249 TP304 extruded finned tubes are high-performance heat transfer components designed for air cooler applications where corrosion resistance, mechanical strength, and long-term operating stability are required.
The product uses ASME SA249 TP304 stainless steel as the base tube material, with an aluminum outer fin layer typically formed through an extrusion process. During manufacturing, the aluminum fin material is mechanically bonded onto the outside surface of the tube, creating a tight contact between the fin and tube wall.
This structure improves heat transfer efficiency while providing enhanced protection against environmental corrosion. These extruded finned tubes are widely used in air-cooled heat exchangers, industrial cooling systems, petrochemical plants, power facilities, and process equipment.
The extruded finned tube consists of:
During extrusion, the aluminum sleeve is mechanically expanded and compressed around the stainless steel tube surface. This creates a strong mechanical bond without relying on welding.
The integrated structure provides:
ASME SA249 TP304 extruded finned tubes are commonly applied in:
Used in refineries, chemical plants, and process industries where cooling fluids must exchange heat with ambient air.
Suitable for cooling:
The stainless steel tube provides better resistance against moisture, oxidation, and mildly corrosive process environments.
Used in:
Applied in:
The following dimensions are commonly available depending on project requirements:
| Item | Typical Range |
|---|---|
| Base Tube OD | 15.88 mm – 38.1 mm (5/8" – 1 1/2") |
| Tube Wall Thickness | 1.0 mm – 3.5 mm |
