Advanced radiator tubes with Aluminum Fins featuring Base Tubes made of Copper Alloy, Stainless Steel, Carbon Steel, Copper-Nickel, or Titanium. Compliant with ASME SA179, SA192, and SA210 standards.
Manufactured to the highest industry standards for reliability.
Extensive selection of geometries and high-performance materials.
Significant price savings through optimized production processes.
The perfect bond between fin and tube improves efficiency in heat transfer and resistance to corrosion resulting in a clean weld fin to tube joint and fully straight fins (no corrugation).
Modified surface tubes are manufactured from plain tubes conforming to ASTM Specifications: A179/A179M, A214/A214M, or A334/A334M. These are produced by cold forming, ensuring the surface and tube material are integral. Finished tubes are straight, smooth, and free from burrs or injurious defects.
| Product Type | Tube Material | Fin Material | Tube Size (mm) | Fin Size |
|---|---|---|---|---|

Our finned tubes are essential components for: Aftercoolers, air heaters, charge air chillers, condensers, convection heaters, evaporators, fluid coolers, gas coolers, heat pipes, hydrogen coolers, industrial tumble dryers, oil coolers, radiators, and refrigeration systems.
We offer base tubes in a variety of materials including Copper Alloy, Stainless Steel, Carbon Steel, Copper-Nickel, and Titanium to suit different corrosive environments and heat transfer needs.
Our products are manufactured according to global standards such as ASME SA179, SA192, SA210, and ASTM A179/A179M, A214/A214M, and A334/A334M.
Annealed condition means both the modified (finned) and unmodified portions meet standard heat-treatment requirements. As-cold-worked means the finned area retains the properties produced by the cold-forming operation while the ends meet plain tube requirements.
Yes, we provide specifications ranging from 18mm to 273mm and offer CNC machining and cutting services to produce tubes exactly according to your technical drawings.
We offer several types including Extruded Fin Tubes, L-Foot (Wrap On), G-Fin (Embedded), High-Frequency Welded, and Monometallic Low Fin tubes.
Tubes can be shipped bare or in protective packaging such as Nylon, Canvas, or Wooden boxes, with mandatory markings on tags securely attached to each bundle.
