As a professional manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory is proud to offer our high-quality Stainless Steel Spiral Finned Tube for heat exchanger and cooling systems. Our finned tubes are designed to maximize heat transfer efficiency while maintaining excellent corrosion resistance, making them ideal for demanding industrial applications. With an annual export value of US$5-10 million and a strong global presence across North America, Europe, Asia, and more, we ensure reliable supply and consistent quality for every order.
Our spiral finned tubes are manufactured using advanced cold-rolling or high-frequency welding processes, ensuring a tight bond between the fin and the base tube. The stainless steel construction provides outstanding durability in harsh environments, including high temperatures, pressure fluctuations, and corrosive media. Whether you need custom dimensions, special fin geometries, or specific end connections, our factory can tailor the product to meet your exact requirements.
Key Features & Technical Specifications
- Material: Premium stainless steel (304, 316L, 310S, etc.) – excellent corrosion resistance and high-temperature strength.
- Fin Design: Helical spiral fins with uniform pitch and height for optimal heat transfer coefficient.
- Bond Strength: Fins are securely attached to the tube, ensuring long-term performance under thermal cycling.
- Customizable: Tube outer diameter from 16mm to 50mm, fin height from 10mm to 25mm, fin pitch from 4mm to 15mm, and length up to 18 meters.
- Surface Finish: Available in pickled, polished, or as-rolled condition – suitable for various installation environments.
- Applications: Used in shell-and-tube heat exchangers, air coolers, radiators, condensers, evaporators, and HVAC systems.
