| Aperture | Φ20/Φ25/Φ32mm | Custom-specific holes supported | Compatible with mainstream fin tube machine models |
Blade material is customized based on tube type (copper, aluminum, stainless steel, carbon steel) and process intensity. We provide high-wear-resistant alloy as standard, with upgrade options for high-hardness, corrosion-resistant, or high-temperature conditions. Our engineers evaluate your specific application to recommend optimal materials.
Excessive pitch error causes uneven fin spacing, directly reducing heat transfer efficiency (each 0.1mm increase can decrease efficiency by 2%-5%). Our blade pitch accuracy of ≤0.03mm ensures consistent fin formation, meeting industry standards for finned tubes, boilers, and heat exchangers.
Lifespan varies by material and conditions: 3,000-5,000 meters for copper/aluminum tubes, 1,500-2,000 meters for hard stainless steel tubes. Extend blade life by regularly cleaning surface residue, matching equipment torque to avoid overloading, and selecting appropriate blade angles based on pipe hardness.
