Brief: See how this offering can bring practical value to common tasks and projects. In this video, we explain the manufacturing process of spiral finned tubes, demonstrating how the controlled tension-winding technique creates a reliable mechanical bond. You'll learn about the enhanced air-side performance and corrosion-resistant properties that make these crimped fin tubes ideal for air coolers in demanding industrial applications.
Related Product Features:
  • Crimped fin tubes feature a helically wound fin strip under controlled tension for enhanced air-side heat transfer performance.
  • The pre-formed fin base increases contact area and is mechanically locked to the tube surface for reliable bonding.
  • Available in various material combinations including carbon steel, stainless steel, copper, and aluminum for corrosion resistance.
  • Designed with uniform pitch to reduce dust accumulation and support easier maintenance in air cooler applications.
  • Suitable for moderate temperature duty up to approximately 120°C, depending on configuration and materials.
  • Offers cost-efficient surface area gain without requiring heavier welded-fin constructions.
  • Provides good mechanical resistance against vibration and handling stresses in industrial environments.
  • Compatible with API 661 standards for refinery and petrochemical air-cooler procurement practices.
FAQs:
  • Will the fins loosen over time?
    No, the controlled tension-winding process with pre-formed fin base increases contact area, and fin ends are secured with tag/tack/spot fixing to stabilize the wrap for service and transport.
  • What temperature is this fin type suitable for?
    Crimped fin tubes are typically suitable for moderate temperature duty up to approximately 120°C, depending on configuration and materials. For higher temperatures, alternative fin constructions can be proposed.
  • How do I select base tube and fin materials for corrosion resistance?
    We support multiple material combinations including carbon steel, stainless steels, copper and more, allowing you to match process-side corrosion (base tube) and ambient-side corrosion (fin material) to your specific operating environment.
  • Do you provide inspection documents and traceability?
    Yes, we can provide EN 10204 3.1/3.2 material certification and support third-party inspection as required by project inspection and test plans.
