خلاصه: Watch our dynamic showcase of the Alloy Steel Spiral Wound Finned Tube with L Foot! This video demonstrates how the unique L-foot fin geometry enhances heat transfer efficiency in industrial heat exchangers. You'll see close-up views of the spiral winding process and learn how this design provides superior thermal contact and corrosion protection for demanding applications.
ویژگی‌های مرتبط با محصول:
  • Features an alloy steel core tube with helically wound L-foot fin strip for enhanced thermal contact.
  • L-foot fin geometry ensures tight contact with tube surface, dramatically improving heat transfer efficiency.
  • Spiral winding provides continuous coverage, significantly increasing external surface area compared to bare tubes.
  • Fins act as a protective cover for the tube wall, offering corrosion protection from the air side.
  • Tension-wound construction allows for thinner core tubes and minimal modification of base material.
  • Suitable for operating temperatures up to 230°C on the fin side in air-cooled heat exchangers.
  • Available in various material grades including ASTM A213 T11, T22, EN 13CrMo4-5, JIS STBA22, and GB 12Cr1MoVG.
  • Custom dimensions and surface-coating options available to match specific heat-exchanger requirements.
متداول:
  • Will the fins remain firmly attached under thermal cycling and high-velocity air vibration?
    Our L-foot finned tubes use controlled tension in the fin strip winding to ensure tight foot contact on the tube, minimizing loosening under start-stop cycling, vibration, or thermal shocks.
  • Is the L-foot fin the right choice compared to other fin types for my application?
    Yes, if your air-side fin temperature is moderate (up to ~230°C) and you want a cost-effective solution with high surface area. For more severe duties, we can advise upgraded fin types or alternate materials.
  • How about corrosion resistance and maintenance for these finned tubes?
    The fin serves to shield the tube wall, reducing direct exposure to ambient air and corrosion potential. Increased heat-transfer efficiency also means fewer tubes are required, reducing bundle volume and associated structure costs.
  • What is your delivery time for these finned tubes?
    Generally 10-15 days if goods are in stock, or 30-40 days if not in stock, depending on quantity.
