Breve: In this walkthrough, we highlight key design ideas and how they translate to performance. Discover how Aluminum L-Foot Tension Wound L-Type Fin Tubes are manufactured and why their mechanical bond and material combination make them ideal for corrosion-resistant heat exchangers in various industrial applications.
Recursos de Produtos Relacionados:
  • High heat transfer efficiency from aluminum fins with excellent thermal conductivity and large external surface area.
  • Secure mechanical fin-tube bond via tension-wound L-foot design prevents fin movement under thermal cycling and vibration.
  • Improved corrosion protection as the fin foot shields the base tube from direct atmospheric exposure.
  • Optimized for air-cooled service in heat exchangers, radiators, and process gas coolers.
  • Flexible material combinations allow base tubes of carbon steel, stainless steel, or non-ferrous materials.
  • Cost-effective solution compared to extruded fin tubes while maintaining reliable performance.
  • Compatible with standard cleaning procedures like air-blow or low-pressure water wash.
  • Manufactured to international standards including ASTM, EN, GOST, JIS, and GB/T.
FAQ:
  • Will the fins loosen or rattle under vibration and thermal cycling?
    The L-foot profile and controlled tension winding create a mechanical interlock that resists fin lifting and movement, ensuring stability in typical operating conditions up to about 400-450 °F.
  • How is base-tube corrosion controlled, especially outdoors or in coastal plants?
    The aluminum L-foot covers the tube surface, acting as a barrier. Fin and tube alloys are selected to minimize galvanic effects in aggressive environments.
  • Can you match my existing bundle design (OD, fin height, FPI, length)?
    We support typical tube ODs from 1/2" to 2", fin heights from 1/4" to 5/8", fin pitches from 5 to 13 FPI, and lengths up to ~15-18 m, covering most common applications. Custom geometries are also available.
  • What are your delivery times?
    Generally 10-15 days for in-stock items and 30-40 days for non-stock items, depending on quantity.
