High Light High Temperature Resistance Serrated Fin TubeCorrosion Resistance Studded TubeEnhanced Turbulence Disturbance Finned Tube

ASTM A312 TP304H serrated finned tubes are an ideal choice for high-temperature heat exchange systems in industrial dust-laden workshops. They are particularly suitable for devices such as waste heat recovery, warm air heating, and air preheating in industries such as metallurgy, casting, chemical engineering, building materials, and mining. These tubes not only effectively address the combined challenges of "high temperature + heavy dust + corrosion" but also significantly enhance energy utilization efficiency, reduce operational and maintenance costs, and contribute to green and energy-saving production.

  1. High Temperature Resistance – Adaptable to High-Temperature Dust-Laden Airflow

    • High Operating Temperature: TP304H is a high-temperature grade austenitic stainless steel with a relatively high carbon content (0.04–0.10%). It can operate stably for extended periods at temperatures up to 650°C, making it suitable for dust-laden workshops in industries such as metallurgy, casting, and sintering, where high-temperature flue gas or hot air is generated.
    • Strong Creep Resistance: Compared to ordinary TP304, TP304H is less prone to plastic deformation and stress relaxation under high-temperature pressure conditions, ensuring equipment safety.
  2. Corrosion Resistance – Withstanding Complex Pollutant Erosion

    • Chemical Corrosion Resistance: With chromium content exceeding 18% and nickel content ranging from 8% to 11%, it offers strong resistance to common weak acidic/alkaline gases (such as SO₂and NH₃), moisture, and salt spray typically found in workshop environments.
    • Strong Oxidation Resistance: In high-temperature air environments, a dense chromium oxide film forms on the surface, preventing continuous oxidation and spalling.
    • Superior Pitting and Crevice Corrosion Resistance Compared to Carbon Steel: Particularly suitable for dust-laden workshops with high humidity and frequent condensation.
  3. Design Advantages of Serrated Fin Tube

    Enhanced Turbulence Disturbance:

    • The serrated edges disrupt the air boundary layer, significantly increasing the convective heat transfer coefficient. Heat exchange efficiency is improved by 15%–25% compared to straight fins.
    • Effective heat transfer is maintained even at low wind speeds, making it suitable for natural convection or low-speed fan-driven systems.

    Reduced Ash Accumulation and Clogging:

    • The serrated structure creates irregular airflow paths, preventing uniform dust buildup along the fins.
    • Loose dust can be partially blown away under airflow impact, providing a degree of "self-cleaning" functionality.
    • Compared to spiral fins, serrated fins are less prone to tangling with fibrous impurities.

(Practical Benefits: Extended ash-cleaning cycles, reduced maintenance frequency, and sustained high-efficiency operation over the long term.)
